Importance of embryo transfer technique in maximizing assisted reproductive outcomes
Friday, April 1, 2016
Meticulous ET technique, aided by ultrasound guidance, is essential to optimal outcomes with assisted reproductive technology.Examining the many potential reasons why euploid blastocysts do not always result in viable pregnancies and deliveries Part 2
Friday, April 1, 2016
A viable delivery requires optimal embryo transfer technique, a receptive and synchronized endometrium, a physiologically and anatomically adequate uterus, and absence of local and circulating factors capable of disrupting implantation.Local and systemic factors and implantation What is the evidence
Friday, April 1, 2016
Some medical conditions and lifestyle factors can influence implantation in the setting of IVF. Multiple endometrial and circulating factors affecting implantation will be reviewed.Time lapse deselection model for human day 3 in vitro fertilization embryos The combination of qualitative and quantitative measures of embryo growth
Tuesday, March 1, 2016
This study presents a deselection model for human in vitro fertilization embryos independent of the insemination method, the qualitative component being more accurate when coupled with a quantitative component.Optimal polar bodies angle for higher subsequent embryo viability A pilot study
Tuesday, March 1, 2016
Noninvasive assessment of polar bodies angle proves to be a practical tool for the selection of viable embryos and should be considered for inclusion in embryo selection parameters.Morphokinetic analysis and embryonic prediction for blastocyst formation through an integrated time lapse system
Monday, February 1, 2016
Blastocyst formation and implantation prediction based on late morphokinetic parameters was developed by using an integrated time-lapse monitoring system.Differential expression of vascular endothelial growth factor angiogenic factors in different endometrial compartments in women who have an elevated progesterone level before oocyte retrieval during in vitro fertilization Embryo transfer treatment
Tuesday, September 29, 2015
Altered expression of vascular endothelial growth factor angiogenic factors in peri-implantation endometrium may provide an explanation for the impairment of endometrial receptivity in women who have high P levels before oocyte retrieval.Mitochondrial DNA content as a viability score in human euploid embryos Less is better
Tuesday, September 1, 2015
Higher mitochondrial DNA content in euploid human embryos is related to poor implantation potential and may be indicative of reduced metabolic fuel during oocyte maturation.Autologous endometrial coculture biopsy Is timing everything
Monday, June 29, 2015
Coculture biopsy in the cycle preceding IVF does not increase implantation, clinical pregnancy, or live birth rates compared with biopsies performed more than one cycle before IVF.Are good patient and embryo characteristics protective against the negative effect of elevated progesterone level on the day of oocyte maturation
Monday, June 1, 2015
Elevated P level on the day of human chorionic gonadotropin administration negatively affects live-birth rate, regardless of embryo stage, embryo quality, patient age, or ovarian response.External validation of a time lapse prediction model
Monday, March 30, 2015
This external validation study failed to replicate the performance of the time-lapse published prediction model, but it should inspire each center to build its own prediction model.Antimullerian hormone as predictor of implantation and clinical pregnancy after assisted conception A systematic review and meta analysis
Monday, December 29, 2014
Antimullerian hormone has weak association with implantation and clinical pregnancy rates in women undergoing ART, but its predictive ability for pregnancy rates is greatest in women with diminished ovarian reserve.Prevalence consequence and significance of reverse cleavage by human embryos viewed with the use of the Embryoscope time lapse video system
Monday, July 14, 2014
This study investigated the prevalence and significance of reverse cleavage by human embryos observed via time-lapse monitoring. Embryos showing reverse cleavage were associated with compromised subsequent development and implantation potential.Clinical validation of embryo culture and selection by morphokinetic analysis A randomized controlled trial of the EmbryoScope
Wednesday, July 9, 2014
An alternative strategy for embryo selection based on a multivariable morphokinetic model combined with continuous incubation in an integrated timelapse monitoring system improves the clinical results.Casting for determinants of blastocyst yield and of rates of implantation and of pregnancy after blastocyst transfers
Monday, June 30, 2014
Numbers of oocytes retrieved and properties of day 3 embryos were predictive of blastocyst formation, implantation, and pregnancy. Patient age and oocyte yields independently impacted implantation rates and uterine receptivity.Peri implantation intercourse lowers fecundability
Wednesday, June 25, 2014
Two or more acts of intercourse during the peri-implantation window is associated with a lower probability of pregnancy given prior intercourse during the fertile window.Prospective assessment of midsecretory endometrial leukemia inhibitor factor expression versus ανβ3 testing in women with unexplained infertility
Sunday, June 1, 2014
Epithelial LIF expression is reduced in the endometrium of women with UI and is superior to avb3 integrin alone for assessment of endometrial receptivity.MicroRNAs and implantation
Sunday, June 1, 2014
This review discusses diagnostic and therapeutic roles of miRNA in implantation. Although promising, further research is needed before miRNA are used in clinical practice for identifying and treating implantation failure.Regulation of myeloid ecotropic viral integration site 1 and its expression in normal and abnormal endometrium
Friday, May 23, 2014
Myeloid ecotropic viral integration site 1 (MEIS1) was expressed in response to sex steroid in the endometrium both in vitro and in vivo. Diminished endometrium MEIS1 expression may contribute to implantation failure in endometriosis.Association of physical activity in the past year and immediately after in vitro fertilization on pregnancy
Monday, March 31, 2014
Higher self-reported past year physical activity was associated with favorable pregnancy outcomes following in vitro fertilization (IVF). Physical activity and sedentary behavior following IVF were not associated with pregnancy outcomes.
