Cholesterol-loaded cyclodextrins added to fresh bull ejaculates improve sperm cryosurvival.
Damage occurring to spermatozoa during cryopreservation results in a loss of motile cells and cells that are functionally normal, compared with fresh sperm samples. Treating bull sperm with cholesterol-loaded cyclodextrins (CLC) before cryopreservation results in increased sperm cryosurvival. However, in previous studies, CLC were always added to sperm samples that had been highly diluted. The ...
متن کاملFactors influencing boar sperm cryosurvival.
Optimal sperm cryopreservation is a prerequisite for the sustainable commercial application of frozen-thawed boar semen for AI. Three experiments were performed to identify factors influencing variability of postthaw sperm survival among 464 boar ejaculates. Sperm-rich ejaculate fractions were cryopre-served using a standard freezing-thawing procedure for 0.5-mL plastic straws and computer-cont...
متن کاملاثرات آنتی اکسیدان ملاتونین بر پارامتر های حرکتی، میزان گونه های فعال اکسیژن (ROS) و مالون دی آلدهید (MDA) در اسپرم منجمد شده انسانی
Abstract Background: Oxidative damage to sperm resulting from reactive oxygen radicals and lipid peroxidation generated by the cellular components of semen during sperm freezing is possibly one of the main causes of the decline in motility during storage. The aim of this study was to evaluate the antioxidant effect of melatonin in different doses on oxidative stress and motility of cryo-pre...
متن کاملFreezing Canine Semen
There are many reasons for freezing canine semen. Perhaps the most important reason is to preserve and insure the breeding potential of a dog against loss, death or infertility. This provides for the stud dog to sire puppies when he is no longer able to do so. Freezing semen also allows for the transport of genetic material both within and between countries. This obviously increases the marketi...
متن کاملEffect of antioxidant on sperm freezing
A major cause of male infertility, which includes 50 causes of infertility, is oxidative stress. The aerobic respiration in the sperm cell is associated with the production of reactive oxygen species (ROS). Some reactions such as sperm capacitation and acrosome reactions require moderate levels of ROS. However, when the amount of ROS production surpasses the natural antioxidant defense of the ...
