BACKGROUND To test whether poor quality day-3 embryos can undergo successful blastulation and implantation. METHODS A prospective cohort study was conducted. Whether or not a good quality embryo was transferred on day-3, poor quality (rejected) embryos were further cultured and followed. The clinical outcome of each embryo was assessed. RESULTS A total of 694 rejected embryos (from 205 pati...

the major objective of seedless grape breeding program is production of grapes with high quality. breeding of seedless grapes is difficult because the embryos are aborted after fertilization. embryo rescue technique is utilized to obtain plants from crosses between seedless cultivars. in the present study, the effect of paternal genotypes and different iaa concentrations in presence of ba appli...

background: gnrh agonist and antagonist were developed to control the premature release of lh surge. there is some difference between two protocols. objective: we compared the outcome of frozen-thawed embryo transfer in infertile women who used gnrh agonist or antagonist protocol for previous coh cycle and evaluation of any adverse effect of gnrh antagonist on oocyte and embryo. materials and m...

Abstract Study question Is an AI model as good experienced embryologist? Summary answer Properly trained models can perform embryologists with respect to accuracy, improving in the same time decisiveness. What is known already There are many attempts solve embryo selection problem. One way determine specific features of and on this basis calculate final score. The non-algorithmic approach uses ...

Background: A prerequisite for successful embryo implantation is adequate preparation of receptive endometrium and the establishment and maintenance of a viable embryo. The success of implantation further relies upon a two-way dialogue between the embryo and uterus. However, molecular bases of these preimplantation and implantation processes in humans are not well known. Materials and Methods: ...

objective: in recent years, antibiotics have been used widely in the glob to prevent and treat bacterial diseases. they injected into eggs to eliminate pathogens and prevention of egg transmission of disease, but the adverse effects of drugs have always been a major concern. there is little information available about the safety of tetracycline drugs in the embryonated eggs of the birds. the ob...
