Where are the Leydig cells present? What is their role in reproduction?

Testes:

1. A pair of testes, as well as accessory ducts, glands, and the external genitalia, make up the male reproductive organ.
2. Seminiferous tubules are coiled masses of tubes found within the testes.
3. Through a process known as spermatogenesis, these tubules are responsible for creating sperm cells.

Leydig cells:

1. They are also called the interstitial cell.
2. Leydig cells are found outside the seminiferous tubules in the interstitial spaces.

Role in reproduction:

1. Leydig cells secrete male sex hormone androgen.
2. The principal androgen is testosterone.
3. Testosterone stimulates spermatogenesis.
4. Testosterone is responsible for the development of male secondary sex organs (such as epididymis) and male secondary characteristic (such as beard and mustache)
