Abstract
A successful technique for electroejaculation with nonmetallic electrodes cut from defibrillation pads is described. Twenty‐six adult male cynomolgus and eleven adult male rhesus macaques were electroejaculated while immobilized with chair restraint. From 123 attempted electroejaculations in both species of macaques, 119 semen specimens were obtained. The volume, concentration, % motility, and % normal forms of cynomolgus and rhesus macaque semen are presented. The use of nonmetallic electrodes provides a high quality ejaculate while minimizing the risks of adverse affects on valuable populations of macaques.
