Infertility is when one is unable to get pregnant after six to 12 months of regular sexual intercourse without the use of any birth control. Infertility can be caused by a blockage in the fallopian tubes where the eggs travel from the ovaries to the uterus. Fallopian tube recanalization (unblocking) is performed using X-ray images. The interventional radiologist will place a small catheter through the cervix, into the uterus and fallopian tubes to clear the blockage. Most patients can resume their normal activity the day of discharge and guidance will be provided on post treatment care.
