Prematuridade em gestações resultantes de fertilização in vitro

Abstract

A quantitative, descriptive, retrospective and documentary study is presented to evaluate the rate of premature births in pregnancies as a result from in vitro fertilization, using the Cryolife program for data collection, which is the program used by the clinic present in the research, for storage of patients' electronic medical records. The study was carried out in a human reproduction clinic in northern Paraná, where we established criteria to identify the index and possible causes of premature births in women with a prevalence of age from 34 to 38 years old who became pregnant through in vitro fertilization through the years from 2015 to 2019, using the technique of fresh embryo transfer or embryo thawing. In this period 156 babies were born, which 59.61% are male, 64.1% are from single gestation, 23% were born less than 37 weeks old and 33.3% were born weighing less than 2500kg. And relating to single and twin pregnancies, it was found that 50% of premature babies and 71.15% of babies born with low weight are twins. It is concluded that the rate of premature births in vitro fertilization is really high, however there was a predominance of single pregnancies during the human reproduction process in the 4 years evaluated.
