What hormone plays a key role in stimulating the production of sperm in males?

The hormone that is pivotal in stimulating the production of sperm in males is Follicle-stimulating hormone (FSH). FSH is produced by the pituitary gland and acts on the Sertoli cells in the testes, which are crucial for the process of spermatogenesis. These cells support the maturation of sperm and help regulate the factors necessary for sperm production.

Under the influence of FSH, Sertoli cells create an environment that is conducive to the development of sperm. This hormone plays a vital role not only in the initiation of sperm production but also in maintaining the overall health and function of the sperm-producing cells.

While testosterone is also important for male reproductive health, as it drives the development of male secondary sexual characteristics and is essential for the final stages of sperm maturation, it does not directly stimulate the production of sperm. Luteinizing hormone (LH) is more critical for stimulating testosterone production rather than sperm production. Estrogen, while present in males, does not play a direct role in stimulating sperm production.
