Question

What does ICSH stimulate?

• A. Leydig cells for testosterone production
• B. Spermatogenesis directly
• C. Oocyte maturation
• D. Growth hormone secretion

Hint:

In males, ICSH (or LH) stimulates Leydig cells for testosterone production, while FSH works on Sertoli cells for spermatogenesis.

Answer 1

The Correct Option is A

ICSH (Interstitial Cell Stimulating Hormone), also known as Luteinizing Hormone (LH) in males, is secreted by the anterior pituitary gland. It plays a crucial role in:
Stimulating Leydig cells in the testes to produce testosterone.
Testosterone supports spermatogenesis, development of male secondary sexual characteristics, and maintenance of libido.
Other options: - \( \text{Spermatogenesis directly} \): Testosterone indirectly supports it but does not directly cause it. - \( \text{Oocyte maturation} \): Related to LH in females, not males.
Final Answer: \[ \boxed{\text{Leydig cells for testosterone production}} \]
