The ……………X……………cells of testes, which are present inside the seminiferous tubule of testes synthesize and secretes …………Y…………. hormones .
Choose the correct option for X and Y.

Options

A. X : Leyding , Y : Androgens
B. X : Interstitial , Y : Testicular
C. X : Sertoli , Y : Inhibin B
D. Both (a) and (b)

Answer

To solve the question, we need to identify the correct cells (X) in the testes that synthesize and secrete a specific hormone (Y). Here’s a step-by-step breakdown of the solution:

### Step 1: Identify the cells present in the seminiferous tubules of the testes.
- The seminiferous tubules contain two main types of cells: spermatogonia and Sertoli cells.

### Step 2: Determine the function of each type of cell.
- **Spermatogonia**: These are male germ cells that develop into sperm. They do not synthesize hormones.
- **Sertoli cells**: These cells provide nourishment to developing sperm and are involved in the regulation of spermatogenesis. They also synthesize hormones.

### Step 3: Identify the hormone secreted by Sertoli cells.
- Sertoli cells are known to secrete the hormone **Inhibin**, which plays a role in regulating the production of sperm by inhibiting the secretion of follicle-stimulating hormone (FSH).

### Step 4: Identify any other relevant cells in the testes.
- In addition to Sertoli cells, there are interstitial cells (also known as Leydig cells) located outside the seminiferous tubules. These cells produce and secrete androgens (such as testosterone), but they are not located inside the seminiferous tubules.

### Conclusion:
- Based on the information gathered, the correct answers are:
- **X**: Sertoli cells
- **Y**: Inhibin

### Final Answer:
The Sertoli cells of testes, which are present inside the seminiferous tubule of testes, synthesize and secrete Inhibin hormones.
