LH (Luteinizing Hormone)
LH is a pituitary hormone that triggers ovulation in women and stimulates testosterone production by Leydig cells in men. The mid-cycle LH surge drives ovulation, and persistent elevation of LH relative to FSH can suggest polycystic ovary syndrome. Elevated LH in postmenopausal women reflects ovarian failure, while low LH suggests hypothalamic or pituitary dysfunction.
Optimal range: who says what
No institution or named practitioner we track states an optimal target for LH (Luteinizing Hormone). How we verify ranges.
- General guidance, no named sourcePhase-appropriateNo single optimal; the mid-cycle surge is the functional signal
- Lab reference intervalFollicular: 2.4-12.6 mIU/mL, Mid-cycle: 14.0-95.6 mIU/mL, Luteal: 1.0-11.4 mIU/mLWhat a lab report flags against. A lab interval is not an optimal target.

Why LH (Luteinizing Hormone) matters
Triggers ovulation and corpus luteum formation. LH surge indicates imminent ovulation. Abnormal levels indicate PCOS or pituitary disorders.
