Plasma estradiol and progesterone levels were analysed by radioimmunoassay in adult female langur monkeys during summer months. Summer was characterized in monkeys with irregular and prolonged menstrual cycles. In anovulatory cycles a reduction of estradiol and progesterone levels was observed as compared to ovulatory cycles.
