Mammalian sperm preservation in extenders containing egg yolk (EY) and/or milk has been
used for over half a century. However, the mechanism by which EY or milk protects sperm …

This review describes the use of modern reproductive biotechnologies or assisted
reproductive techniques (ART) including artificial insemination, embryo transfer/sexing, in …

TRIS-glucose or skim milk extenders are most commonly used for cryopreserving goat
sperm. The aim of this study was to compare the ability of two extenders based on TRIS and …

In the present study, computer‐automated sperm head morphometry of epididymal samples
was used to determine if sperm head area and shape are useful measurements for …

The aim of this study was to evaluate the effect of semen collection method (artificial vagina
compared to electroejaculation), season in which the semen was collected (breeding …

This study compares the effectiveness of the ultra-rapid and conventional freezing of sperm
from captive bovids, giraffids, cervids, ursids, a cercopithecid, a delphinid and a …

The use of glycerol for boar semen cryopreservation results in low fertility, possibly due to
toxicity. This has led to recommend the use of solutions with less than 4% glycerol …

Seminal quality parameters were used to evaluate the effect of freeze–thawing procedure on
goat sperm characteristics, and to relate possible changes in sperm parameters to …

The relation among inbreeding, heterozygosity, and fitness has been studied primarily
among outbred populations, and little is known about these phenomena in endangered …

Cryopreservation of spermatozoa from endangered species is a valuable tool for genetic
management. Previous studies showed the feasibility of cryopreservation of spermatozoa …
