Sex positions for baby-making
Are some sexual positions better than others for conceiving?
There's no evidence that any particular sexual position is more likely to lead to conception. You may have heard that some positions, such as the missionary position (man on top), are more promising than others because sperm is deposited closest to the cervix, but there aren't any scientific studies to back this up.
Proper timing, on the other hand, is a crucial factor. Most women are fertile for only six days at most during each cycle, the so-called fertility window. The fertility window opens five days before ovulation and closes on the day of ovulation. You're most fertile just before ovulation, so to make conception more likely, have sex during the days just before you expect to ovulate and then again on the day of ovulation.
There's also no truth to the notion that you shouldn't have sex more often than every other day if you're trying to conceive. If your partner's sperm is normal, it will replenish from day to day, so there's no need to wait. The main thing is to have sex close to the day you ovulate.
Does having an orgasm boost my chances of conceiving?
Some people believe that a woman who climaxes after her partner ejaculates is more likely to get pregnant, but there's no evidence to support this notion.
The female orgasm isn't necessary for conception, but it is possible that the uterine contractions from an orgasm propel sperm toward the fallopian tubes. (The uterus also contracts involuntarily when you're not having sex, especially around the time of ovulation.)
Should I stay lying down after having sex to help my chances of conceiving?
There's no evidence that this makes a difference either. As ovulation approaches, you may notice sticky vaginal discharge (cervical mucus). This type of mucus 'captures' sperm, so even if some semen seeps out, most of the sperm stay alive in your body. And with millions of sperm in every ejaculation, there should be plenty of them making their way toward the egg, even if you get up right away.
