Monozygotic twinning associated with assisted reproductive technologies: a review.

TLDR
An improved understanding of the factors that contribute to increased MZ twinning associated with ART will help to elucidate the poorly understood mechanisms involved in the process and will further aid in reducing the overall incidence of multiple pregnancies with their associated risks following ART procedures.

Fecundity and twinning. A study within the Danish National Birth Cohort.

TLDR
A long TTP is associated with a reduced risk of twinning, and women not planning a pregnancy had a lower rate of opposite sex twins than planners, but a comparable rate of same sex twins.

On the origin of zygosity and chorionicity in twinning: evidence from human in vitro fertilization

TLDR
The current knowledge is documented, the accepted dogma is criticized, and new insights are proposed into the origin of zygosity and chorionicity are proposed.

The incidence of monozygotic twinning following PGD is not increased.

TLDR
The incidence of MZ twinning was not increased in PGD compared with regular ICSI with blastocyst transfer, and this information is useful in counselling patients about potential risks of PGD.

Twins born following fertility treatment: implications for quantitative genetic studies.

TLDR
The differences found between ART and NC twins on group means and twin correlations suggest that researchers should be aware that including ART twins may influence results from twin studies.

Twins Born Following Fertility Treatment: Implications for Quantitative Genetic Studies

TLDR
The differences found between ART and NC twins on group means and twin correlations suggest that researchers should be aware that including ART twins may influence results from twin studies.

An age-dependent ovulatory strategy explains the evolution of dizygotic twinning in humans

TLDR
It is shown that the most successful ovulatory strategy would be to always double ovulate as an insurance against early fetal loss, but to never bear twins, which supports the hypothesis that twinning is a by-product of selection for double ovulation rather than selection for twinning.

The mystery of monozygotic twinning II: What can monozygotic twinning tell us about Amyoplasia from a review of the various mechanisms and types of monozygotic twinning?

TLDR
Amyoplasia, a specific nongenetic form of arthrogryposis, appears to occur in spontaneous MZ twinning and may be related to twin–twin transfusion.

Prematurity and twinning

  • 2012
TLDR
Prevention of preterm birth is a primary goal in managing multiple pregnancies, together with prophylaxis with corticosteroids in order to improve foetal lung maturity and reduce the increasing need for neonatal intensive care and for health resources in the long-term follow-up.
