Women who have had normal pregnancies in the past may have problems with their fallopian tubes. Especially for women who have had an abortion or medication abortion, if pelvic inflammation occurs after the abortion, resulting in salpingitis or tubal blockage, hydrosalpinx, etc., it can cause abnormalities in the fallopian tubes. The fallopian tubes are the channels through which sperm and eggs are transported. If these problems occur in the fallopian tube, it will affect the probability of pregnancy and can lead to infertility or ectopic pregnancy. It is recommended to check the fallopian tubes for women who have been pregnant before but subsequently have not been able to conceive properly. If there are found to be blocked or incomplete fallopian tubes, tubal unblocking surgery can be attempted or an embryo transfer can be an option.
