Abstract

The time spent by the female rhesus monkey in grooming the male fluctuates rhythmically and reaches a minimum at mid-cycle. At this time the male's grooming activity reaches a maximum. The rhythmic changes in male mounting behavior, together with the males' and females' grooming cycles, are abolished by ovariectomy and have a hormonal basis.
