All the following are the features of inhibin hormone , except :

Options

A. Its secretion increases with increase in the number of spermatozoa .
B. It stimulates FSH secretion in males
C. It is secreted by sertoli cells
D. It is a non-steroidal hormone .

Answer

To solve the question regarding the features of the inhibin hormone, we will analyze each of the provided statements and determine which one does not accurately describe the hormone.

### Step-by-Step Solution:

1. **Understanding Inhibin Hormone**:
- Inhibin is a hormone produced primarily in the gonads (testes in males and ovaries in females). Its main role is to regulate the production of follicle-stimulating hormone (FSH) from the anterior pituitary gland.

2. **Analyzing Each Statement**:
- **Statement 1**: "Its secretion increases with an increase in the number of spermatozoa."
- This statement is **true**. Inhibin levels rise in response to increased sperm production to help regulate FSH levels.

- **Statement 2**: "It stimulates FSH secretion in males."
- This statement is **false**. Inhibin actually inhibits FSH secretion, so this option is the correct answer to the question as it does not describe a feature of inhibin.

- **Statement 3**: "It is secreted by the Sertoli cells."
- This statement is **true**. Sertoli cells in the testes produce inhibin.

- **Statement 4**: "It is a non-steroidal hormone."
- This statement is **true**. Inhibin is classified as a non-steroidal hormone.

3. **Conclusion**:
- The only statement that does not correctly describe the features of inhibin hormone is **Statement 2**: "It stimulates FSH secretion in males." Therefore, this is the answer to the question.

### Final Answer:
The correct answer is: **It stimulates FSH secretion in males.**
