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 …

Cryopreservation is the most efficient method for long-term preservation of mammalian
sperm. However, freeze-thawing procedures may strongly impair the sperm function and …

Artificial insemination with frozen‐thawed semen in pigs is not a routine technique; its use is
restricted to specific cases, such as preservation of valuable genetic material (germplasm …

Spermatozoa interact with their immediate environment and this contact remodels the sperm
surface in preparation for fertilisation. These fundamental membrane changes will be …

Contents While sperm cryopreservation is the best technology to store boar semen for long‐
term periods, only 1% of all artificial inseminations (AI) conducted worldwide are made using …

Sperm cells can be damaged during the semen cryopreservation process, decreasing their
fertilizing ability. Physical damage and oxidative stress may occur during the freeze–thawing …

Introduction Freezability is the ability of sperm to maintain its vitality and quality from various
stress during the cryopreservation process, which is very important for the success of …

Variation in boar sperm freezability (ie capacity to withstand cryopreservation) between
ejaculates is a limitation largely reported in the literature. Prediction of sperm freezability and …

Contents One of the limits to practical use of frozen boar sperm involves the lowered fertility
when used for artificial insemination. Years of studies have shown that 5–6 billion sperm …

The main aim of the present study was to determine whether differences in the amounts of
free cysteine residues in sperm nucleoproteins, which are a direct marker of the integrity of …
