Question

Sertoli cells are controlled by which of the following hormones?

• A. LH
• B. FSH
• C. Prolactin
• D. GH

Hint:

FSH is crucial for spermatogenesis as it activates Sertoli cells to nurture sperm development.

Answer 1

The Correct Option is B

Step 1: Understand Sertoli cells.
Sertoli cells are the supporting cells of the seminiferous tubules in the testes. They play an essential role in spermatogenesis.
Step 2: Review the options.
- LH (Luteinizing Hormone) stimulates Leydig cells to produce testosterone but does not directly control Sertoli cells.
- FSH (Follicle Stimulating Hormone) stimulates Sertoli cells to support and nourish developing sperm, making it the correct hormone for controlling Sertoli cells.
- Prolactin is involved in milk production and lactation, not in controlling Sertoli cells.
- GH (Growth Hormone) influences overall growth but does not have a direct role in Sertoli cell function.
Step 3: Conclude.
FSH directly controls Sertoli cells, making option (B) the correct answer.
Final Answer: \[ \boxed{\text{FSH}} \]
