What hormone contributes to sperm production in males and is released by the anterior pituitary gland?

The hormone that contributes to sperm production in males and is released by the anterior pituitary gland is Follicle Stimulating Hormone (FSH). FSH plays a crucial role in the regulation of the male reproductive system. It stimulates Sertoli cells in the testes, which are essential for the process of spermatogenesis. Sertoli cells support and nourish developing sperm cells, thereby facilitating the production of mature sperm.

In males, FSH is integral to the formation of sperm, helping to maintain proper male fertility. It works alongside testosterone, which is also necessary for sperm development. The anterior pituitary gland is responsible for producing and releasing FSH in response to signals from the hypothalamus, specifically gonadotropin-releasing hormone (GnRH), illustrating the hormone's role in the endocrine signaling pathway that regulates reproductive functions in males.

The other hormones mentioned do not have the same direct role in sperm production. Leptin is primarily involved in regulating energy balance and metabolism, ghrelin is known for its role in stimulating appetite, and prolactin primarily influences lactation and may have roles in fertility and reproductive health, but it does not directly stimulate sperm production as FSH does.
