INFLUENCE OF THE INFERTILITY ETIOLOGY AND THE TYPE OF FOLLICULAR STIMULATION ON THE PREGNANCIES OBTAINED BY IN-VITRO FECUNDATION

During a retrospective study on 152 singles pregnancies obtained by in vitro fecondation at Tenon hospital, and followed in this department between January 1990 and December 1994, we have studied the influence of the IVF indications (tubal origin, masculine or idiopathic) and the type of stimulation (human menopausal gonadotrophin hMG or follicle s timulating hormone FSH) on the weight of the newborn and the pathologi es that occured during the pregnancy. No difference in the antecedents has been found in the different group of patients, This study shows a significative difference (p < 0,001) of the newborn's weight when the indication of IVF is tubal origin or masculin, Also, in all IVF indic ations, the weight is significantly (p < 0,01) higher after a follicul ar stimulation by FSH versus hMG. For the pregnancy pathologies, no si gnificative difference has been noted, although arterial hypertension, fetal growth retardation and gestational diabete appear to be more fr equent in the group of women who had a stimulation by hMG.
