Key hormone for ovulation and reproductive function — helps evaluate fertility in both sexes. Luteinizing Hormone (LH) triggers ovulation in women and stimulates testosterone production in men. In women, the LH surge mid-cycle signals the release of an egg. Testing LH levels helps evaluate fertility, irregular periods, and menopause. In men, LH testing can help identify causes of low testosterone. The LH:FSH ratio is also used to evaluate conditions like PCOS. **Clinical use:** Luteinizing Hormone — pituitary hormone that triggers ovulation in women and stimulates testosterone production in men. Used in fertility workup, menopause assessment, and hypogonadism evaluation. ## Who should order it? Women with irregular cycles, infertility, suspected PCOS or menopause; men with low testosterone, infertility, or hypogonadism workup; anyone evaluating pituitary function. ## Biomarkers measured - [LH](https://www.test-well.com/biomarkers/lh) ## Price by lab | Lab | Test price | All-in (with $6 fee) | Notes | | --- | --- | --- | --- | | Quest Diagnostics | $36.99 | $42.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | | Labcorp | $36.99 | $42.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | | BioReference (NY & NJ) | $33.99 | $39.99 | New York and New Jersey orders route here automatically | Rhode Island is not served.

Both are pituitary hormones acting on the gonads. [FSH](https://www.test-well.com/tests/fsh) stimulates egg/sperm development. LH triggers ovulation (women) and testosterone production (men). They're almost always ordered together because the ratio matters: elevated LH:FSH ratio (>2:1) is a classic PCOS sign. ### When in my cycle should I test LH? Day 3 of your cycle for baseline / ovarian-reserve evaluation, paired with [FSH](https://www.test-well.com/tests/fsh) and [Estradiol](https://www.test-well.com/tests/estradiol). Mid-cycle (day 12-16) for ovulation detection — LH surges 24-36 hours before ovulation. Random LH is useful for menopause confirmation (>30 mIU/mL). ### What's a normal LH level? Reproductive-age women, day 3: 1-12 mIU/mL. Mid-cycle surge: up to 100 mIU/mL. Menopausal: 16-66 mIU/mL. Men: 1.7-8.6 mIU/mL. Children before puberty: under 5 mIU/mL. ### What does the LH:FSH ratio tell me? Day-3 LH:FSH ratio >2:1 is a classic finding in PCOS. Equal or higher FSH than LH in a woman of reproductive age suggests diminished ovarian reserve or perimenopause. In men, both being low suggests pituitary dysfunction; both being high suggests primary testicular failure. ### How much does an LH test cost without insurance? On TestWell, LH is $36.99. Quest Direct lists the same test at $49, walk-in hospital labs typically bill $100-140 without insurance. ### What is the CPT code for LH? The CPT code for Luteinizing Hormone is 83002. [FSH](https://www.test-well.com/tests/fsh) (almost always ordered alongside) is 83001. ### Should I bundle LH with other fertility hormones? Yes. The standard fertility workup includes day-3 LH + [FSH](https://www.test-well.com/tests/fsh) + [Estradiol](https://www.test-well.com/tests/estradiol) + [AMH](https://www.test-well.com/tests/amh) + [Prolactin](https://www.test-well.com/tests/prolactin) + [TSH](https://www.test-well.com/tests/tsh).
