Three experiments were conducted to evaluate the effect of different macromolecule
components (egg yolk, skim milk, and BSA) in a widely employed extender for …

In this study, we evaluated the effects of glutathione (l‐γ‐glutamyl‐l‐cysteinylglycine; GSH)
supplementation of the freezing extender on semen parameters during the cooling (2 hours …

The extent of cellular damage was investigated after freeze–thawing of the European catfish
testicular sperm with various cryoprotectants. The best protection was given by …

The objective of this study was to evaluate the effects of thawing and processing
temperatures on post-thaw sperm viability, occurrence of osmotic shock and sperm …

The main aim of the present study was to investigate the effect of sperm freezing medium
dilution ratio (1: 1, 1: 2, and 1: 5v/v), two cryoprotectants: dimethyl sulphoxide (Me2SO) and …

Cryopreservation induces extensive biophysical and biochemical changes in the sperm. In
the present study, we used flow cytometry to assess the capacitation-like status of frozen …

The effects of extender composition and equilibration time on fertilizing ability of
cryopreserved spermatozoa from rainbow trout, Oncorhynchus mykiss, were investigated. In …

There are still several obstacles to effective cryopreservation of trout spermatozoa as seen
by the large variability of fertility rates obtained with frozen–thawed spermatozoa. We …

The success of semen cryopreservation is influenced by several factors, such as freezing
curves and cryoprotectants. These two factors are of special interest once they may lead to …

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