What medical science says: The foundational studies on sex by Masters and Johnson4 found no evidence of what they call “sperm insuck”; however, the researchers didn’t study actual intercourse. One more recent study showed some evidence that sperm retention does occur when a woman orgasms. But the researchers were cautious about the results, noting that a larger sample size is needed to make a better conclusion5.
So can orgasms help to get pregnant? The science isn’t clear yet, but maybe. What is clear is that if both partners enjoy sex, they are more likely to engage in more sex. Thus, they are also more likely to get pregnant.
There is no proof that sex positions to get pregnant can help in conception. Even then, there may be some benefits for some positions over others, namely those that promote deep penetration.
Sex and conception are complex, and many other factors come into play, such as fertility, frequency of sex, and orgasm. It’s not just about sex positions to get pregnant. Forming a close bond and enjoying sex together can be just as or even more important.
