The effect of insemination/injection time on the results of IVF and ICSI.

BACKGROUND The aim of this study was to investigate whether a pre-incubation time between oocyte retrieval and insemination or injection had any effect on the success rate of IVF or intracytoplasmic sperm injection (ICSI). Based on previously published data, many laboratories retain a time interval of several hours between oocyte retrieval and insemination/injection. In our setting, inseminatio...

Bull Fertility and Its Relation with Density Gradient Selected Sperm

Background sperm selection is generally used to describe methods for separation of spermatozoa for in-vitro-assisted reproduction. Few studies reported relation in vivo fertility and semen parameters after selection of fertile spermatozoa; hence, our research attempt to assess different semen parameters after post-thaw (PT) or after selecting sperm sample (SSp), using density gradient separatio...
