sperm

Jack, Thanks for sending in your question! Although you've asked about the lifespan of sperm outside your body (and anyone else's), I would like to spend a little time addressing your fear of touching your sperm, too. That's a really important concern, because I want you to be able to be happy and...

Without some help...no. In order for a pregnancy to occur, the first thing you need is a sperm and an egg. Individuals who have ovaries are going to be able to provide the ovum (or egg) while individuals who have testes are going to provide the sperm. So if you have two individuals who have ovaries...

The most likely possibility is that what you're seeing coming out of your vagina is simply semen: the sexual fluid which carries sperm. The vagina isn't a bottomless pit: it ends with the cervix, the base of the uterus. The opening to the cervix -- called the os -- is incredibly small. It can dilate...

Understand that if a person with a penis is aroused and/or erect, then there is likely some pre-ejaculate at some point. If his penis is visible, you will likely be able to see it, but for obvious reasons, if it's inside your vagina or your mouth, you're not going to be able to see it, and both you...

Pre-ejaculate can contain sperm, and it's something that (especially during penetrative activities) usually goes unnoticed by both partners. The vagina is a wet environment, so you are not going to be able to feel the addition of some extra fluid. And (no matter what a partner may claim) men...

Your boyfriend needs to understand and accept that it's very unlikely he never pre-ejaculates if he does fully ejaculate, too. In other words, if, at his age, he's reached the stage of puberty where he can ejaculate, then he also does pre-ejaculate. Pre-ejaculate is how the penis "prepares" itself...

Sperm are hearty, but they're not that hearty! As long as your hands were dry when you had contact with your girlfriend, you've got nothing to worry about from this situation. Dry ejaculate or pre-ejaculate poses no risk. I'm not quite sure what you mean by saying you "poked" your girlfriend, but I...

For of all you need to understand that the length of time you have sex has nothing to do with your risk of pregnancy. It doesn't matter if it was 15 seconds or 15 minutes; it doesn't matter. If your partner did not ejaculate, your risk of pregnancy is pretty low. Your risk of sexually transmitted...

In truth, it takes a more than one sperm to fertilize an egg. Only the one does the fertilizing, but that one sperm needs a couple hundred "helper" sperm to do the job. That isn't to say pre-ejaculate cannot cause pregnancy. From all we know practically and scientifically, on some occasions when pre...
