The secretion of follicle stimulating hormone from the Pituitary is reduced by

Options

A. inhibin
B. luteinizing hormone
C. oxytocin
D. prolactin

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks which factor reduces the secretion of follicle stimulating hormone (FSH) from the pituitary gland.

2. **Identifying the Source of FSH**: Follicle stimulating hormone (FSH) is secreted by the anterior pituitary gland. It plays a crucial role in reproductive processes, including sperm production in males and follicle maturation in females.

3. **Exploring the Options**: The options provided are:
- Option 1: Inhibin
- Option 2: Luteinizing Hormone (LH)
- Option 3: Oxytocin
- Option 4: Prolactin

4. **Analyzing the Role of Inhibin**: Inhibin is a hormone that is produced in both males and females. In males, it is secreted by Sertoli cells, and in females, it is secreted by granulosa cells. Inhibin specifically functions to inhibit the secretion of FSH from the anterior pituitary gland.

5. **Evaluating Other Options**:
- **Luteinizing Hormone (LH)**: While LH works alongside FSH in reproductive functions, it does not directly reduce FSH levels.
- **Oxytocin**: This hormone is primarily involved in childbirth and lactation, with no direct role in regulating FSH.
- **Prolactin**: Although it plays a role in milk production, it does not have a direct effect on FSH secretion.

6. **Conclusion**: Based on the analysis, the hormone that reduces the secretion of FSH from the pituitary gland is **Inhibin** (Option 1).

### Final Answer:
The secretion of follicle stimulating hormone from the pituitary is reduced by **Inhibin** (Option 1).
