Sertoli cells are regulated by the pituitary hormone known as

Sertoli cells are the cells that line the seminiferous tubules in the testis. These cells protect the spenatids and convey nutrients to both the developing and mature spermatozoa. Sertoli cells are regulated by FSH (Follicle Stimulating Hormone). As the FSH receptors are confined to the Sertolic cells.
FSH stimulates Sertoli cells to produce androgen-binding protein and inhibin and together with testosterone, promotes the proligeration of Setolic cells
