Female Hormone Test Guide (India 2026): LH, FSH, Prolactin & Irregular Periods
अनियमित पीरियड्स और PCOD? LH, FSH और Prolactin टेस्ट को समझें — नॉर्मल रेंज, PCOS Pattern और Report Reading
Your gynaecologist has ordered LH, FSH, and Prolactin — three hormones that tell the complete story of why your periods are irregular, why ovulation isn't happening, or why fertility is a concern. These three tests, drawn on Day 2 or Day 3 of your menstrual cycle, are the most important first-line hormonal investigations for any woman with irregular periods, PCOS/PCOD, infertility, or unexplained milk discharge. Yet their results are widely misread — a high LH is not always PCOS, and a "normal" FSH may not mean good ovarian reserve at 38. This guide explains each clearly.
LH, FSH, और Prolactin — तीन hormones जो irregular periods, anovulation, और fertility concern की पूरी कहानी बताते हैं। Cycle के Day 2 या 3 पर collect। अक्सर misread: High LH = always PCOS नहीं; "Normal" FSH at 38 = अच्छी ovarian reserve नहीं मतलब। यह guide clearly explain करती है।👁 Table of Contents / विषय सूची

What Are LH, FSH & Prolactin?
All three hormones are produced by the anterior pituitary gland. Together, they form the hypothalamic-pituitary-ovarian (HPO) axis — the hormonal control system that governs the menstrual cycle, ovulation, and fertility. Each has a distinct role, a distinct normal range, and a distinct clinical meaning when it is elevated or suppressed.
तीनों hormones anterior pituitary gland से। Together = HPO (Hypothalamic-Pituitary-Ovarian) axis — menstrual cycle, ovulation, और fertility का hormonal control system। Each की distinct role, normal range, और clinical meaning है।FSH is produced by the pituitary in the first half of the cycle (follicular phase) and drives the growth of ovarian follicles. Each follicle contains one egg. As follicles grow, they produce oestrogen, which feeds back to suppress FSH — a negative feedback mechanism that normally leads to selection of just one dominant follicle for ovulation. High FSH on Day 2–3 means the pituitary is "shouting louder" to stimulate an ovary that is not responding normally — indicating reduced ovarian reserve (fewer or lower-quality eggs). Low FSH means the pituitary signal is suppressed — seen in hypothalamic amenorrhea (stress, weight loss, excessive exercise), or in PCOS where oestrogen feedback is disrupted. FSH = follicle growth drive करता है। High Day 2–3 FSH = pituitary "louder shouting" = ovary ठीक से respond नहीं → reduced ovarian reserve। Low FSH = suppressed signal (stress, weight loss, excessive exercise = hypothalamic amenorrhea; या PCOS)।
LH has two roles: a basal low level in the first half of the cycle, and then a dramatic LH surge at mid-cycle (Day 13–15) that triggers ovulation. After ovulation, LH stimulates the ruptured follicle to become the corpus luteum, producing progesterone for the second half of the cycle. On Day 2–3, LH should be low and roughly equal to FSH (LH:FSH $\approx 1:1$). In PCOS, LH is chronically elevated relative to FSH — causing excess androgen production and disrupting the normal follicle development cycle. LH is also measured mid-stream in urine by ovulation predictor kits (OPKs) to detect the LH surge and time intercourse for conception. LH: first half में basal level + mid-cycle dramatic surge → ovulation trigger। Post-ovulation: corpus luteum → progesterone। Day 2–3: LH low = FSH के roughly equal। PCOS: LH chronically elevated → excess androgens → follicle development disrupt।
Prolactin is the hormone that stimulates breast milk production (lactation). Its primary physiological role is in breastfeeding — high prolactin during breastfeeding suppresses GnRH from the hypothalamus → suppresses FSH and LH → prevents ovulation (the basis of lactational amenorrhea). Pathologically, high prolactin from any cause mimics the breastfeeding state — suppressing FSH and LH → no ovulation → irregular or absent periods. Prolactin is also a stress hormone — cortisol and dopamine regulate it — explaining why prolactin rises with stress, sleep deprivation, and anxiety. Any woman with irregular periods, galactorrhoea (milk discharge from breasts when not breastfeeding), or fertility concerns should have prolactin tested. Prolactin = breast milk production। Breastfeeding में: high prolactin → GnRH suppress → FSH/LH suppress → no ovulation (lactational amenorrhea)। Pathologically elevated: irregular/absent periods + galactorrhoea। Stress hormone भी — cortisol + dopamine regulate।
The hypothalamic-pituitary-ovarian (HPO) axis is a beautifully regulated feedback system. Hypothalamus releases GnRH (in pulses) → Pituitary releases FSH and LH → Ovary produces oestrogen + progesterone → These hormones feed back to the hypothalamus and pituitary to regulate GnRH, FSH, and LH. Prolactin sits outside this cycle but suppresses GnRH when elevated. Disruption at any level — hypothalamus (stress, low weight), pituitary (tumour, Sheehan's syndrome), or ovary (PCOS, premature ovarian failure) — produces characteristic hormone patterns that the FSH/LH/Prolactin panel reveals. Always test with AMH (ovarian reserve), TSH, and testosterone alongside LH/FSH/Prolactin for a complete hormonal picture. HPO axis: Hypothalamus (GnRH pulses) → Pituitary (FSH + LH) → Ovary (oestrogen + progesterone) → Feedback। Prolactin = GnRH suppress when elevated। Complete hormonal picture: FSH/LH/Prolactin + AMH + TSH + Testosterone।
Normal Range & When to Test
*Reference ranges vary between labs and assay platforms. Units: mIU/mL (= IU/L) for FSH and LH; ng/mL (= µg/L) for Prolactin. FSH and LH values are phase-dependent — always note which phase the blood was collected in. The most clinically useful collection point is Day 2–3 (basal/follicular phase).
