When you 10-14 year if you have puberty
You need to be at least 18 years old, drug free, and have identification. You also need to be a male. Policies differ by sperm bank, but some common requirements involve age, health, and not being adopted.
No they can't because they need the x and y sperm that we need. They do not have that type of sperm.
Sperm is needed to reproduce.
no. sperm can live outside the male body for up to 72 hours
No, old men's sperm does not carry worms. Sperm cells only contain genetic material from the male donor and are not capable of carrying worms. If worms are present in the body, they are typically found in the intestines or other tissues, not in sperm cells.
Ejaculating a lot of sperm has no effect on your age.

#1, no, theyre too young to develop sperm. #2, why do you need to know?

Sperm cells need a tail to get food or energy while the egg isnt alive yet to need emergy......?
I'd say old. Male sperm swims faster but also dies faster, so there was a good chance it was waiting for the egg.
If the sperm is fresh yes. If the sperm is old no.
