Research progress on influencing factors and related mechanisms of birth weight in offspring of assisted reproductive technology
With the increase of the incidence rate of infertility,assisted reproductive technology(ART)has gradually become the main or even the only treatment for infertile people.A large amount of evidence showed that perinatal outcomes of ART offspring are different from those of naturally conceived offspring,such as the increased risk of low birth weight and long-term metabolic abnormalities.However,beside of ART,infertility and the fetus factor also play a role in the poor pregnancy outcome.Since birth weight plays an important role in the long-term health of newborns,this article reviewed the factors and related mechanisms that may affect the birth weight of offspring conceived by ART,so as to contribute improving the pregnancy outcome.
