Document Summary
Where testosterone and sperm are produced hundreds in one testis. Where sperm travels from the seminiferous tubules for storage and maturation before release from the body note: males can store over a month"s supply of of sperm. Seminiferous tubules recall where testosterone and sperm are produced tube wall made up of multiple cell types, inside of the tube is called the lumen. Leydig cells produce testosterone located outside of seminiferous tubule, near blood vessels. Sertoli cells ( nurse cells") support and regulate spermatogenesis: through production of various substances. Spermatocytes developing sperm cells found between sertoli cells in tubule wall note: basement membrane on outermost edge of tubule wall describe spermatogenesis with all of the stages of cell division, beginning with the. Spermatogonia process of spermatogenesis is initiated at puberty: sufficient testosterone is produced to enable spermatogenesis (and other body changes) to occur. Spermatogonia: like stem cells, replicate and divide to produce more.