Reference ranges labs के बीच vary। FSH और LH phase-dependent — always note कौन से phase में collect किया। Most useful: Day 2–3 (basal follicular phase)।| Hormone | Day 2–3 (Basal) — Most Important | Mid-Cycle (Ovulation Surge) | Luteal Phase (Day 21–23) |
|---|---|---|---|
| FSH | $3\text{ to }10\text{ mIU/mL}$ (normal); $10\text{ to }12$ = reduced ovarian reserve; $> 40$ = ovarian failure / menopause |
Peak: $4\text{ to }25\text{ mIU/mL}$ (LH surge co-occurs) | $1\text{ to }5\text{ mIU/mL}$ (falls after ovulation) |
| LH | $2\text{ to }8\text{ mIU/mL}$ (normal Day 2–3); LH:FSH ratio should be $\le 1:1$ or $\le 2:1$ |
Surge peak: $25\text{ to }100\text{ mIU/mL}$ — ovulation occurs ~36 hours after surge onset | $0.5\text{ to }16\text{ mIU/mL}$ (falls post-ovulation) |
| Prolactin | Normal (non-pregnant): $2\text{ to }29\text{ ng/mL}$ (lab-dependent) Slightly higher in women than men. Rises significantly in pregnancy (up to $200\text{ to }300\text{ ng/mL}$ at term) and breastfeeding (up to $> 300\text{ ng/mL}$). Mildly elevated ($30\text{ to }60\text{ ng/mL}$): stress, hypothyroidism, medications. Moderately elevated ($60\text{ to }200\text{ ng/mL}$): prolactinoma (small), medications. Severely elevated ($> 200\text{ ng/mL}$): macroadenoma likely. |

The most common error in Indian patients getting FSH/LH tests: counting the first day of spotting as Day 1, then coming on Day 3 of spotting — which is actually Day 3+ of the cycle but only Day 1+ of real flow. Day 1 = first day of full menstrual flow (red blood, not just brown spotting). Come on Day 2, 3, or 4 of full flow. If your periods are irregular and you don't know when your next period will start: your gynaecologist may order the test on any day or use progesterone withdrawal to induce a bleed first. Do not delay the test — contact your gynaecologist's office for guidance on when to come in.
