Final answer:
FSH and LH from the pituitary gland regulate the male reproductive system by stimulating sperm maturation and testosterone production. They are part of a hormonal feedback loop involving inhibin and testosterone, ensuring proper reproductive function.
Step-by-step explanation:
The hormones follicle-stimulating hormone (FSH) and luteinizing hormone (LH), produced by the pituitary gland, play a crucial role in the regulation of the reproductive system. In males, FSH and LH stimulate the testes to produce sperm and testosterone, respectively. FSH is responsible for the maturation of sperm cells and is regulated by the hormone inhibin, which is released by the testes when the sperm count is sufficient. On the other hand, LH, also known as interstitial cell-stimulating hormone, promotes the production of testosterone by the Leydig cells within the testes.
The hypothalamus produces gonadotropin-releasing hormone (GnRH), which signals the pituitary to release FSH and LH. This release is part of a feedback system involving testosterone and inhibin levels, which ensures the proper function of the male reproductive system. Testosterone is crucial for the development of male secondary sexual characteristics, such as muscular build and body hair, and is also imperative for maintaining libido and general health.
