[Perinatal outcome in multiple pregnancy after natural reproduction and ART techniques].

In this study we analysed occurrence of multifetal pregnancy in groups of patients after natural reproduction and after using ART between 1991-1998 in clinical material. We showed the most important complications during pregnancy, occurrence of TTTS, percentage of prematurity, percentage and indications to caesarean sections. We found that above-mentioned manifestations of perinatal care were comparable with reports of Polish and foreign authors.
