Sperm is needed to reproduce.
no. sperm can live outside the male body for up to 72 hours
Sperm cells need to be kept cooler than body temperature to maintain their health and viability. Heat can damage sperm cells, so it is important for them to be stored and maintained at a slightly lower temperature than the body.
eggs to fertilise and sperm to fertilise it
yes
As new sperm are made in the body, there is no shortage of them in the body.
Yes, it is true that sperm can develop normally only in sightly cooler temperature than normal body temperature. Sperm need a cooler temp than the rest of the body. The scrotum keeps sperm lower than the body, but tight shorts can keep the testicles too warm for the sperm.
The scrotum of a male, is outside the body, because sperm production requires a cooler environment then the internal body. So, the external location actually is required for production of the sperm.
Production of sperm is reduced. The testicles need to be cooler than core body temperature for the production of numerous and viable sperm.
No, for fertilization to occur, the sperm needs to be deposited into the female reproductive system, specifically the fallopian tubes where it can meet an egg. If the sperm is already in the body, it would need to travel through the cervix, uterus, and into the fallopian tubes to reach the egg.
how long can sperm live in a women's body
because the body is too warm for the sperm if they were in the body they would die, the only mammal that has its sperm in the body are dolphins and whale, where not sure how they keep it in their body without them dieing
The female body does not release or have "sperm" - women have "eggs" that the mans sperm fertilizes to achieve conception.
