Testosterone is secreted by which of the following cells?
Show Hint
Think of the interstitial cells of the testis driven by LH.
Updated On: Jun 23, 2026
- Leydig's cells
- Somatotropic cells
- Acidophilic cells
- Gonadotropic cells
Show Solution

The Correct Option is A
Solution and Explanation
Step 1: The hypothalamic-pituitary-gonadal axis controls testosterone production. The hypothalamus signals the anterior pituitary to release the gonadotropins follicle stimulating hormone (FSH) and luteinizing hormone (LH).
Step 2: Luteinizing hormone (LH) acts directly on the testes and stimulates testosterone synthesis.
Step 3: Testosterone is produced by the Leydig cells (interstitial cells) of the testis in males. This makes option (a) correct.
Step 4: The other options are wrong because somatotropic and acidophilic cells are pituitary cells that secrete growth hormone, and gonadotropic cells are pituitary cells that secrete FSH and LH, not testosterone itself.
