Sometimes. Fibroids can cause infertility by damaging fallopian tubes, by affecting bleeding patterns during menstruation, or by causing inflammation in the uterus that prevents a pregnancy from growing well. Some fibroids are more likely to affect fertility, especially those in the muscle of the uterus or in the uterine cavity. Fibroids larger than 4-5 cm are also more likely to have a negative effect.
