FSH drives follicle development in the ovary and sperm production in the testis. A day 2–5 blood test is sometimes used alongside AMH to assess ovarian reserve: a high early-cycle FSH suggests the ovaries need more signal to respond. Levels fluctuate between cycles, so one result is interpreted in context, not alone.
Also known as: follicle stimulating hormone, follicle-stimulating hormone
