One way women can induce favorable changes in cervical mucus is to take evening primrose oil during the first half of their menstrual periods. Evening primrose oil is a rich source of gamma-linolenic acid. This is an essential fatty acid that encourages the production of anti-inflammatory hormones. When the cervical mucus contains higher concentrations of anti-inflammatory hormones, sperm are more likely to be able to swim through it to the uterus. Many women find that the results of taking evening primrose oil are quickly evident as the cervical mucus obviously changes color, consistency, and odor. While evening primrose oil can be very helpful in supporting women's fertility, there are also theoretical reasons to be concerned that it could interfere with the implantation of the fertilized egg, and therefore induce abortion, if taken after conception. Evening primrose oil is known to stimulate uterine contraction.
If the uterus is not stable enough to support implantation of the fertilized egg, implantation cannot occur. That is why evening primrose oil is helpful during the first half of a woman's menstrual period. Since a woman won't know she is pregnant unless she misses her next period, it is always better to play it safe and avoid evening primrose oil after the middle of her period - just in case she and her partner conceived. Douches, by the way, do not solve any problems with cervical mucus. Healthy cervical mucus is essential for transporting the sperm where they need to go, and removing cervical mucus will not enhance a couple's chances of conception.
