it allows the sperm to swim
They can move about 'swim' and find an egg to fertilize.
it usually swims in groups but sometimes individual sperms tend to go ahead of the other sperms which makes them the leading sperm. sperms also have swimming lessons every weekend
12yo can get each other pregnant so there's no particularly advanced performance required. All you have to do is ejaculate inside her vaginal canal, you don't need to be deep or anything. Sperms swim.
It's true a single sperm only has to travel a few inches, but sperm are only a thousandth of an inch themselves, so it's a long journey on their scale.
Sperms have tail and they swim. Terrestrial condition does not permit that. So, it is best to have internal fertilization where sperms can creep up the lining of the female reproductive tract, rich in mucus, and find the ovum to fertilize.
This is kinda gross. I suppose they have a flagella so they can "swim" up the vagina to find the egg. No other cell needs to "swim." The flagella acts as a tail.
You can ejaculate just at the entrance and don't have to go inside. Sperms swim.
Oh yes you can get pregnant if he ejaculates or have pre-ejaculation right at the vaginal entrance. Sperms swim.
no,they do not need a swim bladder as they do not swim...
well that's easy get bored eat them from going fishing or stores watchem swim feed the 1 a week or 1 every 2 weeks
You only need your arms and legs, and a body of water to swim in.
