0Introduction
Leydig cells are specialised endocrine cells found in the male reproductive system. They play an important role in male reproductive development and sperm production.
2. Location of Leydig Cells
Leydig cells are present in the interstitial spaces between the seminiferous tubules of the testes.
They are also known as interstitial cells.
3. Functions of Leydig Cells
1. Testosterone Secretion: Leydig cells secrete testosterone, the primary male reproductive hormone.
2. Spermatogenesis: Testosterone supports and maintains the process of sperm formation in the seminiferous tubules.
3. Development of Male Reproductive Organs: Testosterone helps in the growth and maintenance of male reproductive organs.
4. Secondary reproductive Characteristics: Testosterone is responsible for:
Growth of facial and body hair.
Deepening of the voice.
Increased muscle development.
Male-pattern body changes during puberty.
4. Hormonal Regulation
LH (Luteinising Hormone) is secreted by the anterior pituitary gland.
LH stimulates Leydig cells to produce and secrete testosterone.
5. Important NEET Points ⭐
Leydig cells are also called interstitial cells.
Location: Between seminiferous tubules.
Hormone secreted: Testosterone.
Stimulating hormone: LH.
Main function: Production of testosterone.
6. Quick Revision
LH → Leydig Cells → Testosterone → Male Reproductive Development
