Best sex position to get pregnant
The few studies that looked at coital connections hint that missionary position might offer a slim anatomical advantage. The theory: In guy-on-top, a woman's cervix can dip more easily into the vaginal semen pool, giving sperm access to the protective cervical mucus. "There's no scientific data on that, though," says Kelly Pagidas, M.D., a fertility specialist with Women & Infants Center for Reproduction and Infertility in Providence and an associate professor at Brown Alpert Medical School.
Plus, not all women are built the same way. "Having women on their backs makes sense for women who have an anteverted uterus, one that is tilted forward, which is about two-thirds of the population," Dr. Kingsberg notes. "But a third of women have a retroverted uterus, one that's tilted backward, so missionary wouldn't offer any advantage for them."
Some men simply don?t like missionary style, since it can be tiring for them. "The missionary position is more demanding for men because they have to use their muscles to keep from putting their full weight on you, putting extra pressure on them," says Mindy R. Schiffman, Ph.D., a clinical psychologist and sex therapist at New York University's Fertility Center and in private practice in New York City. In this case, couples can try a different position, such as doggy style.
This popular position puts the woman on all fours with the man entering from behind. It allows for deeper penetration, which gives semen increased access to the opening of the cervix.
In this position, the woman places herself on top facing away from her partner?s face. The angle allows her to control the depth of the penetration for optimal effectiveness.
When engaging in this position, the couple faces each other during intercourse while laying on their sides. Not only is it romantic (which may ease the nerves involved with baby-making sex), but it also allows for deep entry.
Like doggy style, this position involves the man entering from behind. The difference, though, is that the woman lies on her stomach and he lowers himself over her. Rear entry is a surefire way to get deep penetration.
Who says baby-making sex can?t be a little adventurous? In this athletic position, the woman holds herself up with her hands while her standing partner grabs her legs, pulls them around his thighs, and enters her. Again, it allows for deep penetration and closeness to the cervix.
Your Favorite Position
It's more likely that the very best position is, in fact, your favorite one. It doesn't matter if you're twisted like a Bavarian pretzel or lying still as a statue, as long as your partner gets the job done. And if it provides a toe-curling climax, all the better!
"There was some research that a woman's orgasm did help move semen into the uterus terms of the contractions," Dr. Kingsberg says. But she cautions against stressing if you don't regularly climax. "Honestly, there's so little science behind it that we don't want to put pressure on women to have to reach orgasm."
What's most important is to keep up a consistent routine, and not necessarily an obsessive one. "In studies about frequency of sex, there wasn't a statistical difference between rates of pregnancy for people who have intercourse every other day leading up to ovulation and those who do it every day," says Jani Jensen, M.D., a reproductive endocrinologist and assistant professor at the Mayo Clinic in Rochester, Minnesota. "Besides, trying to have it daily can be a huge chore."
With hundreds of millions of sperm released in each male orgasm, any unprotected sex around the time of ovulation could result in a pregnancy. As long as sperm enter the vagina, you have a chance to conceive.
No certain positions during sex have been proven to increase likelihood of conception. Yet certain positions may be better than others for ensuring those little swimmers find their way up to the egg. The missionary (man on top) and doggie-style positions (man behind) allow for deeper penetration ? bringing sperm in closer proximity to the cervix.
In the standing and woman-on-top positions, gravity works against you. Yet standing up right after sex shouldn?t reduce your odds of a pregnancy. Sperm are pretty good swimmers. Once deposited in the vagina, they can reach the cervix within 15 minutes.
Though you don?t need to raise your legs in the air after sex, or even lie flat on your back to help them get there, it can?t hurt. Placing a pillow under your lower back will also keep the sperm swimming in the right direction.
