Uterine fibroids are mainly composed of smooth muscle and connective tissue and are most common in women of childbearing age. The impact on pregnancy varies greatly depending on the size, number, and location of the fibroids. If the fibroids are small, they do not affect the fertilization of the egg, the growth and development of the embryo, or the entry of sperm, so it is possible to prepare for pregnancy. If a woman has a large fibroid, it may have an impact on her pregnancy, because the hormonal stimulation after pregnancy will continue to increase the size of the fibroid, and the fibroid will affect the contraction of the uterus, so it may affect the fertilization of the egg, or even affect the growth and development of the fetus after pregnancy, and cause a spontaneous abortion, so for this type of women often need to consider surgery to remove the fibroid, and then Therefore, for these women, surgery is often necessary to remove the fibroids and then prepare for pregnancy. In the case of fibroids in special areas, such as submucosal fibroids, cervical fibroids and broad ligament fibroids, they may affect pregnancy to a certain extent and need to be treated relatively actively before preparing for pregnancy.
