Some infertile couples are affected by conditions that prevent the sperm and egg from traveling through a fallopian tube, where fertilization and the first stage of cell division take place. The following are assisted reproductive technology (ART) procedures that are rarely used but may improve the chances of conception in the fallopian tubes. The first step of each of these treatment cycles is superovulation, the stimulation of multiple egg production with a series of hormone injections.

Gamete intrafallopian transfer (GIFT) uses multiple eggs collected from the ovaries, which are placed into a thin flexible tube (catheter) along with the sperm to be used. The gametes (both eggs and sperm) are then injected into the fallopian tubes using a surgical procedure called laparoscopy under general anesthesia.

The treatment process

For GIFT, the sperm are then placed in a tube (catheter) with the eggs. The catheter is inserted through a small abdominal incision and into a fallopian tube. The eggs and sperm are then injected into the fallopian tube. Usually, two eggs are placed in each fallopian tube.
