Document Summary

Castrati often lived to be famous. Testis: site of hormone and sperm production, most important reproductive structure in a male, located inside the scrotum, found externally, must have a temperature that is product. 2 degrees c below normal body temperature (hence their location outside of the body: cell degradation occurs in sperm/in the testis so that they don"t explode, seminiferous tubules. Where the sperm is made join up with the epididymis (stores sperm and mature that sperm can"t swim until it is matured) Has cells responsible for producing sex hormones. Sufficient testosterone enable spermatogenesis (and other body changes) to occur spermatocytes (moves up and locked between 2 sertoli cells the more mature the cell gets the closer to the lumen it gets. Primary spermatocytes divide into 2 secondary spermatocytes which are all. Genetically unique (produced through meiosis meiosis 1 and 2) Secondary spermatocytes divide again through meiosis to produce 4 spermatids.
