The Prenatal Environment in Twin Studies: A Review on Chorionicity [PDF]

Behavior Genetics, 2016
A literature search was conducted to identify articles examining the association of chorionicity (e.g., whether twins share a single chorion and thus placenta or have separate chorions/placentas) and genetics, psychiatry/behavior, and neurological ...

Neonatal and developmental outcomes of very preterm twins according to the chorionicity and weight discordance

Scientific Reports, 2023
Perinatal outcomes of twin pregnancies are determined by several factors, such as gestational age (GA), chorionicity, and discordance at birth. This retrospective study aimed to investigate the association of chorionicity and discordance with neonatal ...

The impact of chorionicity and the type of twin growth on the early neonatal outcome in twin pregnancies – 20 years of experience from one tertiary perinatal center

Taiwanese Journal of Obstetrics & Gynecology, 2019
Objective: Twin pregnancies are associated with higher neonatal mortality and morbidity. Growth discordance and monochorionicity are among the factors that worsen the course of pregnancy.
