What is the Meaning of Sertoli Cell Function?

The critical physiological role played by the somatic Sertoli cells within the seminiferous tubules of the testes, which serve as nurse cells to support and regulate all stages of spermatogenesis, the production of sperm. These cells form the blood-testis barrier and secrete essential factors, including androgen-binding protein and inhibin, which modulate the local hormonal environment and systemic feedback loops. Optimal function is non-negotiable for male fertility.

What is the Origin of Sertoli Cell Function?

The term is named after the Italian physiologist Enrico Sertoli, who first described the cells in 1865, combining his name with the biological term function. Its clinical relevance is centered on male reproductive endocrinology and the assessment of testicular health. The Sertoli cell is considered the fundamental structural and regulatory unit of spermatogenesis.

What is the Mechanism of Sertoli Cell Function?

Sertoli cells are the primary targets for Follicle-Stimulating Hormone (FSH), which stimulates them to produce factors necessary for germ cell maturation. They also tightly control the local concentration of testosterone, which is essential for spermatogenesis, by secreting androgen-binding protein. Inhibin, another key secretion, provides negative feedback to the pituitary gland, helping to regulate FSH release and maintain hormonal balance within the HPG axis.
