In males, FSH __________.

• A. is not produced; it is a female hormone
• B. is directly responsible for facial hair growth beginning at puberty
• C. regulates Leydig cells and thus the secretion of androgens
• D. stimulates the release of semen by the prostate gland during ejaculation
• E. stimulates development of sperm cells in the testes

Answer: (E)

Verified step by step guidance

1. Understand the role of FSH (Follicle Stimulating Hormone) in the male reproductive system. FSH is a hormone produced by the anterior pituitary gland and plays a crucial role in the development and function of the testes.
2. Recognize that FSH is not exclusive to females; it is also important in males for reproductive functions.
3. Identify the primary function of FSH in males, which is to stimulate the Sertoli cells in the testes. Sertoli cells are essential for the process of spermatogenesis, which is the development of sperm cells.
4. Clarify that FSH does not directly regulate Leydig cells or androgen secretion. Leydig cells are regulated by LH (Luteinizing Hormone), which stimulates the production of testosterone.
5. Note that FSH is not involved in the release of semen during ejaculation. This process is primarily controlled by the autonomic nervous system and involves other factors such as muscle contractions.