Most common error: Spotting के पहले दिन को Day 1 मानना। Day 1 = FULL FLOW का पहला दिन (red blood — brown spotting नहीं)। Day 2, 3, या 4 of full flow पर come करें। Irregular periods में: gynaecologist guidance लें — progesterone withdrawal से bleed induce करके test हो सकता है।PCOS/PCOD Pattern — LH:FSH Ratio >2 & What It Means
$$\text{LH}:\text{FSH Ratio} \ge 2:1$$
PCOS (Polycystic Ovarian Syndrome) — called PCOD (Polycystic Ovarian Disease) in India — is the most common endocrine disorder in women of reproductive age, affecting approximately 1 in 5 Indian women. The hormonal pattern of PCOS is characteristic and instructive:
PCOS (India में PCOD) = most common endocrine disorder in women of reproductive age — India में approximately 1 in 5 women। PCOS का hormonal pattern characteristic और instructive है।Classic biochemical PCOS pattern on Day 2–3:
- LH elevated (often $8\text{ to }20\text{ mIU/mL}$) — chronically high LH stimulates ovarian thecal cells to produce excess androgens (testosterone)
- FSH normal or low-normal ($3\text{ to }8\text{ mIU/mL}$) — FSH is relatively suppressed
- LH:FSH ratio above $2:1$ (classic PCOS criterion — though not all PCOS has this; Rotterdam criteria do not require it)
- Testosterone elevated — check free + total testosterone; causes hirsutism (facial/body hair), acne, scalp hair thinning (androgenic alopecia)
- AMH elevated ($> 4\text{ to }5\text{ ng/mL}$) — the clearest biochemical PCOS marker; see our AMH guide
- Prolactin slightly elevated (in some PCOS patients) — secondary to oestrogen elevation
- Insulin resistance — check fasting insulin, HOMA-IR, and HbA1c — insulin resistance is present in $\ge 70\%$ of Indian PCOS
The mechanism: normally, FSH in the follicular phase stimulates multiple small follicles, one of which becomes dominant and matures to ovulation. In PCOS, the chronic LH excess creates an environment of excess androgens in the ovary → androgens impair follicle maturation → multiple small follicles start but none reaches dominant maturity → no ovulation (anovulation) → no progesterone production → no shedding of the uterine lining at the expected time → irregular or absent periods. The ultrasound appearance: multiple small follicles arranged like a "string of pearls" around the ovary periphery — $\ge 12$ follicles of $2\text{ to }9\text{ mm}$ in each ovary on transvaginal ultrasound. Clinical options under medical guidance often include: structured lifestyle changes (weight management of $5\%\text{ to }10\%$ may help reduce metabolic stress and support normal periods), and specialized therapeutic agents evaluated by your physician. Mechanism: LH excess → excess androgens in ovary → follicle maturation impair → multiple small follicles, none dominant → no ovulation → no progesterone → irregular/absent periods। Ultrasound: "string of pearls" — $\ge 12$ follicles ($2\text{ to }9\text{ mm}$) per ovary। Treatment: $5\%\text{ to }10\%$ weight loss (normalises LH in many), medical consult for specialized therapies (fertility)।
High FSH — Ovarian Reserve Decline & Perimenopause
Elevated FSH on Day 2–3 is not just about PCOS — it signals the opposite problem. While low/normal FSH in PCOS reflects adequate oestrogen feedback suppressing FSH, a high FSH on Day 2–3 means the ovary is not producing enough oestrogen to suppress pituitary FSH — indicating reduced ovarian reserve, perimenopause, or ovarian failure.
High Day 2–3 FSH = PCOS का opposite problem। Low/normal FSH in PCOS = adequate oestrogen suppressing FSH। High FSH = ovary enough oestrogen produce नहीं कर रही → reduced ovarian reserve, perimenopause, या ovarian failure।As a woman ages (or due to conditions that damage the ovaries — endometriosis, previous ovarian surgery, chemotherapy), the pool of remaining follicles (ovarian reserve) declines. With fewer follicles, less oestrogen is produced in the early follicular phase → the pituitary detects low oestrogen → releases more FSH (trying harder to stimulate the ovary). This elevated basal FSH is the earliest blood marker of reduced ovarian reserve. Interpretation: Day 2–3 FSH $10\text{ to }12\text{ mIU/mL}$: borderline — poor ovarian response to stimulation in IVF; $12\text{ to }20\text{ mIU/mL}$: significantly reduced reserve; above $20\text{ mIU/mL}$: very poor reserve. However, FSH alone is an incomplete picture — AMH (Anti-Müllerian Hormone) is now the preferred marker of ovarian reserve. See our AMH guide. High FSH with low AMH = genuinely poor ovarian reserve. Fewer follicles → less oestrogen → pituitary more FSH release। Day 2–3 FSH: $10\text{ to }12$ = borderline; $12\text{ to }20$ = significantly reduced; >$20$ = very poor। AMH = preferred ovarian reserve marker (see AMH guide)। High FSH + Low AMH = genuinely poor reserve।
