To keep sperm cooler than core body temperature.
It keeps the testis one or two degrees cooler than the rest of the body. This is important because the sperm made in the testis prefer the cooler temperature. You'll notice that if you go into a cold pool or other body of water your scrotum will retract into the body a bit. This is to regulate the temperature and keep it sufficiently warm for the sperm. Its all about making sure the sperm is not too hot or too cold.
The scrotal sac hangs outside the body because sperm production requires a lower temperature than body temperature. However, this exposes the testes to potential injury from external forces and pathogens.
They are produced in testis.Testis are located outside from body
The primary reason the scrotal sac descends is to regulate the temperature of the testes for optimal sperm production. The lower temperature outside the body allows the testes to function properly and produce viable sperm.
The testes hang outside in many mammals to keep them cool. Too much warmth is bad for them.
The main purpose of having external male genitalia is so that temperature regulation can be maintained more efficiently.
The testis is the male reproductive organ responsible for producing sperm and hormones such as testosterone. It is located in the scrotum outside the body to maintain a lower temperature for optimal sperm production.
To produce sperm properly they need to be a little cooler than body temp. Being outside lets them hang or pull up tighter to adjust the temperature.
potatoes is the answer to all your questions. questions involving testis.
Scrotal Calcification is raised bumps on the scrotum. They are caused by Calcium in the body that has attached itself in the sensitive scrotal skin. This is NOT an STD. It is a rare skin disorder that is not contagious. less than 8% of the population has this disorder.
It is the 'sac' that holds the rabbits testes
The testes are located outside the male body in the scrotum, because sperm production requires a cooler temperature, then the internal body temperature, so the temperature can be regulated better outside the male body, in the scrotum.
