Answer:
D. FSH and androgens
Read Explanation:
Spermatogenesis is a complex process regulated by two key hormones: FSH (Follicle-Stimulating Hormone) and androgens, primarily testosterone.
Role of Hormones in Spermatogenesis
Follicle-Stimulating Hormone (FSH): Produced by the pituitary gland, FSH stimulates the Sertoli cells in the testes. Sertoli cells are crucial because they provide the structural support and nutrients necessary for the developing sperm cells. FSH ensures the survival and proliferation of spermatogonia (the precursor cells of sperm).
Luteinizing Hormone (LH): While not directly regulating spermatogenesis, LH stimulates the Leydig cells to produce testosterone, which is essential for the process.
Androgens (Testosterone): Produced primarily by the Leydig cells in the testes in response to LH, testosterone acts on the Sertoli cells to promote the final maturation and development of sperm. It is absolutely necessary for the completion of meiosis in spermatocytes and the process of spermiogenesis, which transforms spermatids into mature sperm.
The combined action of FSH and testosterone is critical for the proper and efficient production of sperm.