Premature Ovarian Insufficiency (POI) — previously called premature menopause — is defined as ovarian failure (FSH above $25\text{ to }40\text{ mIU/mL}$ on two measurements, 4 weeks apart) before age 40. It affects approximately $1\%$ of women under 40 and $1\text{ in }1,000$ under 30. Causes: autoimmune (the most common identifiable cause — the immune system attacks the ovary; associated with thyroid autoimmunity, Addison's disease); Turner syndrome (45,X — genetic); fragile X premutation (FMR1 gene); chemotherapy/radiation; idiopathic (50% — no identifiable cause). Symptoms: irregular or absent periods; hot flashes; night sweats; vaginal dryness; mood changes; infertility. A young Indian woman with FSH above 25 on Day 2–3 should have a second FSH measurement in 4 weeks, thyroid antibodies (anti-TPO), adrenal antibodies, and karyotype. POI (Premature Ovarian Insufficiency): FSH >$25\text{ to }40\text{ mIU/mL}$ on two measurements 4 weeks apart, before age 40। Causes: autoimmune (most common), Turner syndrome, fragile X, chemotherapy, idiopathic। Young woman में high FSH: 4-week repeat + anti-TPO + adrenal antibodies + karyotype।
As ovarian reserve naturally declines through the 40s: Day 2–3 FSH begins rising above 10, then 15, then $20\text{ mIU/mL}$. Simultaneously, LH rises. The periods become irregular and eventually cease. Menopause = absence of periods for 12 consecutive months. FSH above $40\text{ mIU/mL}$ in a woman above 45 with absent periods = postmenopausal. Perimenopause (the transition — ages $44\text{ to }52$ typically in Indian women): FSH $10\text{ to }40\text{ mIU/mL}$; irregular cycles; hot flashes; sleep disturbance; mood changes. Note: TSH must always be checked alongside FSH/LH in perimenopausal women — hypothyroidism causes identical symptoms (irregular periods, fatigue, mood changes, hair loss, weight gain) and is extremely common in Indian women above 40. 40s में: Day 2–3 FSH gradually rise। FSH >40 + absent periods 12 months = menopause। Perimenopause: FSH $10\text{ to }40$, irregular cycles, hot flashes। Always: TSH check करें साथ में — hypothyroidism identical symptoms causes (irregular periods, fatigue, mood changes) और 40+ Indian women में very common।
In contrast to high FSH from ovarian failure, hypothalamic amenorrhoea causes low FSH and low LH — the pituitary has stopped signalling because the hypothalamus has suppressed GnRH. Classic triad: absent/irregular periods + stress or underweight or excessive exercise. The female athlete triad: low energy availability (restrictive eating or high exercise expenditure) → hypothalamic GnRH suppression → low FSH/LH → anovulation → low oestrogen → bone loss (osteoporosis risk). In Indian urban women: chronic work stress + skipped meals + extreme dieting → hypothalamic amenorrhoea presenting exactly like PCOS but with low LH and FSH rather than high LH. The key distinguishing lab pattern: hypothalamic amenorrhoea: FSH low-normal ($2\text{ to }5$), LH low ($1\text{ to }3$); PCOS: FSH normal ($3\text{ to }8$), LH elevated ($8\text{ to }20$). Treatment under supervision: reduce stress, improve nutrition, reduce extreme physical stress — the axis recovers gradually. Hypothalamic amenorrhoea: Low FSH + Low LH (pituitary signal off — stress/underweight/exercise)। Indian urban women: work stress + dieting → looks like PCOS but LH और FSH दोनों low। Distinguishing: Hypothalamic = FSH low + LH low; PCOS = FSH normal + LH high। Treatment: stress reduce, nutrition improve, exercise reduce।
High Prolactin (Hyperprolactinaemia) — Causes & Treatment
Hyperprolactinaemia — elevated serum prolactin — is the most common pituitary disorder in reproductive-age women and a frequently missed cause of irregular periods and infertility in India. The key to interpretation: always rule out physiological causes and medication effects before investigating for a prolactinoma.
