What should we do if we are diagnosed with hydrosalpinx when doing IVF? Hydrosalpinx can destroy the structure of the fallopian tubes, and even if they are patent, pregnancy may not be successful. If a tubal test before IVF indicates that the hydrosalpinx is connected to the uterus, the hydrosalpinx may back up into the uterine cavity during embryo transfer and affect the embryo transfer and cause the transfer to fail. Therefore, our doctors may recommend tubal ligation or salpingo-oophorectomy before IVF, and may also opt for tubal embolization to block the opening of the fallopian tube through hysteroscopy to avoid the backflow of the fluid in the fallopian tube. If the tubal effusion is still mild, it may also be possible to aspirate the tubal effusion before transferring the embryos, sometimes with better results.
