Impact of fetal gender on risk of preterm birth

2 febrero 2015

Preterm birth, a delivery before 37 weeks of gestation, is one of the most serious obstetric complications affecting around 15 million pregnancies worldwide with more than one million newborn deaths each year due to complications of prematurity. So far, the underlying causes for preterm birth are still largely unknown. Preterm birth can either occur spontaneously or can be induced for medical reasons. There are various risk factors for preterm birth, of which a previous preterm birth is one of the most important. The gender of the unborn baby also seems to play a role in the process of being born prematurely.
