Sexual positions for baby-making

Find out how certain sex positions can increase or decrease your chances of conception.

Are some sexual positions better than others for conception?

Many experts suspect that the missionary position (man on top) affords the best opportunity for baby-making, though no definitive studies have been done on this question. This position allows for the deepest penetration and, as a result, places sperm closer to the cervix. For additional effectiveness, the woman can try elevating her hips with a pillow so her cervix is exposed to the maximum amount of semen.

Other possibilities (in case you get bored):

> Rear-entry, when the man enters the woman from behind, either lying down or kneeling, can also deposit sperm close to the cervix and aid conception.

> Lying side-by-side — this can be a relaxing position (great for promoting good sex) and easier on a partner who is overweight or has a bad back — can also help with conception.

Some clinicians also believe that a woman can further increase the likelihood of conception by remaining in bed for up to half an hour following intercourse, preferably on her back and, again, with a pillow under her pelvic region. In theory, this provides the sperm with additional travel time up to the fallopian tube along with help from the forces of gravity. For women predisposed to getting urinary tract infections and advised to go to the bathroom immediately after intercourse, this is obviously not the best option.

And finally there is the issue of orgasm. His is an absolute necessity for conception, and now new research shows hers may play a role, too. The contractions that accompany the female orgasm may help carry sperm further into the cervix.

What are the worst sexual positions for conception?
Experts recommend that you avoid having sex while sitting, standing, or with the female on top. These positions defy gravity and may discourage the upward mobility of sperm.

Are there any sexual positions that can help us conceive a boy or girl?
Not that science has confirmed, but legends abound. According to one, having sex with the woman on top will lead to a girl. Want to find out more? See our article on what the old wives say about choosing your baby's sex.
