In birds, several sperm typically enter the germinal disc, yet only one fuses with the female pronucleus. It is unclear whether supernumerary sperm play an essential role in the...

Type 2 receptors for vascular endothelial growth factor are believed to be involved in the pathophysiology of ovarian hyperstimulation syndrome (OHSS). The objective of this study was to examine the preventive effects of cabergoline on OHSS and its complications. The study is a non randomized clinical trial conducted in 2006-2008 on 75 patients, which were at risk of OHSS and underwent assisted...

Background Transfer of micro-Injected oocytes into fallopian tubes is an alternative procedure for IVF-ET with a similar success rate. This could be either done immediately after ovum pick-up microinjected oocytes intrafallopian transfer (MIFT) or after a time interval zygote intrafallopian transfer (ZIFT). This study was designed to compare the outcomes of the two procedures. MaterialsAndMetho...
