Final answer:
Leydig cells are responsible for the production of testosterone, which is stimulated by luteinizing hormone (LH) from the pituitary gland. FSH affects the Sertoli cells and is not involved in testosterone synthesis by Leydig cells.
Step-by-step explanation:
When educating adolescents on male hormone production, it is important to note that Leydig cells are responsible for producing testosterone. Testosterone is a steroid hormone crucial for male development and reproductive function. The production of testosterone by Leydig cells is regulated by luteinizing hormone (LH) released from the pituitary gland. This process is initiated by the hypothalamus that secretes gonadotropin-releasing hormone (GnRH), which in turn stimulates the anterior pituitary gland to release LH. LH then binds to receptors on Leydig cells, triggering them to synthesize and secrete testosterone. In contrast, follicle-stimulating hormone (FSH) acts predominantly on Sertoli cells to support spermatogenesis.
