Hypophysectomy results in

Options

A. Heart attack
B. Regression of reproductive functions
C. Death
D. Poor digestion.

Answer

### Step-by-Step Solution:

1. **Understanding Hypophysectomy**:
- Hypophysectomy refers to the surgical removal of the pituitary gland, which is also known as the hypophysis.

2. **Role of the Pituitary Gland**:
- The pituitary gland is crucial for regulating various bodily functions. It secretes several hormones, including Luteinizing Hormone (LH) and Follicle Stimulating Hormone (FSH), which are vital for reproductive functions.

3. **Effects of Removing the Pituitary Gland**:
- When the pituitary gland is removed, the secretion of LH and FSH stops. These hormones are essential for the growth of ovarian follicles in females and for spermatogenesis in males.

4. **Consequences of Hormonal Deficiency**:
- The absence of LH and FSH leads to a regression of reproductive functions. This means that the processes related to reproduction, such as the development of eggs in females and sperm production in males, will be adversely affected.

5. **Elimination of Other Options**:
- The removal of the pituitary gland does not directly cause a heart attack, death, or poor digestion. The primary impact is on reproductive functions due to the lack of key hormones.

6. **Conclusion**:
- Therefore, the correct answer to the question "Hypophysectomy results in" is **regression of reproductive functions**.
