The aim of this study was to analyze the incidence of stage of embryonic development, embryo quality and the time of transfer on pregnancy rate in embryo transfer program timed. We were worked a total of 23Holsteincowsasembryo donors, super-ovulated with gonadotropin of pregnant mare serum (PMSG) (2500 3000UI).69 cows were used as recipients of Holstein dairy heifers with an age of20 months and...

STUDY QUESTION Does atosiban (oxytocin/vasopressin V1A receptor antagonist), given around embryo transfer improve the live birth rate of women undergoing IVF treatment? SUMMARY ANSWER The use of atosiban around embryo transfer did not improve the live birth rate in a general population of IVF patients. WHAT IS KNOWN ALREADY Uterine contractions in IVF cycles were significantly increased fol...

The authors describe a rare case of secondary abdominal pregnancy after in vitro fertilization pre-embryo transfer (IVF-ET). Ultrasonography was applied to image ectopic gestational sac containing a yolk vesicle and located adjacent to the anterior uterine wall and left adnexa. Laparoscopy was done on the same day followed by sinistral salpingectomy due to tubal abortion indications. Intraabdom...

Although much is known about the embryo during implantation, the architecture of the uterine environment in which the early embryo develops is not well understood. We employed confocal imaging in combination with 3D analysis to identify and quantify dynamic changes to the luminal structure of murine uterus in preparation for implantation. When applied to mouse mutants with known implantation de...

BACKGROUND In order to optimize IVF strategies, particularly with the use of single embryo transfer, good predictive models are required. Here, we develop a model to allow such prediction, and the structure of the models point to more general conclusions about the mode of action of prognostic factors. METHODS Anonymized data from consecutive embryo transfers in five IVF centres in the UK for ...

The prevalence of diabetes is increasing worldwide with the trend of patients being young and creating a significant burden on health systems, including reproductiveproblems,but theeffectsofdiabeteson embryo implantation are still poorly understood. Our study was to examine effects of diabetes on mouse embryo implantation, providing experimental basis for treating diabetes and its complications...

Background: Embryo implantation is a complex biological process which requires synchronized dialogue between the receptive endometrium and blastocyst. The endometrium, however, only to embryo for very short period. Recurrent failure (RIF) major challenge in assisted reproductive techniques mainly due impaired receptivity, but there still need reliable valid clinical test assess endometrial rece...

Recent evidence describing a suboptimal clinical outcome in women with hydrosalpinges who undergo in-vitro fertilization (IVF) and embryo transfer suggests a potential deleterious effect of this fluid on in-utero embryo development. Consequently, we evaluated in-vitro mouse embryo development in the presence of hydrosalpingeal fluid (HF) collected from 10 infertile women of reproductive age. Ch...
