What is the primary function of Luteinizing Hormone (LH)?

Luteinizing Hormone (LH) plays a crucial role in reproductive physiology. Its primary function is to trigger ovulation in females and stimulate the production of testosterone in males. In females, LH surges mid-cycle to lead to the release of an egg from the ovary, a process vital for fertility. In males, LH prompts the testes to produce testosterone, which is essential for sperm production and the development of male secondary sexual characteristics. This dual role in both sexes highlights LH's significance in regulating reproductive functions, making the choice that identifies its involvement in ovulation and testosterone production correct.
