The extender based Prikry forcing notion is being generalized to supercompact extenders.

Reactive oxygen species (ROS) generation, induced by the cryopreservation process, can be responsible for mammalian sperm damage. Curcumin is known as an effective antioxidant against oxidative stress. The aim of this study was to evaluate the effects of curcumin on sperm count, motility and viability, semen total antioxidant capacity and DNA integrity of rat spermatozoa during semen freeze-tha...

The aims were to evaluate the suitability of a non-commercial TRIS-lecithin (LC) extender and the effect of different concentrations of catalase (CAT) on motility, capacitation status (Chlortetracycline-assay) and zona pellucida (ZP) binding capacity of canine spermatozoa stored at +5 degrees C for 4 days. The sperm-rich fractions of the ejaculates of four stud dogs were divided into four aliqu...

The objective of this study was to determine the effects of thawing groups of 2, 5, 10, 15, or 20 .5-ml French straws on post-thaw spermatozoal viability. Thermostatically controlled and nonthermostatically controlled thawing baths were compared. Using a split-plot design, semen from 10 bulls was extended in egg yolk citrate, frozen, and then thawed (in the respective groups) at 36 degrees C in...

The study evaluated the effect of two animal protein-free extenders on ram semen cryopreservation tropical hair breeds. ejaculates were collected from 8 rams (4 Blackbelly and 4 Pelibuey), which mixed (pooled) by breed, diluted cryopreserved in three different extenders: Animal protein [Tris egg yolk (Triladyl®)], AndroMed® (lecithin soy bean) OPTIXcell® (liposome). Sperm analyses total (TM) pr...

This experiment wascarried out to explore the effect of use of combinations of permeating cryoprotectant and non permeating cryoprotectant on thequality of frozen-thawed Beluga (Huso huso) spermas compared to the use of permeating cryoprotectant as a control. For this work methanol (MeOH) and dimethyl sulfoxide (DMSO)are used aspermeatingcryoprotectantsand bovine serum albuminas a non permeatin...
