Seasonal Changes in Sperm Chromatin Condensation in Ram（Ovis aries）, Iberian Red Deer （Cervus elaphus hispanicus）, and Brown Bear（Ursus arctos）
SCSA season
2008/12/24
The effect of seasonality (temperate environment, Spain) on the chromatin status of ovine (Churra breed), Iberian red deer, and brown bear spermatozoa was studied. This work aims to improve genet...
Comparative Study of Four Different Sperm Washing Methods Using Apoptotic Markers in Ram Spermatozoa
Swim-up caspase activity annexin V
2008/12/24
The accurate measurement of semen fertilizing potential is of great importance in determining the acceptability of processed semen for breeding purposes. A good sperm preparation technique result...
Immunohistochemical Localization of Sperm-Preserving Proteins in the Ram Reproductive Tract
Seminal plasma proteins seminal vesicles cold shock ram spermatozoa
2008/12/24
Previously, we reported that the addition of seminal plasma proteins before cold-shock treatment prevents sperm membrane injury, and that 2 proteins of approximately 14 (P14) and 20 (P20) kDa,...
Immunocytochemical Localization and Biochemical Characterization of Two Seminal Plasma Proteins That Protect Ram Spermatozoa Against Cold Shock
Immunocytochemistry capacitation acrosome reaction
2008/12/23
We have already shown that seminal plasma proteins in the ram can repair cold-shock sperm membrane damage and that the addition of seminal plasma proteins before cold-shock treatment prevents sperm ...
Ram Sperm Selection by a Dextran/Swim-Up Procedure Increases Fertilization Rates Following Intrauterine Insemination in Superovulated Ewes
Sperm quality reproductive efficiency IUI
2008/12/22
The objective of this study was to compare the efficacy of 2 dextran/swim-up media to increase the sperm quality parameters and the maintenance of these parameters at 15°C and 30°C over 6 hours. A...
Cryopreservation of Ram Semen Facilitates Sperm DNA Damage: Relationship Between Sperm Andrological Parameters and the Sperm Chromatin Structure Assay
Artificial insemination semen quality motility chlortetracycline viability SCSA
2008/12/22
We hypothesized that cryopreservation and incubation in conditions that mimic the female genital tract following insemination increases the susceptibility of ram sperm DNA to denaturation. Ram spe...
