Transfer of gametes into the fallopian tubes--is choice of side important?
The aim of this study was to define pregnancy rates for gamete intra-Fallopian transfer (GIFT) with respect to the ovary from which most oocytes were collected (i.e. a gross index of ovarian stimulation) and the Fallopian tube (ipsilateral or contralateral) into which gametes were replaced. The only inclusion criterion was the ability to transfer gametes into the Fallopian tubes at GIFT. No other factors that could influence outcome were considered. In this retrospective review of the clinic's database, no relationship was found between pregnancy rate and placement of gametes into the Fallopian tube coincident with the ovary from which most oocytes were collected. Thus when performing unilateral tubal transfer at GIFT gametes may be returned to the side most convenient to the operating surgeon without fear of compromising pregnancy potential.
