title: [Difficult embryo transfers: contribution of echography].
abstract: The aim of this retrospective study is to compare the results of embryo transfer in IVF without or after cervical dilatation, and trans-myometrial trans-vaginal transfer and after ultrasound-guided transfer. From 1989 to 1996 we have performed 4,355 embryo transfers to obtain 1,115 pregnancies. The results were 25.6% pregnancy by transfer and 10.9 embryos to start a pregnancy. During this time 281 transfers were appreciated as difficult or impossible and a cervical dilatation was done. We obtain 17.4% pregnancies by transfer with 16.5 embryos per pregnancy. We also practiced for the same indication 50 transmyometrial-transvaginal transfers. The result was 18% pregnancy by transfer and 16 embryos to start a pregnancy. In 1997 we have stopped cervical dilatations to prefer in these indications ultrasound-guided embryo transfer. 74 transfer were performed with this method to obtain 28.4% pregnancies per transfer and 9.9 embryos to start one pregnancy. This results are compared to a subgroup of women 38 years old or less, with a normal partner's sperm and in witch two embryos or more were transferred. At the end we think that the use of ultrasonography for embryo transfer is benefit in IVF program.
