Blastocyst collapse is not an independent predictor of reduced live birth A time lapse study

Wednesday, June 1, 2016
Blastocyst collapse observed by time-lapse monitoring is not independently associated with a decreased chance of live birth; rather it is confounded by morphokinetic parameters that are stronger predictors of reproductive outcome.

Impact of single embryo transfer policy on perinatal outcomes in fresh and frozen cycles analysis of the Japanese Assisted Reproduction Technology registry between 2007 and 2012

Monday, February 1, 2016
Single embryo transfer (SET) policy improves perinatal outcomes in Japan. The impact of SET policy was different in fresh and frozen cycles for several perinatal outcomes.

Influence of different oocyte insemination techniques on early and late morphokinetic parameters Retrospective analysis of 500 time lapse monitored blastocysts

Thursday, October 29, 2015
In vitro fertilization–fertilized embryos developed with a 1.5-hour delay, which disappeared after standardization to pronuclear fading, thus permitting the joint analysis of standard IVF- and ICSI-fertilized embryo cohorts.

Single vitrified blastocyst transfer maximizes liveborn children per embryo while minimizing preterm birth

Monday, June 1, 2015
Single vitrified-warmed blastocyst transfer provides excellent live-birth rates and higher embryo to live-birth efficiency while minimizing preterm birth and low birth weight, relative to double transfer.

Predictive value of maternal serum human chorionic gonadotropin levels in pregnancies achieved by in vitro fertilization with single cleavage and single blastocyst embryo transfers

Monday, June 1, 2015
Mean human chorionic gonadotropin levels resulting from a single fresh blastocyst transfer were significantly higher than those from a single cleavage transfer after adjusting for confounding variables.

Monozygotic twinning after assisted reproductive technologies A case report of asymmetric development and incidence during 19 years in an international group of in vitro fertilization clinics

Wednesday, April 29, 2015
We report a case of monozygotic twinning with asymmetric development after a single-embryo transfer. We also estimate the incidence of monozygotic twinning in our IVF clinics.

Economic evaluation of elective single embryo transfer with subsequent single frozen embryo transfer in an in vitro fertilization intracytoplasmic sperm injection program

Friday, February 27, 2015
The choice of elective single-embryo transfer strategy to be adopted should be determined by the context of the health system and the individual prognosis.

Impact of assisted reproductive technology on the incidence of multiple gestation infants A population perspective

Monday, December 29, 2014
We discuss that in monitoring the safety and efficacy of fertility treatment, registration of the percentage of single embryo transfer cycles might not be sufficient and utilization should be taken into account as well.

Single embryo transfer of vitrified warmed blastocysts yields equivalent live birth rates and improved neonatal outcomes compared with fresh transfers

Wednesday, April 30, 2014
After 1,157 fresh and 645 vitrified-warmed day-5 single-blastocyst transfers, we found vitrified warmed blastocysts yielded equivalent birth rates and improved neonatal outcomes compared with fresh transfers.

Personalized medicine or one size fits all

Monday, March 31, 2014
As with other disease states, the goal of therapy for infertility should be the optimal management of the individual patient: a "one size fits all" approach would inevitably risk depriving some patients of effective treatment.

The impact of consumer affordability on access to assisted reproductive technologies and embryo transfer practices an international analysis

Tuesday, December 31, 2013
In this international econometric study of assisted reproduction technology treatment, we show that the cost that consumers pay for treatment relative to income predicts the level of access and number of embryos transferred.

Comprehensive chromosome screening alters traditional morphology based embryo selection a prospective study of 100 consecutive cycles of planned fresh euploid blastocyst transfer

Friday, August 30, 2013
A prospective series of 100 consecutive cycles using CCS demonstrated that the blastocyst selected by day 5 morphology has a substantial risk of aneuploidy.

Comprehensive chromosome screening of trophectoderm with vitrification facilitates elective single embryo transfer for infertile women with advanced maternal age

Friday, August 30, 2013
Comprehensive chromosome screening of trophectoderm with vitrification and later transfer in an unstimulated cycle may be the key to providing elective single-embryo transfer for the older woman undergoing IVF.

In vitro fertilization with single euploid blastocyst transfer a randomized controlled trial

Friday, June 28, 2013
The Blastocyst Euploid Selective Transfer (BEST) Trial demonstrated that single euploid blastocyst transfer results in ongoing pregnancy rates that are equivalent to transferring two untested blastocysts, while dramatically reducing the risk of multiple gestations.

Elective single embryo transfer trends and predictors of a good perinatal outcome United States 1999 to 2010

Friday, May 31, 2013
Elective single ET in the United States increased from 1999–2010. One-third of elective single ET among 35–37-year-olds resulted in a good perinatal outcome; transfer guidelines could be expanded.

Clinical factors associated with live birth after single embryo transfer

Thursday, November 1, 2012
Female age and blastocyst expansion are associated with live birth in patients undergoing SET. Many other clinical factors including obesity do not appear to affect SET outcome.

Elective single-embryo transfer

Thursday, May 10, 2012
The optimal outcome of in vitro fertilization is the birth of a healthy singleton. Elective single-embryo transfer should be offered to good-prognosis patients. Elective single-embryo transfer utilization should increase with improved awareness and embryology laboratory advances.
