What is the function of Luteinizing hormone (LH)?

Luteinizing hormone (LH) plays a crucial role in the reproductive system, particularly in regulating the functions of the ovaries and testes. In females, LH is responsible for triggering ovulation and stimulating the production of progesterone from the corpus luteum after ovulation. This hormone ensures the proper functioning of the menstrual cycle and the maintenance of the early stages of pregnancy.

In males, LH stimulates the Leydig cells in the testes to produce testosterone, which is essential for sperm production and the development of male secondary sexual characteristics. Thus, the primary function of LH is to support and regulate reproductive processes in both genders, making it directly involved in gamete production and the overall functioning of the reproductive system.
