Twins and their friendships: Differences between monozygotic, dizygotic same-sex and dizygotic mixed-sex pairs [PDF]

open access: yes, 2006
This study examined the influence of twin status (monozygotic [MZ], dizygotic same-sex [DZss] and dizygotic opposite-sex [DZos]) on friendship patterns. It examined the friendships of 60 children from 30 twin pairs, mean age 8 years, 4 months.

Placental plasticity in monochorionic twins: Impact on birth weight and placental weight [PDF]

open access: yes, 2015
INTRODUCTION The knowledge about adaptive mechanisms of monochorionic placentas to fulfill the demands of two instead of one fetus is largely speculative. The aim of our study was to investigate the impact of chorionicity on birth weight and placental

Single‐cell‐based non‐invasive screening for fetal pathogenic microimbalances using maternal blood: comparison with invasive prenatal diagnosis

open access: yesUltrasound in Obstetrics &Gynecology, Volume 67, Issue 4, Page 500-509, April 2026.
ABSTRACT Objective Pathogenic or likely pathogenic copy‐number variants (p/lpCNVs) are a significant cause of perinatal morbidity and mortality. Current prenatal screening based on cell‐free DNA (cfDNA) fails to detect the majority of microimbalances (microdeletions/microduplications), leaving a significant residual risk of undetected chromosomal ...

Amniocentesis and Risk of Fetal Loss in Dichorionic‐Diamniotic Twin Pregnancy: A Case‐Control Study

open access: yesPrenatal Diagnosis, Volume 45, Issue 6, Page 713-719, June 2025.
ABSTRACT Objective There is a paucity of data regarding the risk of fetal loss due to invasive prenatal diagnosis in twins. The aim of the present study is to assess the rate of amniocentesis‐related fetal loss in uncomplicated dichorionic‐diamniotic (DCDA) twin pregnancies. Methods Retrospective observational case‐control study.

Increased prevalence of congenital heart defects in monozygotic and dizygotic twins

open access: yes, 2013
BACKGROUND: Smaller studies and many case series reports indicate that congenital heart defects may be more common in monochorionic twins than in dichorionic twins and singletons.METHODS AND RESULTS: We investigated congenital heart defect occurrence in ...
