Organs and structures of the male and female reproductive systems.
Sertoli cells play a vital role in the human reproductive system by providing essential support and protection to developing sperm cells within the seminiferous tubules.12
Their primary functions include:
- Nutritional Support: They nourish immature germ cells by supplying them with necessary nutrients and blood products.1
- Mechanical Support and Protection: Sertoli cells provide a structural framework that mechanically supports and protects developing spermatogonia and spermatocytes.12
- Transportation: As germ cells mature, Sertoli cells assist in transporting them from the outer wall of the seminiferous tubule toward the central lumen (the central channel of the tubule).1
- Hormonal Regulation: These cells produce inhibin, a hormone that helps regulate the process of spermatogenesis by inhibiting the secretion of follicle-stimulating hormone.2
During development, primary sperm cells attach themselves to the Sertoli cells, which facilitate their maturation process as they move toward the center of the tubule to eventually become spermatozoa.12
