Gamete Intra-Fallopian Transfer (G.I.F.T.)
After the eggs have been collected and
examined, they are mixed with the prepared sperm and transferred to the
fallopian tube.
Gametes are transferred to the fimbrial
end of the fallopian tube immediately
after ova aspiration.
Requirements:
- At least 10 million sperms per millilitre after preparation.
- At least 1 normal Fallopian tube.
- The production of 3 or more oocytes.
-
Hormone treatment (superovulation) to ensure the development of several
oocytes.
- Monitoring of follicular growth.
- Induction of ovulation.
-
The sperm sample is prepared approximately 2 hours before the aspiration
of the oocytes.
- Laparoscopic (general anaesthetic) aspiration of oocytes.
-
Transfer of 3-5 (mature) oocytes plus a sample of sperm into the upper
part of the fallopian tube.
- Pregnancy test (12-15 days after transfer).
Number of visits to centre:
7 to 10 per cycle for the female
2 visits for the male
Pregnancy chance: approximately 50% per cycle
GIFT is seldom practised nowadays as the IVF pregnancy rates are now
just as good or better.
