“…We have confirmed that the fluctuations in plasma LH and FSH concentrations throughout the ovulatory menstrual cycle of the baboon are qualitatively similar to those of women (Wide et al, 1973., Mighissi et al, 1972., Sperff et al, 1973 and rhesus (Boorman et al, 1973., Yamaji et al, 1973 The pattern of baboon plasma LH found in this study is identical to that determined by homologous bLH radioimmunoassay (Stevens et al, 1970., Koyama et al, 1977.…”

“…Stevens et al (1970) were successful in developing a homologous radioimmunoassay with purified baboon pituitary extract for baboon luteinizing hormone (bLH), but this reagent did not become generally popular and the baboon FSH radioimmunossay remained undeveloped.…”

“…Entry to the large enclosures with free-ranging groups was not possible; there were no areas where individuals could be confined during dung collection and the aim was to ensure that the animals were disrupted as little as possible. Reproductive data in relation to swellings have been exceptionally well documented for baboons from blood samples and vaginal swabs (Stevens et al 1970, Kling & Westfahl 1978, Shaikh et al 1982, Bambra 1993. Such data may be more direct in their association with AGA swelling than are fecally recovered hormones which have both gut passage time lags and variance associated with diets (Wasser et al 1993(Wasser et al , 1994).…”

Factors affecting menstrual cycles and conception were explored for captive female olive baboons. We evaluated the relationship between the social environment and adequacy of the menstrual cycle in 55 non-conceptive and 21 conception cycles from 23 females. More abnormal cycles were expected for low-status females, and social stress levels were associated with variation in menstrual cycle length. Mean cycle length was 39.9 days (medianZ38) with a mean follicular phase duration of 23.7 (medianZ22) days. The duration of the follicular phase was more variable than that of the luteal phase (meanZ15.8 days). The first cycle after postpartum resumption of cycling was not markedly different from subsequent cycles in terms of duration or probability of conception. Dominance rank was one significant factor affecting female fertility. Low-ranking females experienced more cycles prior to conception, longer cycles once cycling was well established and had smaller sexual swellings (anogenital area) than did high-ranking females. Both acute and chronic stresses may play important roles in fertility outcomes for these baboons and further research is needed to understand the role of stress and subtle menstrual cycle abnormalities in female mammal fertility.

“…The considerable similarities in the anatomy, embryology and physiology of the fetopla cental-uterine units in baboon and man sug gest that the baboon is an ideal animal in grown and growth-retarded human neonates, volumes were strikingly similar for growthwhich to investigate problems of human re productive physiology [1][2][3][4][5][6][7][8][9]. Previous stud ies have shown that estimates of body water content and distribution arc quite similar in normally grown baboon and human neo nates, whether born prematurely or at term, to justify using the baboon fetus and mother as a model for investigations of human chemical development [3,4).…”

Body Water Estimates in Intrauterine-Growth-Retarded versus Normally Grown Baboon Neonates

Body water content and distribution were compared in 6 intrauterine-growth-retarded and 10 normally grown term baboon neonates. Growth-retarded baboons had larger mean antipyrine and corrected bromide spaces than their normally grown peers. Other water compartments were on the average similar in both groups. This pattern of comparisons is identical to that observed between normally grown and growth-retarded human neonates. Mean estimates for the various body water volumes were strikingly similar for growth-retarded neonates in baboons and humans.
