The fallopian tubes are two thin tubes, one on each side of the uterus. It helps lead the mature egg from the ovaries to the uterus. Blocked fallopian tubes are also a cause of infertility. Sperm and an egg meet in the fallopian tube and then they fertilize. A blocked tube can stop them from joining. If only one fallopian tube is blocked, then it won’t affect fertility because an egg can still travel through the unaffected fallopian tube. Fertility drugs increase your chance of ovulating on the open side of fallopian tube.

If your fallopian tubes are blocked by small amounts of scar tissue or adhesions, the fertility specialist can use laparoscopic surgery to remove the blockage and open the tubes. If your fallopian tubes are blocked by large amounts of scar tissue or adhesions, then treatment to remove the blockages may not be very helpful for successful natural conception and patients are advised to undergo IVF cycle.
