The prediction of sperm fertilizing ability has great economic importance for breeding herds
when artificial insemination is used. Classical methods of semen evaluation generally …

This presentation deals with assays based on in vitro fertilization (IVF) and related
techniques such as zona pellucida (ZP) binding assays and oocyte penetration tests. These …

The aims of this work were to adapt the hypoosmotic swelling test (HOST) to boar
spermatozoa and to compare this method with other tests which evaluate the integrity of the …

Our ability to screen the structural and functional integrity of the spermatozoon in vitro has
increased markedly over the past decades, but our capacity to estimate the fertility of a …

Contents Recent advances in new technologies to produce cloned and genetically modified
pigs involve manipulating oocytes and/or embryos in vitro. Although a great deal of progress …

A series of integrated, effective techniques is required to produce pig embryos from follicular
oocytes in vitro. The failure to form a male pronucleus and polyspermy have been serious …

The “predictors of useable semen” used in most commercial AI centers provide a very
conservative estimate of the relative fertility of individual boars. Furthermore, the relatively …

The present study was designed to evaluate the brilliant cresyl blue (BCB) test as a means
of selection of immature pig oocytes to improve the performance of the homologous in vitro …

Contents Estimating the fertility of a semen sample or of the male from where it has been
collected by simple assessment of in vitro sperm characteristics is still difficult, owing to the …

A field trial was conducted to compare the fertility predicting capacity of different sperm
assays applying classical semen analysis, sperm function and the homologous in vitro …
