Gamete transfer

The term GIFT indicates the gamete transfer (ovum and spermazoo) inside the fallopian tube (gamete intrafallopian tube transfer). Although it begins in the same way as in IVF, with egg cells and sperms collected as in IVF, the technique differs in that the gametes are transferred back into the fallopian tubes almost immediately after collection. This means that fertilization by GIFT does not take place in vitro, but in its natural environment, represented by the fallopian tube. Let's see when this procedure can be done and how it works.

What is GIFT

The intratubal transfer of gametes is performed in various stages:



  1. echo-guided transvaginal or laparoscopic egg retrieval
  2. the removal of man's spermatozoa by masturbation
  3. the intratubal transfer of male and female gametes by laparoscopic or transvaginal route (ultrasound-guided or hysteroscopic).

The goal is to achieve fertilization where it occurs naturally, i.e. in the fallopian tubes.

The Gift requires laparoscopy and general anesthesia and can only be used in women with at least one intact fallopian tube.

When you do

We tend to perform the Gift for religious reasons, when the patients do not admit the use of IVF. The technique is not widely used as it is expensive (requires a hospital stay) and carries the risk associated with general anesthesia. Furthermore, one can never be sure that fertilization actually occurs.



About 25-30% of women usually become pregnant in one of the Gift treatment cycles; however, many centers do not practice this procedure as it results in a high rate of multiple pregnancies.
