Contraception success rates are measured in typical use versus perfect use. Typical use refers to how people realistically use the method, while perfect use refers to, well, perfect use. Perfect use also involves taking precautions before having sex again. To make sure the penis is totally free and clear of any residual seem, the person needs to urinate and clean off the tip of their penis before going in for another round. This can be a bit of a mood killer for some.
How effective is the pull out method? To most people, that sounds pretty great. However, the pull out method has some significant downsides. This means roughly 27 out of every women using this method for a year will become unintentionally pregnant. Perfection, though, is not what happens in real life.
Credit: Jamie Chung Advertisement It starts with an age-old question: If a man pulls out before ejaculating, can a woman still get pregnant? In bedrooms, basements and the backs of cars worldwide, millions of sexually active humans make choices or regret them based on what should be foundational fertility knowledge. Dig deeper, though, and it quickly becomes unclear exactly where the risk is coming from. Its job is to create a hospitable ride for sperm that ultimately pass through the urethra during ejaculation.
Sorry, we can't resist puns. Out of couples who were withdrawal rock stars—meaning they pulled out correctly every time they had sex—about four of them would get pregnant in a year. First off, we have very limited scientific information about pre-cum so there can be confusion about it even among experts. Three small studies from years ago found no sperm in pre-cum, but there were only 43 guys in all of these studies combined. Some of the men in the studies had health problems, and it appears that the pre-cum samples they provided were not analyzed immediately so it may have been it difficult to tell if their sperm were swimming normally.
