Male rats were tested for mating behaviour after being fitted with a plastic collar which prevented oral genital grooming which normally occurs after intromission and ejaculations. Comparison with tests involving a short control collar revealed that prevention of genital grooming did not after quantitative or temporal aspects of general mating activity. When genital grooming was prevented, brief erections of the glans penis were usually observed after intromissions. Following withdrawal of the male from the female after ejaculations, there occurred erections, rapid dorsal flips, and extended dorsal flips of the penis which resembled responses observed in spinal animals in a previous study of sexual reflexes. Results suggest that when genital grooming is allowed, penile erections and movements are apparently suppressed.
