Are some sex positions better than others?
You may have heard that some positions, such as your partner on top (missionary position), are better than others for conception. In fact, there’s no evidence to back these theories up. Experts just haven’t done the research yet.
What experts have done, though, is use scanning to reveal what’s going on inside when you’re doing the deed. Some brave couples volunteered to be scanned using magnetic resonance imaging (MRI) while having sex.
The research looked at two positions: the missionary position and doggy style. (Doggy style being when you’re on all fours, and your partner enters you from behind).
Common sense tells us that these positions allow deep penetration and are likely to place sperm right next to your cervix (the opening of your uterus).
The MRI scans confirm that the tip of the penis reaches the recesses between the cervix and walls of the vagina in both these sexual positions. The missionary position ensures the penis reaches the recess at the front of the cervix. The rear entry position reaches the recess at back of the cervix.
