Electroejaculation of 17 rhesus monkeys was performed at intervals during a 15-month period using both penile and rectal probe stimulation. The semen quality was compared for the two stimulation methods. Both methods were effective in approximately 90% of attempts, and there was no difference in fertilizing capacity of the sperm. A seasonal difference in semen quality was detected, and samples recovered by penile stimulation showed higher sperm count.
