Testis Structure & Leydig Cell Function — NEET Biology
✅ Asked in NEET 2022Identify the cells that produce androgens in the testis. (NEET 2022)
Identify the cells that produce androgens in the testis. (NEET 2022)
Answer & NCERT explanation
Correct answer: B — Leydig cells
Leydig cells (interstitial cells) in the testis produce androgens, primarily testosterone. These cells are located in the interstitial tissue between seminiferous tubules and respond to LH hormone. Sertoli cells support sperm development and secrete inhibin, spermatogonia are germ cells that develop into sperm, and follicular cells are found in ovaries, not testes.

A pair of testis is present in the scrotal sac (outside abdomen) of male individuals. Testis performs dual functions as a primary sex organ as well as an endocrine gland. Testis is composed of seminiferous tubules and stromal or interstitial tissue. The Leydig cells or interstitial cells, which are present in the intertubular spaces produce a group of hormones called androgens mainly testosterone.
The testis has two key components: seminiferous tubules (produce sperm) and interstitial/stromal tissue containing Leydig cells (produce hormones). NTA specifically tests that Leydig cells produce androgens, especially testosterone, not just any cells in the testis. Students often confuse which cell type produces hormones versus sperm, or forget that Leydig cells are located in intertubular spaces. Remember: Leydig cells = hormone production (endocrine function), Seminiferous tubules = sperm production (exocrine function). This dual function of testis as both reproductive organ and endocrine gland is fundamental to understanding male reproduction and hormonal control.
