Which provides nutrition to maturing sperms?

Sertoli cells provides nutrition to maturing sperms. Sertoli cells occur in human testes. Each lobule of testes contains one to three seminiferous tubules in which the sperms are produced. Each seminiferous tubule is lined on its inside by two types of cells called male germ cells (spermatogonia) and sertoli cells. Sertoli cells are also known as nurse cells. They provide nutrition to spermatozoa. Spermatozoa are developing sperms. Heads of spermatozoa are embedded in the sertoli cells. Sertoli cells also secrete called inhibin which suppresses FSH synthesis.
