I-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 کاملP-126: Duration of Exposure to Polyvinylpyrrolidone (PVP): The Effects on Fertilization Rate and Embryo Development
Background: Recently, it has been found that exposure of sperm to PVP may cause submicroscopic changes in sperm structure and the sperm nucleus. The PVPinduced nuclear damage may have been due to breakdown of sperm membranes. Consequently, it is probable that exposure of sperm to PVP may impair embryo development. There are apparently no detailed reports regarding the specific effects of PVP on...
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...
متن کاملCritical reappraisal of embryo quality as a predictive parameter for pregnancy outcome: a pilot study
AIM OF THE STUDY Pilot study to analyse the efficacy and embryo morphology using a new human embryo culture medium (GM501) versus the conventional used medium (ISM1). METHODS Over a four-month period, all patients at the Leuven Institute of Fertility and Embryology (LIFE) were -randomly allocated to have their embryos cultured in either the standard sequential culture medium ISM1 (control) or...
متن کاملEffect of diabetes mellitus on quality and quantity pregnant rat in Pre-implantation embryo development
Introduction: Women with poorly controlled insulin-dependent diabetes mellitus (IDDM) have a much higher incidence of early pregnancy complications, these include spontaneous miscarriages, early growth delay, and congenital malformations. Most of the investigations have been devoted to the early post implantation and organogenesis period of pregnancy. In this research we studied the hyperglycem...
