Number of embryos transferred after in vitro fertilization and good perinatal outcome.
OBJECTIVE To assess the association between number of embryos transferred and a measure of assisted reproductive technology success that emphasizes good perinatal outcome. METHODS We analyzed assisted reproductive technology cycles initiated in 2011 that progressed to fresh embryo transfer among women using autologous oocytes and reported to the U.S. National Assisted Reproductive Technology ...

Guidelines on number of embryos transferred.
Based on American Society for Reproductive Medicine (ASRM) and Society for Assisted Reproductive Technology data available in 2007, ASRM's guidelines for the number of embryos to be transferred in in vitro fertilization cycles have been further refined in continuing efforts to reduce the number of higher-order multiple pregnancies. This version replaces the document of the same name that was pu...
متن کاملFollicle flushing in monofollicular in vitro fertilization almost doubles the number of transferable embryos
Follicle flushing has been proved to be ineffective in polyfollicular in vitro fertilization. To analyze the effect of flushing in monofollicular in vitro fertilization we aspirated and then flushed the follicles in 164 cycles. Total oocyte yield/aspiration was 44.5% in the aspirate, 20.7% in the 1(st) flush, 10.4% in the 2(nd) flush and 4.3% in the 3(rd) flush. By flushing, the total oocyte...
متن کاملEffect of Fresh and Frozen Semen on in vitro Fertilization and Subsequent Development of Goat Embryos
This study was undertaken to compare the efficiency of fresh and frozen-thawed buck semen on in vitro fertilization (IVF) of goat oocytes. Cumulus oocytes complexes (COCs) were collected by aspiration of 2-6 mm diameter follicles, which were obtained from slaughterhouse. Upon grading, only normal quality COCs were maturated in TCM-199 for 48 hours. The percentage of COCs reached to the M-II sta...
