Can fibroids cause infertility?
The case of fibroids and infertility is controversial. A hysterosalpingogram may show that both tubes are open and that the fibroid is not interfering with the ability of sperm and egg to interact. Another possibility is a fibroid interfering with the implantation of the fertilized egg. This depends on the location, size and degree to which the fibroid is distorting the cavity. In cases of unexplained infertility (infertility of greater than 1 year with no known cause) removal of the fibroid has been proposed, but the literature is unclear as to the benefits. If ALL causes have been ruled out, then removal of the fibroid may be appropriate. However, the risks of scarring, which would cause more problems with infertility does exist. Therefore, surgery is a last resort. Other factors may be a bigger reason for difficulties with infertility.
Fibroids are not usually a cause of infertility. In order to cause infertility, fibroids must grow very close to and must actually obstruct the uterine openings of the Fallopian tubes, thereby blocking the passage of the egg as it enters the uterus. Both tubes must be blocked, since only one open tube is needed for pregnancy to occur.
