'''Sertoli cells''' are a type of [[sustentacular cell|sustentacular]] "nurse" [[cell (biology)|cell]] found in human [[testes]] which contribute to the process of [[spermatogenesis]] (the production of [[sperm]]) as a structural component of the [[seminiferous tubule]]s. They are activated by [[follicle-stimulating hormone]] (FSH) secreted by the [[anterior pituitary|adenohypophysis]] and express [[FSH receptor]] on their membranes.
