Comparative studies of reproductive characteristics were carried out on a colony of Macaca fascicularis and M. arctoides. Seasonal differences were not significant between species, and conceptions occurred throughout the year. The occurrence of short cycles ('luteal phase defect') was found in 2.9% of all M. fascicularis cycles and 1.5% of all M. arctoides cycles. Long cycles (40-50 days) were found in 4.0% of all M. fascicularis cycles and 3.5% of all M. arctoides cycles. Gestation lengths… Expand
[Menstrual cycle lengths and the estimated time of ovulation in the cynomolgus monkey (Macaca fascicularis)].
A marked increase of serum follicle stimulating hormone (FSH) concentration was observed from 8 to 15 days after menstruation, and a cycle length can not be predicted on the basis of the length of the previous menstrual cycle. Expand
Characteristics of the menstrual cycle in nonhuman primates. IV. Timed mating in Macaca nemestrina
The events of the perineal swelling cycle in Macaca nemestrina have been correlated with the optimal time for conception, a value comparable with similar calculations for other macaque species. Expand
Reproduction and social rank in female stumptail Macaques (Macaca arctoides)
No systematic seasonal fluctuations were found in the onset of sexual maturity, in ovarian cycle lengths, in copulation frequencies, and in distribution of births in female stumptail macaques. Expand
Monitoring Ovulation and Implantation in the Cynomolgus Macaque (Macaca fascicularis) Through Evaluations of Urinary Estrone Conjugates and Progesterone Metabolites: A Technique for the Routine Evaluation of Reproductive Parameters
Investigations were undertaken to determine the applicability of recently reported specific radioimmunoassays for urinary estrone conjugates and progesterone metabolites for monitoring ovarianExpand
Female menstrual cyclicity and sexual behavior in stumptail Macaques (Macaca arctoides)
The sexual behavior and female reproductive cycles of a captive group of stumptail macaques were monitored during a 12-month period and data show marked increases in copulations during the periovulatory phase. Expand
A review of sexual initiating behavior by male and female cynomolgus monkeys and some species comparisons
It is concluded that estradiol in the female and testosterone in the male increase the sexual motivation of both the treated and the untreated partner. Expand
Male-Induced Sociosexual Behavior by Vaginal Secretions in Macaca arctoides
The results suggest that vaginal secretions are among the cues that male Macaca arctoides use to acknowledge the reproductive status of females in the absence of visual signals, and that Exploratory behavior of males correlates significantly with their social rank. Expand
The Mammary Glands of Macaques
The normal biology and physiology of the mammary gland in macaques is described, including the typical histologic appearance across the life span (development, reproductive maturity, lactation, and senescence), as well as systemic and local hormonal regulators of mammary glands proliferation, differentiation, and function.

Sexual swellings in wild white-handed gibbon females (Hylobates lar) indicate the probability of ovulation
This work studied the temporal patterns of sexual swellings, timing of ovulation and female reproductive status in wild white-handed gibbons at Khao Yai National Park, Thailand, where this species has a variable social organization. Expand
Reproductive Parameters of Captive Grey-Cheeked Mangabeys
This paper reports reproductive parameters for 9 female grey-cheeked mangabeys kept in a captive colony over a 17-year period. Birth seasonality has shown a consistent trend towards an autumn peak.Expand
