The use of morphokinetics as a predictor of embryo implantation.
BACKGROUND Time-lapse observation presents an opportunity for optimizing embryo selection based on morphological grading as well as providing novel kinetic parameters, which may further improve accurate selection of viable embryos. The objective of this retrospective study was to identify the morphokinetic parameters specific to embryos that were capable of implanting. In order to compare a lar...
متن کاملEmbryo selection in IVF.
To optimize success rates of IVF, selection of the most viable embryo(s) for transfer has always been essential, as embryos that are cryopreserved are thought to have a reduced chance of implanting after thawing. Recent developments challenge this concept. Evidence is accumulating that all embryos can now be cryopreserved and transferred in subsequent cycles without impairing pregnancy rates or...
متن کاملAttitudes towards embryo donation among infertile couples with frozen embryos.
STUDY QUESTION What are the attitudes towards different aspects of embryo donation among Swedish infertile couples who have surplus cryopreserved embryos? SUMMARY ANSWER Nearly three-quarters of infertile couples with surplus embryos were in favour of embryo donation. A majority of respondents were also in favour of embryos being donated for research. WHAT IS KNOWN ALREADY Currently, embryo...
متن کاملI-9: Embryo Assessment and Selection
Over the years it has been an important goal to optimize the treatment of subfertility in order to obtain a better pregnancy rate and baby-take-home rate, usually combined with the goal of decreasing the rate of multiplet pregnancies. This implies optimizing the development of embryos through improved in vitro culture methods. And it also implies optimizing the methods of selection of embryos f...
متن کاملSelection for rapid embryo development correlates with embryo exposure to maternal androgens among passerine birds.
Greater offspring predation favors evolution of faster development among species. We hypothesized that greater offspring predation exerts selection on mothers to increase levels of anabolic androgens in egg yolks to achieve faster development. Here, we tested whether (1) concentrations of yolk androgens in passerine species were associated with offspring predation and (2) embryo and nestling de...
