The aim of this study was to define pregnancy rates for gamete intra-F
allopian transfer (GIFT) with respect to the ovary from which most ooc
ytes were collected (i.e. a gross index of ovarian stimulation) and th
e Fallopian tube (ipsilateral or contralateral) into which gametes wer
e replaced. The only inclusion criterion was the ability to transfer g
ametes into the Fallopian tubes at GIFT. No other factors that could i
nfluence outcome were considered. In this retrospective review of the
clinic's database, no relationship was found between pregnancy rate an
d placement of gametes into the Fallopian tube coincident with the ova
ry from which most oocytes were collected. Thus when performing unilat
eral tubal transfer at GIFT gametes may be returned to the side most c
onvenient to the operating surgeon without fear of compromising pregna
ncy potential.
