What kind of test is FSH and LH?

FSH (Follicle-Stimulating Hormone) and LH (Luteinizing Hormone) tests are blood tests that measure the levels of these hormones produced by the pituitary gland. They are often used to assess reproductive health, evaluate menstrual irregularities, and diagnose conditions such as polycystic ovary syndrome (PCOS) or pituitary disorders. The results can help determine ovarian function in women and testosterone production in men.
