triplets are seldom and monozygotic triplets are scarcely seen in humanity. There are few reports on triplets at home and abroad and diagnosis of zygosity is rarely made. We did the analysis of clinical material on two sets of triplets. Diagnosis and analysis of zygosity were made in eleven ways about 57 items including blood type and RBC enzyme type, etc.

Demographic and Assisted Reproduction Related Factors Associated with Dichorionic Triplet Gestations

Our objective was to evaluate which demographic factors or assisted reproductive technologies were associated with IVF triplet gestations where one of the embryos split, resulting in a dichorionic triplet gestation. This was a case-control study of dichorionic versus trichorionic triplet gestations that underwent assisted reproductive technology over the last 5 years at our fertility center. There were 53 cases of dichorionic triamniotic triplet gestations compared to 119 trichorionic triplet controls. There were no significant demographic differences between the cases and controls. 51/53 dichorionic triplets and 86/119 trichorionic triplets were conceived through IVF, the remaining utilized intrauterine insemination. ICSI was performed in virtually all patients that underwent IVF. Of the potential risk factors studied, hatching was used in 70.6% of dichorionic compared to 89.5% of trichorionic IVF triplets (p = 0.005);embryo transfer was performed on Day 5 or 6 compared to Day 3 in 88.0% dichorionic vs 71.8% trichorionic (p = 0.028). Frozen sperm was utilized more frequently with dichorionic than with trichorionic triplets, 26.0% vs 10.9% (p < 0.011). Only 4 (7.5%) of the IVF cases underwent pre-implantation genetics. Certain assisted reproductive technologies appear to be associated with embryo splitting and a dichorionic triplet gestation. More research is needed in this area to further elucidate these findings.