Hyperprolactinaemia = most common pituitary disorder in reproductive-age women। India में frequently missed cause of irregular periods और infertility। Key: physiological causes और medication effects rule out करें before prolactinoma investigate।| Prolactin Level (ng/mL) | Most Likely Cause in India | Next Step |
|---|---|---|
| $2\text{ to }29\text{ ng/mL}$ | Normal | No action needed. If symptoms persist, check other hormones. |
| $30\text{ to }60\text{ ng/mL}$ | Stress / anxiety during blood draw; hypothyroidism; sleep deprivation; dopamine-blocking medications (antipsychotics, metoclopramide, domperidone) | Repeat fasting morning prolactin after 30 min rest. Check TSH (hypothyroidism is the most common treatable cause). Review medications. |
| $60\text{ to }200\text{ ng/mL}$ | Microprolactinoma (small pituitary adenoma — most common); medications; hypothyroidism; renal failure | MRI pituitary (without contrast initially, then with). Confirm with repeat prolactin. Exclude hypothyroidism and medications first. |
| >$200\text{ ng/mL}$ | Macroprolactinoma (large pituitary tumour — above 10 mm) | Urgent MRI pituitary. Visual field assessment (tumour may compress optic chiasm). Endocrinology referral urgently. Start cabergoline or bromocriptine under specialist guidance. |
| Up to $> 300\text{ ng/mL}$ | Pregnancy (physiological) or lactation | Rule out pregnancy with serum beta-hCG before investigating elevated prolactin in any woman of reproductive age. |
- Domperidone (Dompéridone, Domstal) — the most widely used anti-nausea drug in India; a potent dopamine antagonist; commonly causes prolactin elevation to $60\text{ to }150\text{ ng/mL}$ when used regularly
- Metoclopramide (Perinorm, Emeset) — anti-emetic; same mechanism
- Antipsychotics (risperidone, haloperidol, chlorpromazine) — all potently elevate prolactin; patients on these drugs always have elevated prolactin
- Antidepressants (SSRIs — fluoxetine, sertraline; tricyclics) — milder elevation; important to note
- Ranitidine, cimetidine (H2 blockers — still used in India for acid reflux) — mild prolactin elevation
- Opiates / tramadol — raise prolactin; common pain medications in India
Rule: If a woman is on any of these medications and has elevated prolactin with symptoms — do NOT immediately MRI for prolactinoma. Withdraw or switch the medication for 4–6 weeks (under doctor's supervision), then recheck prolactin. If it normalises → medication was the cause, not a tumour.
Medications: Domperidone (Domstal — most common in India), Metoclopramide (Perinorm), Antipsychotics (risperidone, haloperidol), SSRIs (fluoxetine, sertraline), Ranitidine, Tramadol → सब prolactin elevate। Rule: medication पर elevated prolactin → 4–6 weeks medication withdraw/switch → recheck → normalise तो medication cause था, tumour नहीं।India Context — PCOS Epidemic & Stress Hormones
India में LH/FSH/Prolactin से related key clinical contexts:India has one of the world's highest PCOS prevalence rates ($15\%\text{ to }25\%$ of urban reproductive-age women). The drivers specific to Indian women: Insulin resistance — Indian women are genetically predisposed to insulin resistance at lower BMI ("thin-fat" phenotype — normal weight but high visceral fat); insulin stimulates ovarian androgen production (directly drives the LH-excess PCOS mechanism). Dietary pattern — high-refined-carbohydrate Indian diet (white rice, roti from refined flour, sweets) drives insulin spikes. Vitamin D deficiency — affects $70\%\text{ to }90\%$ of Indian women and impairs insulin sensitivity. Hypothyroidism — extremely common in Indian women ($1\text{ in }8$ above 40); elevates prolactin, disrupts menstrual cycles, and worsens insulin resistance — creating a PCOS-like picture. Always check TSH in any woman presenting with irregular periods before diagnosing PCOS. India में PCOS high prevalence drivers: Insulin resistance (genetic — thin-fat phenotype, visceral fat high at normal BMI); High-refined-carb diet (glucose spikes → insulin spikes → ovarian androgens); Vitamin D deficiency ($70\%\text{ to }90\%$); Hypothyroidism ($1\text{ in }8$ above 40 → prolactin raise + insulin resistance worsen)। Irregular periods → PCOS diagnose करने से पहले TSH check करें।
Chronic psychological and physiological stress is one of the most common and most overlooked causes of menstrual disruption in urban Indian women. The stress hormone cortisol (from adrenal glands) directly suppresses GnRH pulsatility at the hypothalamus → FSH and LH fall → anovulation → irregular periods. Simultaneously, cortisol stimulates prolactin release. The result: a stressed Indian working woman may have: irregular periods, mildly elevated prolactin ($30\text{ to }60\text{ ng/mL}$ — from stress, not prolactinoma), low-normal FSH and LH — a pattern that is often misdiagnosed as PCOS or investigated with expensive MRI. The clinical rule: always ask about life stressors, sleep quality, weight change, and exercise patterns before ordering hormonal tests — and always recheck prolactin in a calm, morning, fasting state before attributing mildly elevated prolactin to pathology. Chronic stress → cortisol → GnRH suppress → FSH + LH fall → anovulation + irregular periods + mildly elevated prolactin ($30\text{ to }60\text{ ng/mL}$ from stress, not prolactinoma)। Misdiagnosed as PCOS / expensive MRI। Rule: hormonal tests से पहले life stressors, sleep, weight change, exercise pattern पूछें। Mildly elevated prolactin: calm morning fasting state में recheck।
