Are sperm DNA fragmentation hyperactivation and hyaluronan binding ability predictive for fertilization and embryo development in in vitro fertilization and intracytoplasmic sperm injection

Thursday, March 28, 2013
Because DNA fragmentation, hyaluronan-binding ability, and induced hyperactivity of spermatozoa correlate with the fertilization rate after in vitro fertilization, blastocyst formation can be predicted by the sperm DNA fragmentation rate.

The Effect of Timing of Embryonic Progression on Chromosomal Abnormality

Thursday, September 27, 2012
In this study analyzing embryo morphology and chromosomal status in relation to rate of embryonic developmental progression, the ability to blastulate, rather than day of blastulation, was found to significantly affect aneuploidy.

Successful pregnancy in vitrified/warmed blastocyst intrafallopian transfer

Wednesday, June 6, 2012
Blastocyst intrafallopian transfer is a feasible option in cases of repeated difficult ETs, regardless of whether the patient shows cervical adhesions or any type of genital malformations.

Outcomes of singleton births after blastocyst versus nonblastocyst transfer in assisted reproductive technology

Wednesday, May 23, 2012
Retrospective cohort analysis of 4,202 births resulting from blastocyst versus nonblastocyst transfer demonstrated no significant difference in maternal and perinatal outcomes, although blastocyst transfer may increase preeclampsia and placenta previa.
