Document Summary
Fsh cells act on sertoli cells which trigger spermatogenesis inhibin plus testosteron works in feedback mechanisms the main gonadotropin that acts there is either one layer of spermatagonia or stem cell of germ cells lining the basement membrane. Fsh works on sertoli cells that form abp which bind testosterone made by interstitlial cells which activates spermatogonia stem cells for mitotic division. Sertoli cells and spermatogenesis this diagram gives an idea on the complex process. When you look at the image the cells are packed. Genetic basis of spermatogenesis its multigenic which is one process that requires multiple genes to function which is found on the y chromosome. Sry is the determining gene for male development. Dna and rna of the sperm has to be condenced and compact so that there is a. Cellular basis of spermatogenesis small head for the sperm summary of the molecular controls of spermatogenesis.
