the relation between the position and length of uterus and pregnancy rate in ivf and embryo transfer treatment cycles
background: embryo transfer has received little clinical attention and has been the most inefficient step in in-vitro fertilization (ivf). recent reports have suggested that an awareness of the position and length of the uterus during embryo transfer might be helpful in improving pregnancy rate. objectives: the main objective of the present study was to determine the relation between the length...
متن کاملElevated Progesterone Levels on the Day of Oocyte Maturation May Affect Top Quality Embryo IVF Cycles
In contrast to the impact of elevated progesterone on endometrial receptivity, the data on whether increased progesterone levels affects the quality of embryos is still limited. This study retrospectively enrolled 4,236 fresh in vitro fertilization (IVF) cycles and sought to determine whether increased progesterone is associated with adverse outcomes with regard to top quality embryos (TQE). Th...
متن کاملEstablishment of comparative performance criteria for IVF centers: correlation of live birth rates in autologous and donor oocyte IVF cycles
BACKGROUND To assess whether an objective performance criterion for in vitro fertilization (IVF) centers can be established. METHODS A retrospective analysis of 2011 National ART Surveillance System data for 451 U.S. IVF centers, 137 of which were included in the analysis since they performed >20 fresh embryo transfers per age group and >20 fresh oocyte donor transfers. The analysis of autolo...
متن کاملThe Effect of Four Different Gonadotropin Protocols on Oocyte and Embryo Quality and Pregnancy Outcomes in IVF/ICSI Cycles; A Randomized Controlled Trial
Background: Despite the large number of papers published on the efficiency of different exogenous gonadotropins, no confirmed protocol exists. Therefore, the aim of the present study was to compare the efficacy of 4 exogenous gonadotropins in IVF/ICSI cycles.Methods: This study, performed from January 2014 to May 2014, recruited 160 women referred to Ghadir Mother and Child Hospital and Dena Ho...
متن کاملObscure effect of aneuploidy on embryo morphology.
In this issue, Fragouli et al. report the results obtainedbyexamining a total of 1213 embryos by combining comprehensive chromosome analysis with a systematic assessment of embryo morphology. At the cleavage stage, chromosome abnormalities were common even amongst embryos assigned the best morphological scores, indicating that aneuploidy has little effect on microscopic appearance during the fi...
