After the fallopian tubes are unblocked, pregnancy can be prepared in 1-3 months. Tubal adhesion and blockage are the main causes of female infertility. Because sperm and eggs must combine in the ampulla of fallopian tube to form fertilized eggs, which are displaced to the uterus through fallopian tube and finally implanted into the uterus to complete natural conception. Obstruction of one fallopian tube will greatly reduce the chances of conception, and obstruction of both sides will lead to infertility. Mild adhesion can be treated by tubal drainage, which has little effect on the body. After the next menstruation comes, you can prepare for pregnancy. For severe cases, hysteroscopy is used to separate tubal adhesions. This kind of damage is relatively large, and the repair needs a process, about three months. In addition, it is recommended to prepare oral folic acid tablets during pregnancy to prevent fetal neural tube dysplasia until the third month of pregnancy.
