Fifteen female rhesus monkeys (Macaca mulatto), ranging in age from 8 to 34 years, were studied for one year to characterize the endocrine and menstrual changes associated with menopause in this species. Five monkeys were premenopausal; these younger monkeys, ages 8–11 years, menstruated and showed cyclic ovarian activity during the 12–month study period, as evidenced by menses and periodic elevations of serum estradiol (E2) and luteinizing hormone (LH) concentrations. Four females, ages 24–26… 

Neuroendocrine rhythmicity in the Rhesus macaque and the effec ts of aging

Monitoring reproductive hormones longitudinally from aged female rhesus macaques found that elevated plasma FSH was a better predictive factor of menopause onset than age, and suggested that an aging-related change in FSH, inhibin B, and AMH secretion may be the first endocrine manifestations of the transition into peri-menopause.

Neuroendocrine Changes in the Aging Reproductive Axis of Female Rhesus Macaques (Macaca mulatta)1

Monitoring reproductive hormones longitudinally from aged female macaques found that elevated plasma FSH was a better predictive factor of menopause onset than age, and suggest that an age-related change in FSH, inhibin B, and AMH secretion may be the first endocrine manifestation of the transition into perimenopause, potentially having value in predicting the onset of the perimenopausal transition.

Characterization of the onset of menopause in the rhesus macaque.

The results of this study illustrate that the decline of ovarian function in female macaques during the third decade of life parallels the menstrual and hormonal events associated with the climacteric in women, and that menopause does occur in rhesus macaques.

Ovarian senescence in the rhesus monkey (Macaca mulatta).

This study supports the value of the rhesus monkey as a model for reproductive ageing because its ovary undergoes follicular reservoir depletion similar to that seen in humans.

Estrogen and Progesterone Metabolites and Follicle-Stimulating Hormone in the Aged Macaque Female1

The nonbreeding season was associated with the highest number of abnormal cycles, suggesting that onset of complete ovarian senescence in these study macaques was more likely to occur during that time (i.e., females were less likely to return to normal ovarian cycles the following breeding season and morelikely to exhibit permanent ovarian quiescence).

Menopause in Free-Ranging Rhesus Macaques: Estimated Incidence, Relation to Body Condition, and Adaptive Significance

It is concluded that the occurrence of menopause in rhesus females is parsimoniously explained by the general evolutionary theory of aging and that the invocation of a special adaptive explanation, such as the grandmother hypothesis or a variant thereof, is unnecessary.

Aged Black-and-Gold Howler Monkey Female (Alouatta caraya): A Sign of Reproductive Senescence?

The results show that the aging female in this wild population of black-and-gold howler monkey female shows signs of ovarian senescence, indicated by low, acyclic levels of progesterone metabolites.

Perimenopause and menopause: documenting life changes in aging female gorillas.

Preliminary analyses of follow-up data on 10 perimenopausal females indicated that subjects experienced age-related changes in reproductive function that mirrored those observed in aging human females including a female who transitioned from perimenopause to menopause.



Developmental changes in the luteinizing hormone secretory pattern in peripubertal female rhesus monkeys: comparisons between gonadally intact and ovariectomized animals.

Developmental changes in LH release patterns were observed longitudinally in female rhesus monkeys at 10-65 months of age. The average ages of menarche and first ovulation in this experiment (n = 14)

Menstrual cycle characteristics of seasonally breeding rhesus monkeys.

The results suggest that during the seasonally delimited period of ovulation, females exhibit a range in the quality and quantity of ovulations which may be predicted by certain idiosyncratic physical and behavioral traits.

Seasonal variation in reproductive hormones of rhesus monkeys: anovulatory and short luteal phase menstrual cycles.

Results suggest that insufficient estrogen is secreted to evoke surges of gonadotropins in anovulatory cycles in rhesus monkeys, and that lengths of menstrual cycles were more irregular during the summer than during the winter months.

Seasonal effects on ovarian folliculogenesis in rhesus monkeys.

Investigation of the effect of season on development of the dominant follicle (DF) and upon levels of serum gonadotropins and sex steroids in animals maintained in a controlled environment found development appeared to be delayed in the early follicular phase during the summer months in those rhesus monkeys that had ovulatory menstrual cycles.

Endocrine control of the seasonal occurrence of ovulation in rhesus monkeys housed outdoors.

Low basal levels of gonadotropin secretion during the seasonal anovulatory period may result from diminished GnRH secretion or from an alteration in pituitary sensitivity to GnRH stimulation, and suggests that the timing of ovulations and associated changes in the neuroendocrine system controlling gonadotropic secretion may be mediated by an environmental variable.

The menopausal transition: analysis of LH, FSH, estradiol, and progesterone concentrations during menstrual cycles of older women.

The observation of elevated FSH concentrations and normal LH levels in perimenopausal women emphasizes the complexity of the hypothalamic-pituitary-ovarian regulatory system and suggests that LH and FSH are modulated independently at the level of the pituitary.

Hormonal characteristics of the human menstrual cycle throughout reproductive life.

The characterization of the menstrual history of the normal woman in terms of the hormonal changes that occur is permitted and provides a basis for the definition of several disorders of follicular maturation.

Developmental changes in the positive feedback effect of estrogen on luteinizing hormone release in ovariectomized female rhesus monkeys.

The results are interpreted to mean that an increase in LH release starts at the onset of puberty and continues until the age of first ovulation, and that the levels of LHRH release during the pubertal period may determine the effectiveness of estrogen on the LH surge.

Reproductive Behavior in the Rhesus Monkey: Social and Endocrine Variables

Copulatory behavior in female rhesus monkeys is strongly influenced by cyclic hormonal variables, and it is revealed that females tend to conceive on the first ovulatory cycle of the season, and that the best predictor of the timing of ovulation in a particular female is reproductive outcome in the previous year.
