How long can sperm live outside the body? Is there any way that a girl can get pregnant by getting a guy off? Can a girl get pregnant during her period? How long will sperm live inside a woman's body, and when would be the best time for a women to have sex? Does the clear substance that comes out before ejaculation contain sperm?
How long can sperm can probably live outside of the body? Probably about an hour. The rule of thumb most health educators use is to avoid contact with semen and other bodily fluids while they are wet. This is not only because there may be active sperm, but because there may be bacteria and virus that are still alive in the fluid. Just to be safe, it is best to use precautions around dried bodily fluids as well. This means not allow the fluid to come into direct contact with your skin.
Can you get pregnant when you do not have intercourse? Absolutely. It happens all the time with artificial insemination. But in those cases, doctors are using instruments to get the sperm to their final destination. It's less likely to occur if you accidentally sit on some wet semen or if your partner ejaculates outside of your vagina. But it is not impossible. All the little buggers needs is a warm wet environment, and who knows what they can accomplish. The fluid that comes out of the penis before ejaculation, is pre- ejaculate. It can contain sperm, and therefore it is possible to get pregnant even if the man withdraws before he ejaculates.
To be safe you should avoid getting sperm on your partner. Not just to avoid pregnancy, but also to prevent the spread of sexually transmitted diseases. Plus, it's a pain to clean up.
Now, sperm can live inside of a woman's body for two to five days, or up to a week if they reach the fallopian tubes. A woman's reproductive tract is hostile territory for sperm. The pH of the vagina kills off most of them, and of the one percent that make it past the mucus plug at the bottom of the cervix, most end up in the wrong tube. Given the vagina's apparent hostility towards the sperm, and the sperm's poor sense of direction – it seems like getting pregnant is a difficult thing to do. But the one million unplanned teen pregnancies and 1.5 million abortions that go on in the US every year suggest otherwise. A couple having unprotected sex for a year have an 85 to 90 percent chance of getting pregnant. After all, the egg, is about 85,000 times bigger than the sperm cell. It's not that hard to spot.
A woman usually releases one egg a month from her ovaries into the fallopian tube. The release of a mature egg occurs about 14 days before the start of her menstrual cycle. The first day of a woman's period is considered the first day of her cycle. The egg has to be fertilized within 24 to 48 hours of release. Fertilization takes place in the fallopian tubes. Of the 500 million sperm that are ejaculated, about 250 make it to this point, but the fallopian tubes are a much more scenic and inviting territory for the sperm. They can hang around for up to a week just waiting for that egg.
So – keeping in mind how long sperm live, and how long you have after ovulation – for an average woman with a 28 day cycle, getting pregnant is possible between the 8th and 20th days of the cycle with the 12th to the 16th days being the most fertile. Most women's periods are not a consistent 28 days and you can not really be sure. While the time during a woman's period is considered low risk for getting pregnant – it is not no risk. Add to that, the increased risk of getting a sexually transmitted disease during a woman's period. It's best just to use a safe and reliable method of birth control correctly, every time you have sex. Then you don't have to worry about doing all of this math or figuring out some kind of ejaculation voodoo that won't work.
