Interstitial cells, also known as Leydig cells, play a crucial role in the male reproductive system. Their primary function is to produce testosterone.
Testosterone is an essential hormone for the development of male sexual characteristics, including muscle mass, bone density, and libido. These cells are located in the testes, specifically in the interstitial tissue between the seminiferous tubules where sperm production occurs.
While interstitial cells are involved in the overall functionality of the male reproductive system, it is important to note that they do not produce sperm, inhibin, or nutrients. Instead, they promote spermatogenesis indirectly by providing the necessary hormonal environment, directly influencing the Sertoli cells that support sperm development.
