GIFT

(Transfer intra-tubal of gametes)

The transfer intra-tubal of gametes (ovum with sample of sperm) or GIFT, in occasions is applied in infertile areas with success. The permeability of the tube in the woman should be verified. You can make the GIFT for via laparoscopy (through the abdominal wall) or for via trans uterine (through the vagina of the uterus). In the case laparoscopy, the ova are obtained by suction and they are deposited in a means of cultivation low observation microscopic. Then three mature ova are joined with a sample of sperm, previously prepared, in a thin stem and ova and sperm are deposited next to the tube, via laparoscopy. In the event of trans-uterine GIFT, the ova are obtained through a puncture of the vagina and later they are deposited in cultivation, low microscopic observation. They join the ova with the sample of sperm and they are introduced with a stem through the vagina and in the uterus in the tube.

The advantages of GIFT: they contact the ova the sperms, and the fertilization, the same as the first divisions, happen in a natural atmosphere, inside the trumpet. A disadvantage of GIFT is that in case the patient is not pregnant, you cannot determine a reason why the fertilization didn't happen.

The success of the method of GIFT is between a 10 and 40% and it depends mainly on the patient's age and of the quality of the sample of the semen. The dysfunctions in the hormones also influence the result.
