With the term “assisted reproduction technologies” in modern cattle farming, one could imply
the collection of techniques that aim at the optimal use of bovine gametes to produce …

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 …

Reactive oxygen species (ROS) are implicated in all aspects of cellular functions. While the
importance of ROS as signalling molecules is well described, ROS are also associated with …

To present a coherent and meaningful survey of scientific research endeavour in an area
that has expanded as fast as physiology and biochemistry of reproduction in the male is no …

The effect of low temperatures on the ultrastructure of the plasma membrane of bull and boar
spermatozoa was investigated. Cold-induced changes in the organization of sperm plasma …

Motion characteristics, plasma membrane integrity, and acrosome morphology of buffalo
spermatozoa after different stages of cryopreservation (ie, dilution, cooling to 4° C …

Flow cytometry was used to compare the functional status of fluorescently stained sperm
organelles from 12 Holstein bulls after storage for 24 h at 5° C and after cryopreservation …

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

Many theories have been postulated concerning the possible effects of cryopreservation on
spermatozoa, including suggestions the freeze–thawing process produces membranes that …

Demand for alternative of egg yolk in freezing extenders have increased in recent years due
to variability in egg yolk composition, risk of microbial contamination and presence of steroid …
