Fibroids, are non-cancerous (benign) growths that develop in or on the uterus. They can interfere with pregnancy in many ways. The ones that grow on the inside wall of your uterus can cause changes in the endometrial tissue, making it difficult for an embryo to develop and attach to the uterus. Fibroids that develop outside the uterine wall grow in thin stalks that can compress or block the fallopian tubes, thereby preventing the sperm from reaching the egg.
Symptoms of Fibroids
The severity of your symptoms will depend on the number, size, and location of the fibroids. Fibroids often cause no symptoms, unless they grow large enough to press painfully on other organs. You may experience heavy bleeding between or during your periods, pain in the pelvis and lower back, increased menstrual cramping, pain during intercourse and increased urination.
Cause of Fibroids
The cause of uterine fibroids is unknown, but they require estrogen to grow. They often shrink after menopause, when estrogen levels decrease. Fibroids may run in the family if your mother, sister or grandmother has a history of this condition, you could develop it as well. Pregnancy increases the production of estrogen and progesterone in your body. Fibroids may develop and grow rapidly when you are pregnant.
