In this study, different combinations of 2-step, discontinuous gradient centrifugation were
used, consisting of three different combinations of isotonic Percoll (45/60, 60/75 and …

Repeatable methods for IVF have not been established in the horse, reflecting the failure of
standard capacitating media to induce changes required for fertilization capacity in equine …

Background The in vivo concentration of bicarbonate (HCO 3−), one of the essential sperm
capacitating effectors, varies greatly in the different environments sperm go through from …

Antioxidants may be useful for supplementing sperm extenders. We have tested
