An improved mechanical technique for assisted hatching.
BACKGROUND Varied clinical outcomes of assisted hatching (AH) have been reported. We attempt to investigate whether the size of the zona opening created by AH is adequate for blastocyst hatching, and, if not, set up a new method to improve it. METHODS A new AH technique, long zona dissection (LZD), was established, and experiments were performed to compare the effects of different sizes of zo...
متن کاملAssisted Hatching for In Vitro Fertilization-Embryo Transfer: An Update
Assisted Hatching (AH) is a technique performed after In Vitro Fertilization (IVF) and involves the artificial thinning or opening of the Zona Pellucida (ZP) prior to Embryo Transfer (ET) as an attempt to improve the probability of embryo implantation. AH can be performed by embryologists via mechanical, chemical, or laser-assisted means. A few studies suggest that a larger size of ZP opening/t...
متن کاملSpontaneous Mesenchymal to Epithelial Like Tissue Transition (MET) in a Long Term Human Skin Culture
In an attempt to isolate multipotent stem cells from foreskin in a long-term culture, we encountered an interesting phenomenon which was the conversion of the fibroblast dominant condition to epithelial-like tissue formation. However, the basic mechanism(s) which may be involved in this conversion is not clear. This study was designed to evaluate the cells protein secretion activity and examine...
متن کاملAssisted hatching of human embryos: a systematic review and meta-analysis of randomized controlled trials.
BACKGROUND Assisted hatching (AH) is a manipulation of zona pellucida aiming to facilitate embryo implantation. METHODS Systematic review and meta-analysis of medical literature was used to evaluate the effect of AH on assisted reproduction outcomes: clinical pregnancy, live birth, multiple pregnancy and miscarriage. Additional analysis was performed in these subgroups: (i) fresh embryos tran...
متن کاملP-156: Survey of In Vitro Effect of Resveratrol on Apoptosis of Human Endometrial Epithelial Cells
Background: In apoptosis is physiological cell death which eliminates injured and old cells. Any disruption in apoptosis, leads to disease. Resveratrol is a natural polyphenol with estrogen-like, antioxidant and antiinflammatory properties; also it showed cell prolifratory and inhibitory effect. The aim of present study was to determine resveratrol effect on apoptosis of human endometrial epith...
