Androgens are produced by 

Options

A. Pituitary
B. Parathyroid
C. Thyroid
D. Adrenals.

Answer

**Step-by-Step Solution:**

1. **Understanding Androgens**: Androgens are a group of hormones that play a role in male traits and reproductive activity. The most well-known androgen is testosterone.

2. **Source of Androgens**: The primary source of androgens, particularly testosterone, is the Leydig cells located in the testes. These cells are responsible for the production of testosterone in males.

3. **Additional Source**: Besides the testes, androgens are also produced by the adrenal glands, specifically in the adrenal cortex. The adrenal glands are located on top of the kidneys and consist of two parts: the cortex and the medulla.

4. **Functions of Androgens**: Testosterone, as a major androgen, is crucial for several functions:
- It promotes spermatogenesis (the formation of sperm).
- It is responsible for the development of secondary sexual characteristics in males during puberty, such as the growth of facial and body hair, deepening of the voice, and changes in sexual behavior.

5. **Conclusion**: Therefore, the correct answer to the question "Androgens are produced by" is that they are produced by the Leydig cells in the testes and the adrenal cortex.

**Final Answer**: Androgens are produced by the Leydig cells of the testes and the adrenal cortex.
