  • Grape Seed Procyanidin Extract (GSPE) Improves Goat Sperm Quality When Preserved at 4 °C. [Journal Article]
    Animals (Basel) 2019; 9(10)Wen F, Li Y, … Hu J
  • Grape seed procyanidin extract (GSPE) has been shown to possess antioxidative effects. This experiment was designed to study the effect of GSPE during the liquid storage of goat semen. Semen samples were collected from six sexually mature goats. The samples were treated with different concentrations of GSPE (10, 30, 50, and 70 mg/L) in basic diluent and stored at 4 °C for 120 h; samples without G…
  • Egg yolk-free cryopreservation of bull semen. [Journal Article]
    PLoS One 2019; 14(10):e0223977Anzar M, Rajapaksha K, Boswall L
  • Egg yolk is a common ingredient of mammalian semen extender to protect sperm against initial cold shock. However, egg yolk has biosecurity risks. Our main objectives were to cryopreserve bull semen without egg yolk using exogenous cholesterol and to study the protective role of glycerol in egg yolk-free semen extender. Other objectives were to compare protein profiles and in vitro fertilization p…
  • Semen preparation techniques for intrauterine insemination. [Review]
    Cochrane Database Syst Rev 2019; 10:CD004507Boomsma CM, Cohlen BJ, Farquhar C
  • CONCLUSIONS: There is insufficient evidence to recommend any specific semen preparation technique: swim-up versus gradient versus wash and centrifugation technique. No studies reported on live birth rates. Considering the quality of evidence (very low), we are uncertain whether there is a difference in clinical pregnancy rates, ongoing pregnancy rates, multiple pregnancy rates or miscarriage rates per couple) between the three sperm preparation techniques. Further randomised trials are warranted that report live birth data.
