• A. anterior pituitary
• B. posterior pituitary
• C. testis
• D. hypothalamus

Answer 1

The correct option is A

anterior pituitary

The correct option is A.

Explanation of correct option:

1. Leydig cells are responsible for the production of testosterone in males.
2. The anterior pituitary controls these cells.
3. It secretes a hormone known as the Luteinising hormone (LH).
4. LH acts on the Leydig cells to produce testosterone in males.

Explanation of incorrect option:

Option B:

The posterior pituitary is responsible for producing vasopressin, oxytocin, and melanin stimulating hormones.

Option C:

The testis does not release any hormone which stimulates the Leydig cells.

Option D:

The hypothalamus is responsible for secreting gonadotropin-releasing hormone (GnRH) which causes the pituitary to secrete LH.

Final answer: Leydig cells are stimulated by the hormone produced from the anterior pituitary.
