Role of Sertoli Cells in Spermatogenesis
Sertoli cells, also known as nurse cells, play a crucial role in the development and nourishment of male germ cells within the seminiferous tubules of the testes. Here’s how they function:
Nutrition Supply
- Sertoli cells provide essential nutrients to the developing sperm cells (spermatogonia, spermatocytes, spermatids, and spermatozoa).
- They create a supportive environment by secreting factors that promote germ cell proliferation and differentiation.
Structural Support
- These cells form the blood-testis barrier, which protects germ cells from harmful substances in the blood and ensures a stable environment for their development.
- They also help maintain the unique microenvironment required for spermatogenesis.
Hormonal Regulation
- Sertoli cells respond to follicle-stimulating hormone (FSH) and testosterone, regulating the process of spermatogenesis.
- They secrete inhibin, a hormone that provides feedback to the pituitary gland to regulate FSH levels.
Phagocytic Activity
- Sertoli cells can engulf and digest residual cytoplasm from spermatids during maturation, ensuring efficient development of sperm.
Conclusion
In summary, Sertoli cells are vital for providing nutrition, structural support, hormonal regulation, and maintenance of a conducive environment for the maturation of male germ cells. This makes option 'B' the correct answer for which cells provide nutrition to the male germ cells in the seminiferous tubules.

The correct answer is B: Sertoli cells.
- Sertoli cells:
- Located in the seminiferous tubules of the testes.
- Provide support and nutrition to developing male germ cells (spermatogonia) through various stages of spermatogenesis.
- Create a blood-testis barrier, protecting germ cells from harmful substances.
- Secrete growth factors and hormones essential for germ cell development and maturation.
