What hormone stimulates the production of reproductive cells in the gonads?

Follicle-stimulating hormone (FSH) plays a crucial role in the reproductive system, particularly in the stimulation of gametogenesis, which is the process of producing reproductive cells. In males, FSH is essential for the production of sperm in the testes, while in females, it stimulates the growth and maturation of ovarian follicles, which ultimately leads to the production of eggs (oocytes).

This hormone acts primarily on the Sertoli cells in males and on the granulosa cells in females, fostering the environment necessary for the development of mature gametes. The specificity of FSH in targeting these cells highlights its significance in promoting reproductive health and fertility, making it a key player in the endocrine regulation of reproduction.

In contrast, other hormones mentioned, while also tied to reproduction, have different primary functions. Testosterone is primarily responsible for the development of male secondary sexual characteristics and the maintenance of male reproductive tissues. Luteinizing hormone (LH) triggers ovulation and stimulates testosterone production, but it does not directly stimulate the production of the reproductive cells themselves. Progesterone plays a critical role in preparing the uterus for implantation of an embryo and maintaining pregnancy but does not have a direct role in gametogenesis. Thus, FSH is correctly
