In males,the spermatogenesis is regulated by

Options

A. FSH
B. androgens
C. Both (1) and (2)
D. Hypothalamus

Answer

**Step-by-Step Solution:**

1. **Understanding Spermatogenesis**: Spermatogenesis refers to the process of sperm formation in males. It is crucial to understand what this term means before identifying the regulators involved.

2. **Identifying the Key Hormone**: The primary hormone that regulates spermatogenesis is Follicle Stimulating Hormone (FSH). This hormone plays a significant role in the development and maturation of sperm cells.

3. **Source of FSH**: FSH is secreted by the anterior lobe of the pituitary gland. This gland is located at the base of the brain and is responsible for releasing various hormones that regulate different bodily functions.

4. **Evaluating Other Options**:
- **Androgens**: These are male sex hormones, primarily testosterone, which are secreted from the adrenal gland (specifically the adrenal cortex). While androgens are important for the development of male secondary sexual characteristics, they do not directly regulate spermatogenesis.
- **Combination of FSH and Androgens**: The option that states both FSH and androgens is not correct in the context of direct regulation of spermatogenesis.
- **Hypothalamus**: The hypothalamus secretes hormones like ADH (antidiuretic hormone) and oxytocin, which do not have a direct role in spermatogenesis.

5. **Conclusion**: After evaluating all the options, the correct answer to the question is FSH (Follicle Stimulating Hormone) since it is the primary hormone regulating the process of spermatogenesis in males.

**Final Answer**: FSH (Follicle Stimulating Hormone)
