title: [Preterm deliveries after in vitro fertilization treatment of infertility].
abstract: Wide access to the assisted reproductive technics as a tool in the treatment of infertility arisen many questions regarding the outcome of the pregnancy, its possible complications and the neonatal outcome in women after IVF treatment. We completed the literature search in order to present this subject. It seems that the increased rate of spontaneous abortions and preterm deliveries in this group is caused by such factors as: maternal age, chromosomal, hormonal and uterine abnormalities and immunological factors. The incidence of preterm deliveries in the multiple gestation after IVF group is similar to the one observed in the spontaneous pregnancy group.
