In the male productive system, testis (pl. testes) produces the hormone that develops the secondary sexual characteristics.
You have interstitial cells in between seminiferous tubules in testis. These cells are called Leydig cells named after the German anatomist Franz Leydig, who discovered them in 1850. (You can remember the name of this scientist easily. As it is somewhat like 'Ladies cells'.)
