This test measures the amount of Luteinizing Hormone (LH) in the blood. LH is a hormone produced by the pituitary gland. In women, LH stimulates ovulation as well as the production of estradiol and progesterone. In men, LH stimulates the production of testosterone. Measuring Luteinizing Hormone can be useful is evaluating the cause of infertility or aiding in the diagnosis of disorders affecting the pituitary, ovaries or testicles. In children, measuring LH can help determine the cause for early or delayed puberty.
This test is typically ordered for men or women who are having difficulty conceiving or are experiencing symptoms of a pituitary disorder. LH is often done along with other blood tests such as FSH, Estradiol, Testosterone or Progesterone.
