Many women ask if fibroids can affect fertility. The answer is rather complicated, first of all, in terms of the causes of infertility, fibroids hardly affect fertility, but submucosal fibroids can’t be said to have no effect on pregnancy because they affect the internal environment of the uterus; and the effect of fibroids on pregnancy mainly affects the process of pregnancy, such as the degeneration of fibroids may occur during pregnancy, the special position of the tumor may interfere with the fetal position during pregnancy, and the obstruction of the birth canal during delivery may cause obstructed labor, etc. The tumor may interfere with the fetal position during pregnancy, and may obstruct the birth canal during delivery, causing obstructed labor. Therefore, if fibroids are found before pregnancy and their maximum diameter exceeds 4 cm, they should be removed before pregnancy! It will facilitate the process of pregnancy and will obviously reduce the occurrence of redness of fibroids during pregnancy; if you have fibroids and the amount of fibroids is large, as long as there are no other causes of infertility detected, you can operate regardless of the number of tumors and regardless of the size of the tumors, we have treated some cases with 300-400 fibroids on the uterus, and there have been many cases of successful pregnancy after treatment. However, due to the excessive incisions and scarring on the uterus, trial of labor is usually not dared and delivery by cesarean section is mostly used.
