Question

What is the role of Leydig cells in reproduction?

Answer 1

Leydig cells:

1. Leydig cells are interstitial cells located adjacent to the seminiferous tubules in the testes.
2. Leydig cells are present in the interstitial spaces in the testicular lobules.
3. They secrete androgens, primarily testosterone.
4. Androgens stimulate the process of spermatogenesis, i.e. the formation of sperms, which is one of the main steps in reproduction.
5. Androgens also regulate the development of accessory sex organs, and secondary sexual characteristics and influence libido.
6. Leydig cells perform the function of sperm production or spermatogenesis, controlling sexual development, and maintaining secondary sexual characteristics and behaviors.
