Contents Motility is one of the most important characteristics associated with the fertilizing
ability of spermatozoa and is an expression of their viability and structural integrity …

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 objectives of this study were to compare different methods of evaluating sperm
plasmalemma and to determine their relationship with in vitro fertilization rate. A single batch …

The performance of frozen-thawed spermatozoa from 10 Holstein bulls in a range of in vitro
diagnostic tests and the relationship with adjusted in vivo fertility data was determined. The …

Background There is speculation that beef bull semen quality is inferior to that of dairy bulls
although few scientific studies are available in the literature. The aim of this study was to …

Cryopreservation imposes irreversible damage to sperm membranes, such as swelling and
disruption of plasma and acrosome membranes, changes in membrane fluidity, altered …

We investigated fluorometry to study sperm viability and flow cytometry to study sperm
chromatin structure. We also assessed sperm quality after thawing relative to field fertility …

The objectives of this study were:(1) to evaluate the effect of sire on the time from
insemination to first cleavage following insemination in vitro and the relationship of this …

Diagnosis of the fertility potential of a semen sample is essential for consistently high
reproductive efficiency. The use of subfertile or infertile semen can have devastating …

Within recent years, there has been growing interest in the prediction of bull fertility through
in vitro assessment of semen quality. A model for fertility prediction based on early …
