Incidence of complications among fertilization pregnancies.

The use of assisted reproductive technology has increased in Romania in the past several years. Although most of these pregnancies are uncomplicated, in vitro fertilization is associated with an increased risk for adverse perinatal outcomes primarily caused by the increased risks of prematurity, gestational diabetes mellitus, and hypertensive disorders. Infertility can be caused by a variety of factors, including both male and female factors, and in some cases, the cause remains unknown. In our clinic, the etiology of infertility was known in most cases and was equally distributed between male and female factors. Women with gestational hypertension were significantly older. Patients with twin pregnancies were significantly younger than those with a single pregnancy. The prevalence of preterm newborns was 2.5 times higher than the global prevalence for prematurity.
