If spermatogenesis proceeds rapidly, inhibin is released. Inhibin reduces secretion of

Options

A. Luteinizing hormone
B. Follicle stimulating hormone
C. Testerone
D. Interstitial cell stimulating hormone.

Answer

**Step-by-Step Solution:**

1. **Understanding Spermatogenesis**: Spermatogenesis is the process by which sperm cells are produced in the male reproductive system. It occurs in the seminiferous tubules of the testes.

2. **Role of Inhibin**: Inhibin is a hormone produced by Sertoli cells in the testes. Its primary function is to regulate the production of sperm by providing feedback to the pituitary gland.

3. **Feedback Mechanism**: When spermatogenesis is proceeding rapidly, the levels of inhibin increase. This increase serves as a signal to the pituitary gland to reduce the secretion of certain hormones.

4. **Identifying the Target Hormone**: The key hormone that is affected by inhibin is Follicle-Stimulating Hormone (FSH). FSH is responsible for stimulating the Sertoli cells and promoting spermatogenesis.

5. **Conclusion**: Since inhibin reduces the secretion of FSH from the pituitary gland, the correct answer to the question is **B. Follicle-Stimulating Hormone**.
