Final answer:
Follicle-stimulating hormone (FSH) is responsible for stimulating gamete production in both males and females, crucial for reproductive processes.
Step-by-step explanation:
The hormone that stimulates gamete (sperm or egg) production is the follicle-stimulating hormone (FSH). FSH is produced by the anterior pituitary gland and plays a critical role in the reproductive system by regulating the development, growth, pubertal maturation, and reproductive processes of the body. In males, FSH stimulates the maturation of sperm cells, while in females, it promotes the maturation of ovarian follicles, eventually leading to ovulation.
