What does a high LH mean?
Short answer
High LH is expected briefly at ovulation and permanently after menopause. Outside those, an LH higher than FSH in a woman with irregular cycles is a classic (though not required) PCOS finding; high LH with high FSH indicates ovarian insufficiency. In men, high LH means the testes are failing to respond (primary hypogonadism).

What is the normal range for LH?
- Male, age 18+: 1.70 – 8.60 mIU/mL

In women, often reflects menopause or PCOS. In men, can reflect testicular issues.

Common questions
Does a high LH:FSH ratio prove PCOS?
No — it supports the diagnosis but isn't required or specific. PCOS is diagnosed on cycle history, androgen signs or levels, and ultrasound.
