There are certain positions that are said to be more conducive to helping a couple conceive. Many experts feel that the missionary position (man on top) is the best position for those trying to conceive. Because this position allows for deeper penetration by the male, the theory is that the sperm will be closer to the cervix and stand a greater chance of reaching it in a timely manner.

For additional help the woman can try elevating her hips with her hands or a pillow to allow her cervix to experience exposure to the maximum amount of semen. (The theory here being that in this position less semen will drip out prematurely.)

But for those who don't like the missionary position or get bored with it, there are other positions that can foster good baby-making environments. These generally include the rear-entry positions, lying side-by-side, and other postures that encourage deep penetration. Some clinicians also state that the woman lying in bed (again on her back with her hips elevated by a pillow) for up to a half-hour after sex can increase the chances of successful conception. A woman's OB/GYN may be able to offer some helpful advice with regard to this topic.

In addition the positions that are considered the worst for conception are any of the woman-on-top positions and any standing or sitting positions, as these positions have gravity working against the flow of sperm.

Taking it a step further, some people believe that certain positions are also more conducive to allowing a couple to conceive a baby of specific gender, but there is no scientific proof that a certain position determines the baby's gender. Some old wives' tales on this subject include using the rear-entry or standing positions to guarantee a boy and using the missionary and woman on top to ensure a girl. Of course, these are only superstitions, but if you want to give these myths a try, feel free — there's no harm in trying, and practicing can be wonderful.
