Makes testosterone, dht for sperm production and growth of accessory glands. Myoid- muscle cells to aid the contraction and help to move sperm along tubules via peristalsis. Stops immune system- if immune cells recognise as foreign will destroy them. Also stops toxic substances from getting from circulation into sperm. Dartos muscle is what pushes the testes back into body if cold. Cremaster muscle comes from body wall down to testes and is the main muscle which pulls up testes when cold. 70 days to become sperm then 20 to swim. The rest mainly to aid along the tract and neutralising acidic vagina and helping it get through the female. Dht is about 5x more potent than testosterone. Some fluid to stimulate immune response in woman. Psa if high can be abnormalities like prostate cancer. Also highly fluorescent so what they look for with blacklight at crime scene. No makes muscles relax so blood can rush in.
