Final answer:
Follicle-stimulating hormone (FSH) in males functions in the development of male gonads and the release of factors that concentrate testosterone.
Step-by-step explanation:
In males, follicle-stimulating hormone (FSH) stimulates the maturation of sperm cells, while luteinizing hormone (LH) stimulates the production of the sex hormones or androgens such as testosterone. Therefore, the function of follicle-stimulating hormone in males is the development of male gonads and the release of factors that concentrate testosterone.
