12 lis 2015 · In this article, we report two further cases of high order monozygotic pregnancies following ART: one monochorionic quadramniotic (MCQA) quadruplet pregnancy following ICSI and embryo biopsy for pre-implantation genetic diagnosis (PGD) and one monochorionic triamniotic (MCTA) triplet pregnancy following conventional IVF.
Monozygotic triplet pregnancies are very rare, even after in vitro fertilization (IVF). We present a case of a live birth of triplets from a monochorionic triamniotic pregnancy after blastocyst transfer. A 29-year-old woman underwent intracytoplasmic sperm injection (IVF-ICSI).
At 6 weeks and 5 days of gestation, an ultrasound revealed monochorionic triamniotic (MCTA) triplets with three yolk sacs and three fetal poles. The cardiac activity was visible only for two fetal poles (Figure 1).
Twins, in rarer cases triplets, quadruplets (four), quintuplets (five), arising from a single fertilized ovum are termed monozygotic (MZ). The first identical quintuplets known to have survived their infancy were the Canadian Dionne quintuplets, all five of which survived to adulthood ( Fig. 3.1 ).
23 cze 2020 · Our case report of repeated triplets with monochorionic twins suggests the potential causes and risk factors of monochorionic twinning in assisted reproduction and raises concern regarding the timing of multifetal pregnancy reduction.
1 sty 2020 · Since monozygotic and monochorionic triplets (Fig. 2.16) and quadruplets undoubtedly exist (MacArthur and MacArthur, 1937, Steinman, 1998) (Fig. 2.17), three major questions arise. First, given Corner’s theory for monozygosity in twins, how are higher-order multiples formed?
1 maj 2024 · Monochorionic-triamniotic (MCTA) triplet pregnancies following artificial reproductive technologies are uncommon. We report a case in which one of two transferred embryos differentiated into an MCTA triplet. This study aimed to investigate the potential factors contributing to MCTA triplet pregnancy. Case report.
