title: [Interconnection between assisted reproductive technologies, pregnancy complications and risk of birth defects].
abstract: The aim of the article was to investigate the relationship between pregnancy complications, infertility and assisted reproductive technologies (ART). The study was conducted on 1331 couples with complicated reproductive history. It is found that miscarriage and other complications of pregnancy depend rather on the etiopathogenesis of infertility than on the technique of ART. The highest frequency of complications of pregnancy was diagnosed in women with endocrine disorders. In case of congenital malformations in the fetus the frequency of birth defects was 3.6% after in vitro fertilization (IVF) and 1.8% in case of spontaneous pregnancy. It was found an increased risk of birth defects in singleton boys conceived by IVF.
