Would going to the bathroom 20 minutes after intercourse decrease chance of getting pregnant?

Going to the bathroom 20 minutes after intercourse does not decrease the chances of getting pregnant. Urine retention has no effect on preventing sperm from reaching the egg.

Pregnancy occurs when a sperm fertilizes an egg. For fertilization to occur, sperm must be present in the female reproductive tract at the time of ovulation, which is the release of an egg from the ovary. After ejaculation, sperm can travel through the vagina, uterus, and fallopian tubes to reach the egg. The likelihood of pregnancy depends on several factors, including the timing of intercourse in relation to ovulation, the number and quality of sperm, and the woman's overall fertility.

Going to the bathroom after intercourse does not remove all the sperm from the reproductive tract. Even if some sperm are flushed out with urine, there may still be enough remaining to fertilize an egg if conditions are favorable. Urination does not affect the upward migration of sperm towards the uterus and fallopian tubes.

If you are concerned about preventing pregnancy, it is important to use reliable methods of contraception, such as condoms, oral contraceptives, or intrauterine devices (IUDs). These methods are effective in preventing unwanted pregnancies when used correctly and consistently.
