RETARDED EJACULATION Retarded ejaculation is defined as the man's ability to ejaculate only after what seems to him to be an ‘excessive’ time. It is usually reported when the man requires ½ an hour or more of vigorous coital thrusting. Interestingly, most of these men do not seem to have any difficulties with an erection but sometimes seem to hold them back. They are unable to trigger the ejaculatory reflex at the proper time.
