The most important thing a couple or individual can do to increase chances of natural pregnancy is to monitor ovulation (the release of a mature egg for fertilization), and time intercourse to that (see below). After doing everything they can in that regard, men and women should primarily focus on the health of their reproductive systems (more below).
Many myths and misconceptions surround conception, particularly how to have sex in order to get pregnant. There is no evidence that the likelihood of pregnancy is increased by certain sexual positions, prolonged rest by the woman after intercourse or by the woman lying in a certain position after sex. Normally, sperm ejacul*ted into the vagin* reach the fallopian tubes where egg fertilization occurs within minutes, no matter what position is taken during intercourse.
However, many commonly used vagin*l lubricants can negatively affect sperm survival and motility (sufficient movement to get to the egg). When trying to get pregnant, avoid using most commercial lubricants, saliva or olive oil during intercourse.
ASRM recommends canola oil, mineral oil, or hydroxyethylcellulose-based lubricants (Astroglide Natural, Kama Sutra Premium), as necessary.
How often should couples have intercourse?
While there is no standard number of times a couple should have sex, studies have shown that those who have sex at least twice per week increase the probability of pregnancy. There is also research showing that long periods of abstaining from sex can decrease a man’s sperm quality.
Previously, there was a belief that there should be a waiting period before trying to get pregnant for women who have been taking birth control. This is no longer the accepted thinking. Now it is believed that there is no reason to delay attempting to conceive.
The timing of intercourse is more likely to impact the chances of pregnancy rather than how often intercourse takes place. Intercourse prior to ovulation is more likely to result in pregnancy.