Test Preparation Checklist / टेस्ट की तैयारी
-
FSH and LH: Come on Day 2, 3, or 4 of your menstrual cycle — Day 1 = first day of FULL FLOW. This is non-negotiable. An FSH drawn on Day 10 reflects mid-follicular oestrogen suppression — it will appear falsely lower than the true basal value. An FSH drawn on Day 21 reflects the luteal phase — completely different from the basal value. The only informative time window for ovarian reserve and PCOS hormonal assessment is Days 2–4 of the cycle (the "basal" or "early follicular" measurement). FSH और LH: Cycle के Day 2, 3, या 4 पर। Day 1 = FULL FLOW का पहला दिन। Day 10 या 21 पर drawn FSH = completely different, interpretable नहीं। Only Days 2–4 = informative।
-
Prolactin: Morning collection, 2–3 hours after waking, between 8–11 AM. Prolactin follows a circadian rhythm — highest during sleep (peaks around 4–6 AM), then falls progressively through the day. The most stable and reproducible window is 2–3 hours after waking. An immediately post-waking draw (6 AM) gives falsely high prolactin. An afternoon draw (2–4 PM) gives unpredictably low prolactin. Always aim for the 8–11 AM window for prolactin. Prolactin: Morning collection — waking के 2–3 hours बाद, 8–11 AM। 6 AM = falsely high; 2–4 PM = unpredictably low। 8–11 AM window = most stable।
-
Prolactin: Rest for 20–30 minutes before blood draw — no rushing, no exercise, no breast stimulation. Prolactin is acutely stress-responsive. Rushing to the lab, waiting anxiously, having a difficult venepuncture, or exercising that morning raises prolactin $30\%\text{ to }50\%$ above baseline. Arrive at the lab 30 minutes early, sit quietly, and inform the phlebotomist you are having a prolactin test so they prioritise a calm, smooth collection. Breast stimulation within the preceding 24 hours also elevates prolactin significantly. Blood draw से 20–30 min पहले quietly rest। Rushing + anxiety + exercise = prolactin $30\%\text{ to }50\%$ raise। Lab में 30 min early arrive करें। Phlebotomist को inform करें (prolactin test है)। Breast stimulation 24 hours पहले avoid।
-
Disclose all medications — especially domperidone, metoclopramide, antipsychotics, and antidepressants. These are the most common causes of medically elevated prolactin in Indian women and are extremely widely prescribed. If you are on any of these medications, your prolactin will be elevated — it does not mean a pituitary tumour. Do not stop prescribed psychiatric medications for a blood test — instead, inform your gynaecologist and order a TSH and review the medication list before ordering an MRI. सभी medications बताएं: domperidone (Domstal — most common), metoclopramide (Perinorm), antipsychotics (risperidone, haloperidol), antidepressants (SSRIs)। इन पर elevated prolactin = pituitary tumour नहीं। Psychiatric medications test के लिए बंद नहीं — gynaecologist को inform करें।
-
Always order TSH alongside FSH/LH/Prolactin — hypothyroidism is the most common correctable cause of all three being abnormal. Under professional medical guidance, addressing thyroid function (e.g. tracking TSH) frequently helps support normal prolactin levels and reduces the metabolic stress that aggravates PCOS. Treating hypothyroidism alone often normalises prolactin, regularises periods, and improves PCOS symptoms — making it the single most important test to add. See our Thyroid guide. Always TSH add करें। Hypothyroidism: TRH rises → prolactin rise; insulin resistance worsen (PCOS aggravate)। Hypothyroidism treat करने से prolactin normalise, periods regularise, PCOS improve। 35+ Indian women में = most important add-on test।

For women interested in cycle tracking or supplementary lifestyle support, we have outlined two common options. Please note that dietary supplements and testing strips do not cure, treat, or replace professional medical treatment for diagnosed PCOS, thyroid disorders, or ovarian failure. Always consult your gynaecologist.
This kit offers home ovulation tracking strips that monitor LH levels in urine to help detect the standard mid-cycle rise. It is designed purely to help you identify your fertile window for planning intercourse or tracking cycles. persisting abnormal results should be checked by a specialist, as home strips are not diagnostic tools for underlying disorders. Note: LH strips test urine LH — not serum LH. Day 2–3 serum testing in a lab is a different measurement with distinct clinical meaning.

