Sperm cryopreservation is one of the most important procedures in the development of
biotechnologies for assisted reproduction. In some farm animals, the use of cryopreserved …

Contents Finding a laboratory test reliable enough to predict the potential fertility of a given
semen sample or a given sire for artificial insemination (AI) is still considered utopian, as …

Cryopreservation induces many changes in sperm cells, including membrane disorders and
cell death. We tested the hypothesis that apoptosis, a form of programmed cell death, can …

Contents Flow cytometry has become an important technique in sperm evaluation and is
increasingly used both for routine assessment and for research in veterinary science. We …

The study was to focus on the relationship between wave motion (mass sperm motility,
measured by a mass sperm motility score, manually assessed by artificial insemination (AI) …

Flow cytometry is now a recognized methodology within animal spermatology, and has
moved from being a research tool to become routine in the assessment of animal semen …

Contents Bull fertility is influenced by numerous factors. Although 20–40% of bulls in an
unselected population may have reduced fertility, few are completely sterile. Breeding …

The accurate prediction of bull fertility is of major economic importance in the dairy breeding
industry. Sperm fertilizing potential is determined by their ability to reach the oocyte …

The process of cryopreservation impairs sperm cell function, potentially leading to a
reduction in fertility. The objectives of the present study were to evaluate the effects that …

Cervical artificial insemination (AI) in sheep with fresh semen yields a much higher
pregnancy rate than when frozen-thawed semen is used, and consequently frozen semen is …
