Sperm cryopreservation represents a powerful tool for livestock breeding. Several efforts
have been made to improve the efficiency of sperm cryopreservation in different ruminant …

Cryopreservation of spermatozoa is becoming more important because of new clinical
requirements and current clinical practice. Despite the success of sperm cryopreservation …

The genetic improvement of agriculturally important species and disease control are of
fundamental importance to the success of a sustainable agri-food industry. In this sense …

Cryopreservation extends the availability of sperm for fertilization; however, the fertilizing
potential of the frozen-thawed sperm is compromised because of alterations in the structure …

In the present study, we provide evidence for the production of reactive oxygen species
(ROS) during cryopreservation of bovine spermatozoa. Cooling and thawing of spermatozoa …

Spermatozoa are very specialized cells, dedicated to fertilization of the oocyte. The
attainment of this biological role is partly due to the fusogenic properties of the sperm …

DNA damage in the male germ line has been associated with poor semen quality, low
fertilization rates, impaired preimplantation development, increased abortion and an …

We previously showed that cryopreservation of bull spermatozoa in egg yolk Tris extender
(EYTG) significantly reduced the intracellular level of thiols. Other studies showed the …

OBJECTIVE: The manipulation of gametes and embryos in an in vitro environment when
performing assisted reproductive techniques (ART) carries the risk of exposure of these cells …

Although glutathione content in boar spermatozoa has been previously reported, the effect
of reduced glutathione (GSH) on semen parameters and the fertilizing ability of boar …
