Effect of embryo morphology and morphometrics on implantation of vitrified day 3 embryos after warming: a retrospective cohort study
BACKGROUND Characteristics routinely used to evaluate embryo quality after thawing include number of blastomeres survived and presence of mitosis resumption after overnight culture. It is unknown to which extent symmetry and fragmentation affect implantation after warming and whether application of stricter criteria either before vitrification or after warming would improve implantation rate (I...
متن کاملDetermination the Effects of Epidermal Growth Factor on Developmental Rates of Pre-Implantation Mouse Embryo
Purpose: To determine the effects of different doses of addition of exogenous epidermal growth factor (EGF) on development of pre-implantation mouse embryo. Materials and Methods: Mouse zygotes, two cell, 8 cell any morulae were collected from superovulated NMRI mice 24, 48, 64 and 80 hrs after hCG injection, respectively. The obtained embryos were cultured on medium alone, medium with 1, 4 an...
متن کاملIs there a link between blastomere contact surfaces of day 3 embryos and live birth rate?
BACKGROUND Cell-cell communication and adhesion are essential for the compaction process of early stage embryos. The aim of this study was to develop a non-invasive objective calculation system of embryo compaction in order to test the hypothesis that embryos with a larger mean contact surface result in a higher live birth rate compared to embryos with a lower mean contact surface. METHODS Mu...
متن کاملEffect of Embryo Banking on U.S. National Assisted Reproductive Technology Live Birth Rates
BACKGROUND Assisted Reproductive Technology (ART) reports generated by the Centers for Disease Control and Prevention (CDC) exclude embryo banking cycles from outcome calculations. METHODS We examined data reported to the CDC in 2013 for the impact of embryo banking exclusion on national ART outcomes by recalculating autologous oocyte ART live birth rates. Inflation of reported fresh ART cycl...
متن کاملImpact of Endometrial Preparation Protocols for Frozen Embryo Transfer on Live Birth Rates
BACKGROUND It has been reported that a natural cycle (NC) is similar to or even better than hormone replacement therapy (HRT) in patients with regular cycles who undergo frozen embryo transfer (FET). Hundreds of FETs are managed yearly in our clinic. Scheduling these cycles is critical in a busy unit like ours. This is why we have to prove if a NC really shows a better outcome than other endome...
