What is one of the main functions of Luteinizing hormone (LH)?

  1. It stimulates adrenal corticosteroid production

  2. It promotes uterine contraction

  3. It facilitates ovulation and testosterone synthesis

  4. It inhibits growth hormone secretion

The correct answer is: It facilitates ovulation and testosterone synthesis

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 release of an egg from the ovary. This process is vital for reproduction and is part of the menstrual cycle. Additionally, LH stimulates the ovaries to produce progesterone, which is important for preparing the endometrium for a potential pregnancy. In males, LH has the function of promoting testosterone synthesis in the testes. Testosterone is essential for the development of male secondary sexual characteristics, spermatogenesis, and overall reproductive health. Overall, LH is integral to the regulation of reproductive hormones and processes, making it essential for both ovulation and testosterone production, which is why this option is the correct choice.
