Influence of the insemination method on the outcomes of elective blastocyst culture

Although the fertilization method had no effect on clinical outcomes, the blastocyst formation rate and embryo utilization rate in the ICSI group were significantly lower than those observed in the conventional IVF group.

Effects of ovarian stimulation on oocyte development and embryo quality

Clear evidence is provided that ovarian stimulation does negatively impact the embryo and subsequent offspring and support is provided for an LH ceiling threshold, above which detrimental effects occur, both on in vitro embryo development and in vivo foetal development, which later effects postnatal growth.

Mitochondrial DNA copy number in cumulus cells is a strong predictor of obtaining good-quality embryos after IVF

The determination of mtDNA content in CCs can be used to predict good-quality embryos, and this tool was established by using cumulus cells (CCs) or peripheral blood cells (PBCs) in patients undergoing IVF.

Asynchronous division at 4–8-cell stage of preimplantation embryos affects live birth through ICM/TE differentiation

It was found that asynchronous embryos during the 4–8-cell stage were predisposed to be aborted, which could make synchrony a universal indicator common to all animal species.

Human Menstrual Blood-Derived Mesenchymal Cells Improve Mouse Embryonic Development.

An easy, noninvasive, and autologous method that could potentially increase blastocyst growth rates during assisted reproductive procedures (i.e., in vitro fertilization) and enriches the embryonic microenvironment and promotes embryo development is described.

Absence of CD9 reduces endometrial VEGF secretion and impairs uterine repair after parturition

It is found that CD9-mediated VEGF secretion plays a role in re-epithelialization of the uterus, and vascular endothelial growth factor (VEGF) was remarkably reduced in the uterine secretions of Cd9−/−TG female mice.

Search for morphological indicators that predict implantation by principal component analysis using images of blastocyst

This study compared blastocysts that showed elevated human chorionic gonadotropin levels after transplantation and those that did not and revealed that the hCG-positive group had grainy morphology and the h CG-negative group had non-grainy morphology, which will enhance current reproductive technologies.

Interleukin (IL)-1 Beta and IL-6 Levels in Human Embryo Culture Supernatants and their Role in Implantation Following IVF: A Prospective, Non-randomized Study

The aim of the present prospective, non-randomized study was to explore whether the measurement of IL-1β and IL-6 secretion by blastocysts could serve as a non-invasive method to predict blastocyst implantation competence following in vitro fertilization (IVF).



Single blastocyst transfer: a prospective randomized trial.

In vitro fertilization with single blastocyst-stage versus single cleavage-stage embryos.

Findings support the transfer of a single blastocyst-stage (day 5) embryo in infertile women under 36 years of age.

The successful use of pronuclear embryo transfers the day following oocyte retrieval.

The data show that oocyte quality and pronuclear embryo morphology are related to implantation and that pronuclear embryos can be successfully selected for embryo transfer.

Randomized single versus double embryo transfer: obstetric and paediatric outcome and a cost-effectiveness analysis.

The SET strategy is superior to the DET strategy, when number of deliveries with at least one live-born child, incremental cost-effectiveness ratio and maternal and paediatric complications are taken into consideration.

Elective single embryo transfer in women aged 36-39 years.

The eSET policy can be applied also to patients aged 36-39 years, reducing the risk of multiple birth and increasing the safety of assisted reproduction technique (ART) in this age group.
