Final answer:
1) FSH stimulates the production of sperm cells in the testes and LH stimulates the production of testosterone in the testes. FSH stimulates the maturation of sperm cells in the testes, while LH is responsible for stimulating the production of testosterone by the interstitial cells of the testes.
Step-by-step explanation:
The role of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) is crucial in regulating the male reproductive system, specifically during the process of spermatogenesis and testosterone production. In males, FSH primarily stimulates the maturation of sperm cells within the testes, working alongside Sertoli cells that are essential for this process. However, the production of FSH can be inhibited by the hormone inhibin, which is released by the testes when there is sufficient sperm production.
On the other hand, LH plays a key role in stimulating the production of sex hormones, particularly testosterone, through its action on the interstitial cells of Leydig in the testes. The increase in testosterone levels, driven by LH, contributes to secondary sexual characteristics such as deeper voice and increased muscle mass, in addition to its foundational support for sperm production and maturation.
Therefore, the correct statement regarding the roles of FSH and LH in the male reproductive system is: 1) FSH stimulates the production of sperm cells in the testes and LH stimulates the production of testosterone in the testes.
