If a man practice handjob regularly during his teenage, then his sperm count is reduced to such an extent that he may become sterile.
"Sterile" men have sperm with low motility rates (meaning there either isn't as many sperm as normal, or the sperm that is there is not as active as normal). This makes it much harder than normal for that male to fertilize an egg. How likely it is that he MIGHT still fertilize largely depends on what is causing the 'sterility'.
No. No person on Earth can become pregnant without sperm.
If it is a male rat then it become sterile.A castrated rat is a sterile rat.
A male transsexual is sterile. They cannot create viable testes yet.
epididymis
the sperm from the male if the organisim is sexual not asexual
Yes you can the offspring of such a union is called a Hinny and is not as desirable as a mule (which is the offspring of a stud donkey and a mare horse). Such unions are also sometimes difficult to comsomate, taking the horse a matter of years to get interested.
Yes, excessive alcohol consumption can harm male sperm by reducing sperm count, motility, and morphology. This can make it more difficult to conceive. It is recommended to limit alcohol intake to support healthy sperm production.
The testes hang outside in many mammals to keep them cool. Too much warmth is bad for them.
The tubular structure in which sperm mature and become motile is the epididymis. This process usually takes 20 days.
Sperm cells are produced in the male testes through a process called spermatogenesis. Spermatogenesis occurs in the seminiferous tubules of the testes, where spermatogonia (immature sperm cells) undergo several stages of development to eventually become mature sperm cells.
no she males do not have sperm because they are not in the male gender
