Many couples who are trying to conceive prefer to mix "medical" solutions, such as fertility drugs, with herbal or homeopathic remedies, such as Evening Primrose oil.
To understand how the two could work together, it is important to know what each one does. Clomid is the medication Clomiphene citrate. It is a hormone that tricks the pituitary gland into producing more of certain hormones called FSH and LH, which in turn stimulate the ovary. One of the side effects of Clomid is that it can cause hostile fertile mucous and thins the uterine lining in over 30 percent of the women who use it. The hostile mucus kills sperm, and the thin uterine can prevent implantation or cause an early miscarriage.
Evening Primrose Oil is purported to work specifically on the cervical mucus. It is thought to help you produce more egg white cervical mucus, the type that best aids sperm on its journey through the uterus and into the fallopian tube and to the egg. This is also the type of cervical mucus in which sperm can survive the longest before implantation. In this way, Evening Primrose Oil could potentially help with a side effect of Clomid.
There are no known problems with taking both Clomid and evening primrose oil together. As always, you should consult with your physician before beginning any herbal regimen.
