Abstract: The relationship between the Content of estrogen and the activity of luteinizing hormone(LH )and chorionic gonadotropin(CG)was presented in two pregnant and two nonpregnant snub-nosed monkeys (Rhinopithecus roxeltanae) tested with human estrogen and LH/CG diagnostic reagents in ragular time．The results demonstrated the two reagents used in human had a certain cross-reaction in snub-nosed monkeys，and they basically represented the follicle forming,ovulating and luteinizing time in these monkeys．The estrogen peak range was in 29ug/ml to 532.5ml．Several days later after the hormone peak，menses appeared and lasted one to four days．The interval between peaks is 20-30 days.Estrogen increased in a month after pregnant and was a double or more higher than the normal.It disappeared with LH/CG half a month before parturition in their urine，and reappeared after parturition．The LH/CG peak is 2500IU/750IU/ml. LH/CG increased in early pregnancy,and was a double or more than nomal，but decreased in a month．Similar with estrogen,they disappeared half a month before parturition，and reappeared after that.
