About Luteinising Hormone (LH)

Luteinising hormone (LH) is produced by the pituitary gland in the brain.

In women, the levels of LH are dependent on estradiol levels, which are produced by the follicles that contain the eggs. As follicles grow and eggs mature, a certain threshold of estradiol is reached and a signal is sent to the pituitary gland to increase LH production. A peak of LH is responsible for the final stage of egg maturation and its release from the ovary after 48 hours. In men, LH hormone stimulates the Leydig cells in the testes to produce testosterone.
