Located in the seminiferous tubules of the testes, Sertoli cells are specialized cells crucial for spermatogenesis. They provide structural support, nourishment, and an optimal environment for developing germ cells. Furthermore, Sertoli cells secrete factors regulating sperm development and establish the blood-testis barrier to protect germ cells from harmful substances.
