G.I.F.T. What is G.I.F.T. This is an alternative techniques
for treating infertility. G.I.F.T. stands for Gamete Intra-Fallopian Transfer.
The word gamete refers to the sex cells, i.e. both eggs and sperm.
How does the G.I.F.T. method work In the G.I.F.T. method, eggs are
retrieved from the ovaries as in I.V.F. using either laparoscopy or T.U.D.O.R.
These eggs are then transferred with a specially prepared sperm sample
into the outer fimbrial opening of the fallopian tube by laparoscopy under
a general anaesthetic.
What are the advantages of G.I.F.T. The advantage that G.I.F.T. offers
is that it allows fertilisation to take place naturally within the fallopian
tube with a higher chance that implantation will also occur naturally.
The obvious requirement is that the tubes must be patent and healthy. G.I.F.T.
therefore offers an alternative treatment to couples where I V.F may have
been the only other option.
What other treatments involve injection of sperm In addition to G.I.F.T., other techniques
that involve the injection of sperm alone, or with retrieved eggs into
the peritoneal cavity via the vagina, such as V.I.S.P.E.R. (Vaginal Injection
of Sperm Peritoneally) are at present being evaluated. It is hoped that
techniques such as V.I.S.P.E.R. will be more straightforward to perform
than G.I.F.T., and will, if performed under the control of ultrasound guidance
alone, remove the need for a general anaesthetic, which is always associated
with laparoscopy.
