Sertoli cells are essential somatic cells within the seminiferous tubules that provide structural and metabolic support for developing germ cells. Often referred to as “nurse cells,” they regulate the microenvironment necessary for spermatogenesis by facilitating nutrient exchange, phagocytosis of residual cytoplasm, and secretion of regulatory factors.
In andrological research, Sertoli cell function is closely linked to fertility potential. Dysfunction may disrupt the blood–testis barrier, impair germ cell maturation, and alter hormonal signaling. Clinical evaluation of male infertility increasingly considers the integrity of Sertoli cell activity, particularly in cases where conventional semen parameters appear inconclusive.
Understanding the cellular mechanisms governing spermatogenesis enhances diagnostic accuracy and guides targeted erotic therapeutic strategies.
