Verified by Toppr

The correct option is A Interstitial cells of the testis
Leydig cells are also known as interstitial cells of the testis. They are found adjacent to the seminiferous tubules in the testicle.
The Interstitial cells of the testis produce testosterone(male sex hormone) in the presence of the luteinizing hormone (LH).
In male humans, testosterone plays a key role in the development of male reproductive tissues such as testes and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair.
Hence the source of male sex hormones is Interstitial cells of the testis.
So, the correct answer is 'Interstitial cells of the testis'.
