“…Previously, several cases of monozygotic triplets following IVF have been reported in which ICSI [5, 7, 10], assisted hatching [5, 7], blastocyst transfer [6, 9], or frozen embryo transfer [8, 9] were the risk factors for the monozygotic triplet occurrence. It is noteworthy that in contrast to these case reports, in our case monozygotic splitting into triplets occurred without any of the known risk factors previously discussed.…”

“…Numerous studies indicate that monozygotic twinning rates following ART procedures are between two and twelve times higher than the natural occurrence of 0.4% [1–4]. Several cases of monozygotic triplets as a result of ART procedures have also been reported [5–10]. The reason for the increased incidence of monozygotic twinning after ART has been a matter of debate for a long time and there is no definite explanation.…”

Background. Assisted reproductive technology has been linked to the increased incidence of monozygotic twinning. It is of clinical importance due to the increased risk of complications in multiple pregnancies in general and in monozygotic twins in particular. Case. A 29-year-old female, nulligravida underwent her first IVF cycle. Three poor-quality cleavage stage embryos were transferred resulting in monochorionic triamniotic triplets and dichorionic diamniotic twins. Selective embryo reduction was performed at 12 weeks leaving dichorionic twins. The patient underwent emergency cesarean section due to preterm labor and nonreassuring fetal heart tracing at 30 weeks of gestation. Conclusion. Our case emphasizes that even embryos with significant morphological abnormalities should be considered viable and the possibility of simultaneous spontaneous embryo splitting must be factored into determining number of embryos to transfer.

“…A division between the 3rd and 8th days is the most frequent mechanism leading to high-order multiple pregnancies with, at least, a monochorionic biamniotic or triamniotic pregnancy (1)(2)(3)(4). However, in our case, a very early division (before the third day of development), in addition in both embryos, would have to have occurred to give bichorionic diamniotic monozygotic twins and/or trichorionic triamniotic monozygotic triplets.…”

“…Limiting the number of embryos transferred is one of the precautions. However, even if the number of transferred embryos is reduced, high-order multiple pregnancies can be observed (1)(2)(3)(4)(5). When the mechanism is uncertain, DNA analysis may be helpful.…”

Gestación gemelar monocigótica; Técnicas de reproducción asistida; Fecundación in vitro; Microinyección intracitoplasmáticaResumen La frecuencia de gestaciones gemelares monocigóticas se estima entre 0,4-0,45% de las gestaciones espontáneas. Sin embargo, tras la utilización de técnicas de reproducción asistida (TRA) numerosos estudios han demostrado un aumento del riesgo de gestaciones monocigóticas.A propósito de 2 casos presentados recientemente en nuestro servicio, planteamos una revisión de los posibles factores que se pueden asociar entre las TRA y la gestación múltiple monocigótica. ß 2013 SEGO. Publicado por Elsevier España, S.L.U. Todos los derechos reservados.Abstract Monozygotic twin pregnancies account for about 0.4%-0.45% of nonstimulated in vivo conceptions. However, numerous studies have demonstrated that the risk of these pregnancies is increased after the use of assisted reproductive technologies.We report two cases of monozygotic twin pregnancies that occurred recently in our hospital and review the possible factors that may be involved in the association between assisted reproductive technologies and monozygotic twin pregnancies.
