A method for electroejaculation of the macaque was successful in 8 of 11 subjects. Repeated electroejaculation at 2–3 day intervals did not cause a refractory state. Coagulation occurred almost immediately on ejaculation. Liquefaction began shortly thereafter, but was incomplete. Sperm concentration in the liquefied portion of the ejaculate ranged between 93 and 807 million/cc. Tail length was approximately 70 μ, as compared with 50 μ, in human material. Electroejaculation is suggested as a practical means of obtaining monkey semen.
