“Is it possible to “flush out” sperm after you have sex to help prevent pregnancy?”
It may seem like using the bathroom or washing down there after sex may “flush out” sperm and reduce your chance of pregnancy, but that’s not the case.
Your urethra and vagina are two different holes. Peeing after sex won’t rinse sperm out of the vagina, because you don’t pee out of your vagina.
When someone ejaculates, they release millions and millions of sperm, and it only takes one to cause a pregnancy. If there’s already an egg in the fallopian tubes, sperm may fertilize it. If not, sperm hang out for up to six days waiting for an egg. There’s really nothing you can do to get every sperm out of your vagina and other reproductive organs once ejaculate is in there. Washing, peeing, douching or using spermicide after unprotected sex won’t help prevent pregnancy.
The only thing that can prevent pregnancy after unprotected sex is emergency contraception. You can take EC up to five days after unprotected sex. If you’re having vaginal sex you should use a birth control method to help prevent pregnancy along with condoms to help prevent STIs.
