What is the role of the Luteinizing Hormone (LH) in the body?

Luteinizing Hormone (LH) plays a crucial role in the reproductive system of both males and females. In females, LH is responsible for triggering ovulation, which is the process where an egg is released from the ovary. This surge of LH is essential for the menstrual cycle and is a key driver of fertility. In males, LH stimulates the production of testosterone in the Leydig cells of the testes, which is vital for the development of male secondary sexual characteristics, sperm production, and overall reproductive health.

The functions of LH highlight its importance in regulating the reproductive hormones and processes, making it central to fertility and sexual health. The other choices refer to unrelated physiological functions that do not involve LH, reinforcing the understanding that LH is primarily associated with reproductive roles.
