The following parameters of the Taiwan monkey,Macaca cyclopis, are presented and compared with other species ofMacaca: the menstrual cycle, sexual skin and vaginal desquamation changes during the menstrual cycle, time of ovulation, gestation period, breeding season, body weight of the newborn, age and body weight at menarche, body weight at first conception, spermatozoa count in the ejaculate, and the body weight at sexual maturity of the male.The many similarities in reproductive biology ofMacaca cyclopis,the rhesus monkey (Macaca mulatta), and the cynomolgus monkey (Macaca irus) include sexual skin and vaginal desquamation changes during the menstrual cycle, time of ovulation, gestation period, and placental sign. Body weight ofM. cyclopisis lower thanM. mulattaat birth, at menarche and at the first conception in females and at sexual maturation in males, is heavier thanM. irusat birth and is not different fromM. radiataat birth. No difference in menstrual cycle ofM. cyclopiswas observed in animals housed in air-conditioned rooms compared to those housed in nonair-conditioned rooms. Summer amenorrhea was not observed inM. cyclopisbut a high incidence of low vaginal desquamation was noted to occur in summer months. The mode of length of the menstrual cycle ofM. cyclopisis shorter thanM. mulattaand other species ofMacaca.The breeding season ofM. cyclopisin the wild extends from the end of September to January. In laboratory conditions their fertile period extends throughout the year.
