Question

Testosterone hormone is secreted by:

• A. Sertoli cells
• B. Epididymis
• C. Germ cells
• D. Leydig cells

Hint:

Leydig cells in the testes secrete testosterone, while Sertoli cells support and nourish developing sperm.

Answer 1

The Correct Option is D

Step 1: Understanding testosterone secretion.
Testosterone is the primary male sex hormone responsible for the development of male reproductive tissues, secondary sexual characters, and spermatogenesis. It is secreted in the testes.

Step 2: Analysis of options.
- (A) Sertoli cells: These provide nourishment to developing sperm, but they do not secrete testosterone.
- (B) Epididymis: This is where sperm is stored and matures, not where testosterone is secreted.
- (C) Germ cells: These are precursors of gametes, not hormone-secreting cells.
- (D) Leydig cells: Located in the interstitial tissue of testes, they are responsible for secreting testosterone.

Step 3: Conclusion.
The correct answer is (D) Leydig cells, as they secrete testosterone.
