What is the primary function of FSH in the male reproductive system?

The primary function of FSH, or Follicle Stimulating Hormone, in the male reproductive system is to stimulate sperm production. In males, FSH acts on the Sertoli cells located in the seminiferous tubules of the testes. These Sertoli cells support and nourish developing sperm cells during the process of spermatogenesis. By promoting the maturation of sperm, FSH plays a crucial role in male fertility.

While testosterone secretion is indeed important for male reproductive health, it is primarily stimulated by another hormone called LH (Luteinizing Hormone). The other options mentioned, such as egg maturation and uterine growth, are related to female reproductive processes and are not applicable to the male reproductive system. This focus on FSH's role in sperm production highlights its critical function in male reproductive health and the overall process of reproduction.
