“…The tortuous blood vessels in the gastrocolic omentum resembled the spiral arteries in the human and simian endometrium 2 . The morphological structures in the present case were similar to those of reported endometriosis in rhesus monkeys [3][4][5] , and this case was, therefore, diagnosed as endometriosis.…”

Spontaneous endometriosis was found in a 15-year-old female rhesus monkey. Macroscopically, there was thickening of the intestinal wall, mesenterium, and the gastrocolic omentum. Sporadic nodules were noted in the serosa of the jejunum and ileum. Histopathologically, a large number of glandular tubules along with massive connective tissue was observed in the serosa and subserosa. The glandular tubules were covered with mono-or multilayered epithelial cells with ciliary structures protruding into the glandular lumen. The connective tissue was composed of mesh-like fiber, fibroblast-like cells, and tortuous blood vessels. The glandular tubules and the connective tissue were similar to the glands and interstitial tissue in the endometrium. (J Toxicol Pathol 2001; 14: 313-315)

“…Such would be the case if the risk of a fecundity loss increases with each additional year of life or the cumulative 'wear and tear' associated with repeated parturitions. In fact, previous research has already shown that both age (van Wegenen, 1972;Hodgen et al, 1977;Graham et al, 1979) and parity (McCann and Myers, 1970;Bertens et al, 1982) are associated with a deterioration of the reproductive capacity of female macaques.…”

The reproductive performance of 760 free-ranging female rhesus monkeys (Macaca mulatta), 168 of whom were 20 years of age and older at the time observations were begun, was assessed. The monkeys were resident on Raccoon Key or Key Lois, two islands located in the Florida Keys, USA. During 1992 and 1993, live birth rates generally declined with age among the Raccoon and Lois females aged eight years and older. This age-related deterioration of female fertility was the result of proportionately more younger females bearing live young during successive birth seasons, and proportionately more older females experiencing an inability to bear live offspring even after a barren year. It is suggested that (1) older females may be more strongly inhibited by the suckling stimulus than are their younger peers, and (2) the risk of a permanent loss of fecundity increases with each additional year of life or parturition. The live birth rates of females aged 16-24 years were greater on Raccoon Key than they were on Key Lois, because the Raccoon females within this age range were more successful at bearing live offspring during successive birth seasons; the reason for this difference could not be determined. Inter-population differences in both the body condition of the females and the severity of female-female competition for access to males were not considered to be plausible explanations. It is possible that the difference in female fertility between the islands is the result of the greater age of the adult males on Key Lois, or the phytochemicals eaten by the females on Raccoon Key.

“…Except for a few spontaneous endometriosis [8], most cases in rhesus monkeys have been thought to be the sequela of hysterotomy or chronic effects of irradiation [1,3,6,7,[9][10][11][12]. Present two cases, however, were free from these treatment at least for 9years as far as we are concerned.…”

“…Endometriosis is not uncommon in rhesus monkeys, and it has been reported as a sequela to hysterotomy with additional effects of ovarian steroids [1,3,4,6,9,10] and as a latent effect of irradiation [1,6,7,9,11,12] . In most of the reported cases in rhesus monkeys, the lesion was limited to the wall of pelvic organs [1,3,[6][7][8][9][10]12] . The severe cases presented in this report are of particular interest due to widespread disseminationn of the endometrial tissues without prier histories of uterotomy nor irradiation.…”
