The effects of four reagents on the activation and subsequent fertilization of equine oocytes,
and the development of these after intracytoplasmic sperm injection, were investigated …

The present study was conducted to determine if the efficiency of in vitro pig embryo
production could be improved by a reduction in the period of time that oocytes are exposed …

Three experiments were designed for the in vitro fertilization of in vivo matured oocytes
following different sperm treatments: In experiment I, spermatozoa (sperm rich fraction) were …

The objective of this study was to assess the development of porcine ova fertilized by

stage embryos in vitro involved study of 1924 oocytes in experiments designed to examine …

Intracytoplasmic sperm injection (ICSI) of a nonmotile cell into the ooplasm for assisted
fertilization is a highly specialized procedure for producing the next generation. The …

This study was designed to investigate the effect of sperm exposure time on the fertilization
rate and subsequent developmental capacity of bovine oocytes matured in vitro. Cumulus …

This study was designed 1) to determine the effectiveness of 2 in vitro maturation systems
