How Can You Prevent Pregnancy After Sperm Enters the Body?
The only scientifically proven way to prevent pregnancy after sperm has entered the vagina is through emergency contraception (EC). Often called the "morning-after pill," EC pills can be taken up to 120 hours (5 days) after unprotected sex. Nemours KidsHealth and Lovima both confirm this. These pills are not 100% effective, but they significantly reduce the chance of pregnancy. PMC states that ECPs reduce the chance of pregnancy by about 75%. It's crucial to remember that once sperm has passed through the cervix, there's no method to physically remove it. Medical News Today clarifies this point.
Emergency contraception works in several ways, primarily by delaying or preventing ovulation (the release of an egg) or by interfering with fertilization or implantation. Several types of EC exist, including pills containing levonorgestrel or ulipristal acetate, and copper intrauterine devices (IUDs). The effectiveness of EC varies depending on the type and how soon it's taken after unprotected sex. It's vital to consult a healthcare professional for advice on the best option for your individual circumstances. The timing is crucial; the sooner you take EC, the more effective it is. This is emphasized across multiple sources.
Other Methods & Considerations
While EC is the only method to prevent pregnancy after sperm entry, other methods prevent pregnancy before sperm enters the body. These include barrier methods like condoms, which physically prevent sperm from reaching the cervix, as noted by Cleveland Clinic and NIH. The withdrawal method (pull-out method), while sometimes attempted, is unreliable because pre-ejaculate may contain sperm. Cleveland Clinic highlights this. Hormonal methods like birth control pills also prevent pregnancy by preventing ovulation. Queensland Health describes the various types of contraceptive methods. These preventative measures are far more reliable than trying to prevent pregnancy after sperm has already entered.
