They are just babies then. The spermatocyte splits into two spermatids. The male sex cell is what determines if a baby is a boy or a girl. They look sometimes like tadpoles when you see them under a microscope. When they grow up to be adults they are called spermatozoa and have a head and a body and a tail. The sperm go from the seminiferous tubules through some ducts that end up in a tube called the epididymis. It is against the back wall of the testicle and stores sperm. This is where they go to school and grow up. They are thrown in the “water” and told sink or swim. They are there for about two to four weeks. When they enter the epididymis they are blanks but when they leave they are fully loaded. If there is no road block they will follow a winding path to the abdominal cavity (some of them do get lost because they do not stop to ask for directions).
