Contents The objectives of this work were to evaluate whether the sperm penetration speed
is correlated to the in vitro fertility and whether adapting the gamete co‐incubation length to …

It was previously demonstrated that the kinetics of early cleavage could be used to
discriminate between bovine bulls with high and low field fertility (Ward F et al. 2001 Mol …

Contents The objective of these experiments was to study bovine in vitro fertilization (IVF)
conditions for blastocyst production using non‐sexed sperm (Experiment 1) and sexed …

The objective of the present study was to evaluate the effect of various methods of sperm
selection and various sperm–oocyte co-incubation times on in vitro fertilization (IVF) of zebu …

The between bulls variation in in vitro fertility and the shift of sex ratio towards male embryos
are two problems affecting the in vitro production (IVP) of bovine embryos. Our objective was …

This study was conducted to examine if differences in bulls and sperm concentrations affect
fertilization in-vitro, with an overall objective of developing an in-vitro test to determine …

The present study consisted of two experiments. In the first one, ejaculates from four boars
were used to compare in vitro penetration (IVP) rates of fresh and vitrified swine oocytes by …

The objectives of this study were to evaluate the effect of sperm dose and sire on the
fertilization rate, cleavage rate and blastocyst yield following insemination in vitro, to …

Contents The objective of the present study was to determine whether sperm incubation
prior to oocyte insemination in vitro affects the sex ratio of resulting blastocyst. Cumulus …

In this study, a short coincubation time of 10min was used to determine the effect of different
sperm: oocyte ratios during in vitro fertilization (IVF), and different periods of post …
