Can Uterine Fibroids Cause Infertility?



Among the causes of female infertility is a condition which affects 5-10% of women who are infertile. A single muscle cell in the uterine wall multiplies and grows into a noncancerous tumor. This is a uterine fibroid. They are also known as myomas or leiomyomas. These growths can change the size or shape of the uterus. They may also affect the cervix. There are cases where a woman may only have one fibroid, but there are usually more than one. The location, size and number of fibroids can affect a woman’s ability to conceive.

Fibroids affect fertility by:

- changing the shape of the cervix so that the number of sperm entering the uterus is reduced

- changing the shape of the uterus so that the movement of the sperm or embryo is impaired

- blocking the fallopian tubes

- impacting the size of the lining of the uterine cavity

- impacting the blood flow to the uterine cavity so that the embryo cannot properly implant on the uterine wall .