LH/FSH/Prolactin के साथ ये जांचें अक्सर order की जाती हैं:Frequently Asked Questions / अक्सर पूछे जाने वाले सवाल
FSH and LH must be drawn on Day 2, 3, or 4 of your menstrual cycle — with Day 1 being the first day of full red menstrual flow (not brown spotting or light spotting). This basal measurement, taken in the early follicular phase before significant follicle development, reflects the true resting pituitary signal — the most informative time point for assessing ovarian reserve (FSH) and PCOS pattern (LH:FSH ratio). If you come on Day 1 evening or Day 5+, the window is missed and the test cannot be meaningfully interpreted. For Prolactin and TSH: these can be drawn on any day of the cycle — always in the morning between 8–11 AM. For AMH: this can be drawn on any day of the cycle. If your periods are very irregular and you don't know when Day 2–3 will be: contact your gynaecologist's office — they may advise you to come on the first or second day of any bleed, or induce a bleed first with progesterone if periods are absent.
उत्तर: Day 2, 3, या 4 — Day 1 = FULL RED FLOW का पहला दिन (spotting नहीं)। Brown spotting = Day 1 नहीं। Day 5+ = window missed। Prolactin + TSH: any day, morning 8–11 AM। AMH: any day। Irregular periods: gynaecologist को call करें।An LH of $15\text{ mIU/mL}$ and FSH of $6\text{ mIU/mL}$ on Day 3 gives an LH:FSH ratio of $2.5:1$ — above the classic PCOS threshold of $2:1$. This is highly suggestive of PCOS but not diagnostic by itself. The current diagnostic standard for PCOS is the Rotterdam criteria — which requires at least 2 of these 3 criteria: (1) irregular or absent periods (oligo/anovulation); (2) clinical or biochemical signs of excess androgens (hirsutism, acne, hair loss, elevated testosterone); (3) polycystic ovarian morphology on ultrasound ($\ge 12$ follicles of $2\text{ to }9\text{ mm}$ per ovary, or ovarian volume above $10\text{ mL}$). An elevated LH:FSH ratio supports PCOS but must be correlated with these clinical findings, testosterone level (check free + total testosterone), AMH, fasting insulin, and HOMA-IR (70%+ of Indian PCOS patients have insulin resistance). PCOS should be confirmed by a gynaecologist — not diagnosed from a single blood test.
उत्तर: LH 15, FSH 6 → LH:FSH ratio $2.5:1$ (suggestive of PCOS)। लेकिन diagnosis = Rotterdam criteria — 3 में से 2: (1) Irregular periods; (2) Excess androgens (hirsutism/acne/high testosterone); (3) Polycystic ovaries on ultrasound। Lab alone से PCOS diagnose नहीं — gynaecologist से confirm करें।Not necessarily — and this is one of the most common over-investigations in India. A prolactin of $55\text{ ng/mL}$ (mildly elevated) should prompt a systematic evaluation before ordering MRI: (1) Recheck in a calm morning fasting state — stress, rushing, and needle anxiety can raise prolactin $30\%\text{ to }50\%$. A lab-reported 55 may be 35 on a calm recheck; (2) Check TSH — hypothyroidism is the most common correctable cause of elevated prolactin in Indian women; even mild TSH elevation ($5\text{ to }8\text{ mIU/L}$) can raise prolactin to $50\text{ to }80\text{ ng/mL}$; treating hypothyroidism normalises prolactin within 4–6 weeks; (3) Review all medications — are you taking domperidone (Domstal), metoclopramide, antipsychotics, or antidepressants? These routinely cause prolactin above $50\text{ ng/mL}$; (4) Rule out pregnancy with serum beta-hCG. If all these are excluded and prolactin remains above $50\text{ ng/mL}$ on two measurements — then MRI pituitary with gadolinium contrast is appropriate. A prolactin consistently above $100\text{ to }200\text{ ng/mL}$ with no other cause = prolactinoma likely, MRI essential.
उत्तर: Prolactin 55 = MRI immediately नहीं। First: (1) Calm morning fasting recheck; (2) TSH check (most common cause in India); (3) Medications review (domperidone, antipsychotics, antidepressants); (4) Pregnancy rule out (beta-hCG)। सब exclude → prolactin still >$50$ on 2 measurements → MRI pituitary। Prolactin >$100\text{ to }200$ consistently = prolactinoma likely।FSH of $18\text{ mIU/mL}$ on Day 3 at age 32 indicates significantly reduced ovarian reserve — higher than expected for your age. This means your pituitary is working harder (producing more FSH) to stimulate an ovary that has fewer and/or lower-quality follicles remaining. Practically this means: (1) Your fertility window may be shorter than average — you may have fewer years before fertility declines significantly; (2) If you are planning IVF, you may respond more poorly to ovarian stimulation than someone with FSH of 6 — fewer eggs retrieved per cycle; (3) FSH fluctuates cycle-to-cycle — a single high reading should be confirmed on at least one repeat measurement. Complement with an AMH level (which gives a more stable estimate of ovarian reserve — available any day of cycle). A high FSH with low AMH together paint a clearer picture. This finding does NOT mean you cannot conceive — many women with FSH $15\text{ to }20\text{ mIU/mL}$ conceive naturally or with IVF. However, it warrants urgent consultation with a reproductive endocrinologist, especially if you are planning to start a family. Do not delay.
