Cells of Leydig are associated with the secretion of

Options

A. Progesterone
B. Testosterone
C. Prolactin
D. Estrogen

Answer

**Step-by-Step Solution:**

1. **Identify the Cells of Leydig**: The question asks about the cells of Leydig, which are also known as interstitial cells found in the testes.

2. **Understand Their Function**: Leydig cells are primarily responsible for the production of hormones. They play a crucial role in male reproductive physiology.

3. **Identify the Hormones Secreted**: The main hormone secreted by Leydig cells is testosterone, which is an androgen (male sex hormone).

4. **Differentiate from Other Hormones**: The question provides options including progesterone, prolactin, and estrogen.
- Progesterone and estrogen are hormones associated with female reproductive functions and are produced in the ovaries.
- Prolactin is produced by the pituitary gland and is involved in milk production.

5. **Conclude the Correct Answer**: Since Leydig cells are associated with the secretion of testosterone, the correct answer is testosterone.

**Final Answer**: Cells of Leydig are associated with the secretion of testosterone.
