What is the function of luteinizing hormone (LH)?

Luteinizing hormone (LH) plays a crucial role in the reproductive system. It is produced by the anterior pituitary gland and is essential for both male and female reproductive health. In females, LH triggers ovulation, which is the release of an egg from the ovary. This surge in LH is a critical part of the menstrual cycle and signals the body to prepare for potential fertilization.

In males, LH stimulates the Leydig cells in the testes to produce testosterone, the primary male sex hormone. Testosterone is important for the development of male secondary sexual characteristics, sperm production, and overall male reproductive function.

Thus, the function of LH encompasses both triggering ovulation in females and stimulating testosterone production in males, making the selected answer accurate in capturing the dual role of this hormone in the endocrine system.
