Sertoli cells

Sertoli cells are specialized cells located in the testes that support and nourish developing sperm cells. They form the “nurse” environment within the testes, providing structural support and regulating the process of sperm production through the release of hormones and nutrients. Sertoli cells also form a barrier called the blood-testis barrier, protecting developing sperm from potential toxins and immune attacks. Additionally, they help control the levels of certain hormones, ensuring proper development of sperm cells. Overall, Sertoli cells are essential for healthy male fertility, shaping the environment needed for sperm to mature properly.
