Question

Synthesis of testosterone by Leydig cells is regulated by

• A. FSH
• B. TSH
• C. LTH
• D. ICSH

Answer 1

The correct option is D ICSH

Luteinizing hormone (LH) in males is called ICSH (Interstitial cell stimulating hormone). It is secreted from anterior pituitary and stimulates the Leydig cells of testes to produce testosterone. It is male sex hormone that stimulates the development of secondary sex organs and sexual characters. It also stimulates spermatogenesis i.e. production of sperms from the germ cells.

So, the correct answer is 'ICSH'.
