The association of crown‐rump length discrepancy with birthweight discordance in spontaneous versus IVF monochorionic twins: a multicenter study

Abstract

The significant correlation between CRL discrepancy and birthweight discordance in spontaneous versus IVF MC twin pregnancies might suggest differential monozygotic twinning process.

Assisted reproductive technology and risk of adverse obstetric outcomes in dichorionic twin pregnancies: a systematic review and meta-analysis

“…Monochorionic twins constitute up to one-third of all twin gestations (57). With the expansion of ART, there has been an increase in the incidence of monozygotic twinning (58,59).…”

Monochorionic diamniotic in vitro fertilization twins have a decreased incidence of twin-to-twin transfusion syndrome

“…During the study period, a total of 337 women were diagnosed with MC diamniotic twin pregnancy. Some of them took part in our previous study (17). Ten of these pregnancies (3%) that were conceived after non-IVF fertility treatments were excluded from the study group.…”

“…Recently, we have shown a significant correlation between CRL discrepancy and birthweight discordance in spontaneously conceived MC twins, as opposed to IVFconceived MC twin pregnancies (17). We hypothesized that this difference reflects different biological processes of MZ twinning of spontaneous versus IVF-conceived twins (17). When performing an 11-14 weeks scan to determine chorionicity (14,15), we aim to disclose the zygosity.…”

Pre-Twin Screen - A Multi-Disciplinary Approach for a Personalized Prenatal Diagnostics and Care for Twin Pregnancies

“…Mathematical models [40,41] are implemented, and surveillance and prevention models will be offered. As will be further described in the methodology -the larger the risk, the earlier will be the GA at delivery, adding to the increase burden of prematurity [42][43][44][45][46][47][48][49][50].…”