उत्तर: FSH 18 at age 32 = significantly reduced ovarian reserve for age। Implications: Shorter fertility window; Poor IVF response; FSH fluctuates — confirm on repeat। AMH level add करें (any day, more stable)। High FSH + Low AMH = clearer picture। Conceive possible है — लेकिन reproductive endocrinologist से urgent consultation। Delay नहीं।Both PCOS and hypothyroidism cause irregular periods and weight gain — and the two conditions frequently coexist in Indian women (thyroid dysfunction is more common in women with PCOS, and vice versa). The only way to distinguish them is through testing. Check both simultaneously: Day 2–3 LH, FSH, testosterone, AMH (PCOS evaluation) + TSH, free T3, free T4 (thyroid evaluation). Clues that favour hypothyroidism over PCOS: hair loss (especially from the outer third of eyebrows), cold intolerance, dry skin, severe fatigue disproportionate to activity, constipation, and slow heart rate. Clues that favour PCOS: facial and body hair (hirsutism), acne, oily skin, difficulty conceiving, and ultrasound showing polycystic ovaries. However: many women have both. Treating hypothyroidism first (with levothyroxine) sometimes resolves the irregular periods completely — meaning PCOS was a secondary phenomenon driven by thyroid disruption. Always check TSH before concluding PCOS.
उत्तर: Both PCOS और hypothyroidism = irregular periods + weight gain। दोनों Indian women में coexist करते हैं। Testing: Day 2–3 LH/FSH/Testosterone/AMH + TSH/T3/T4। Hypothyroidism clues: eyebrow hair loss, cold intolerance, dry skin, constipation। PCOS clues: hirsutism, acne, oily skin, polycystic ovaries। Hypothyroidism treat करने से periods regularise हो सकती हैं। TSH check करें PCOS conclude करने से पहले।No — PCOS is one of the most treatable causes of infertility. Most women with PCOS can conceive with appropriate management. PCOS causes anovulatory infertility — meaning the problem is not with the egg quality or the uterus, but simply that ovulation is not occurring regularly. Clinical strategies under gynecological supervision focus on: (1) Structured lifestyle changes — weight management of just $5\%\text{ to }10\%$ of body weight in overweight PCOS patients can help restore spontaneous cyclic rhythms; (2) Metabolic support — improving underlying insulin resistance to naturally balance endocrine pathways; (3) Targeted medical induction — utilizing physician-prescribed clomiphene citrate or letrozole when trying to conceive; (4) Advanced reproductive assistance (IVF) — for resistant cases, managed under strict specialist monitoring.
उत्तर: नहीं — PCOS most treatable causes of infertility में। Problem = anovulation (ovulation नहीं होती), egg या uterus नहीं। Treatment: 1. Lifestyle modification ($5\%\text{ to }10\%$ weight loss → 55–60% ovulation restore)। 2. Metformin (insulin resistance improve)। 3. Letrozole (first-line ovulation induction — India में clomiphene से better)। 4. Clomiphene। 5. IVF (OHSS risk से careful monitoring)।- FOGSI (Federation of Obstetric and Gynaecological Societies of India): FOGSI — PCOS Clinical Guidelines & Women's Reproductive Health Resources

This article is for educational purposes only. LH, FSH, and Prolactin results must be interpreted by a qualified gynaecologist or reproductive endocrinologist alongside clinical symptoms, physical examination, ultrasound, TSH, testosterone, and AMH. Never self-diagnose PCOS, prolactinoma, or premature ovarian failure from lab values alone. A mildly elevated prolactin almost always has a benign or reversible cause — do not panic or order an MRI without first ruling out stress, hypothyroidism, and medications.
यह लेख केवल शैक्षिक है। Results को gynaecologist से clinical symptoms + ultrasound + TSH + testosterone + AMH के साथ interpret करवाएं। Lab values से self-diagnose PCOS, prolactinoma, या POI नहीं। Mildly elevated prolactin: stress, hypothyroidism, medications rule out करें पहले — panic नहीं, MRI immediately नहीं।
