Is 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 کاملClinical pregnancy and live births after transfer of embryos vitrified on day 3.
Human embryo vitrification is a promising new technology but clinical outcome data is needed to gauge its effectiveness and safety. While pregnancy and live-birth data is available for blastocyst vitrification, such information is lacking for human embryo vitrification at the 6- to 8-cell stage. The current work presents clinical and obstetric outcomes from the transfer of embryos vitrified on ...
متن کاملsuccessful pregnancy following the transfer of vitrified blastocyst which developed from poor quality embryos on day 3
background: the selection of pre-embryos for transferred is based on morphological appearance. but some poor quality cleaved embryos also can be cultured to the blastocyst stage and implanted. objective: to assess the clinical pregnancy outcomes of blastocyst transfer which developed from poor quality embryos. materials and methods: a total of 109 cleaved embryos with poor quality were cultured...
متن کاملLive birth after fresh versus frozen single blastocyst transfer (Frefro-blastocyst): study protocol for a randomized controlled trial
BACKGROUND Multiple pregnancies are one of the major safety concerns of in vitro fertilization (IVF) due to the increased risk of maternal and neonatal complications. Single embryo transfer is the most effective way to reduce the risk of multiple pregnancies. Selection of the embryo and optimization of the implantation environment are crucial to retain the success rate when the number of transf...
متن کاملAssisted hatching of poor-quality bovine embryos increases pregnancy success rate after embryo transfer.
Embryos of good, fair and poor quality were collected from superovulated cows and subjected to zona cutting (ZC) treatment using a needle under either an inverted microscope or a stereomicroscope. One (single transfer) or 2 (twin transfer) embryos with or without prior ZC treatment were transferred nonsurgically to recipients. Without the ZC treatment, lower embryonic quality resulted in lower ...
