Abstract

We investigated the temporal relationship between abdominal temperature, physical activity, perineal swelling, and urinary progesterone and estradiol concentrations over the menstrual cycle in unrestrained captive baboons. Using a miniature temperature‐sensitive data logger surgically implanted in the abdominal cavity and an activity data logger implanted subcutaneously on the trunk, we measured, continuously over 6 months at 10‐min intervals, abdominal temperature and physical activity patterns in four female adult baboons Papio hamadryas ursinus (12.9–19.9 kg), in cages in an indoor animal facility (22–25°C). We monitored menstrual bleeding and perineal swelling changes, and measured urinary progesterone and estradiol concentrations, daily for up to 6 months, to ascertain the stage and length of the menstrual cycle. The menstrual cycle was 36 ± 2 days (mean ± SD) long and the baboons exhibited cyclic changes in perineal swellings, abdominal temperature, physical activity, urinary progesterone, and estradiol concentrations over the cycle. Mean 24‐hr abdominal temperature during the luteal phase was significantly higher than during the periovulatory phase (ANOVA, F(2, 9) = 4.7; P = 0.04), but not different to that during the proliferative phase. Physical activity followed a similar pattern, with mean 24‐hr physical activity almost twice as high in the luteal than in the periovulatory phase (ANOVA, P = 0.58; F(2, 12) = 5.8). We have characterized correlates of the menstrual cycle in baboons and shown, for the first time, a rhythm of physical activity and abdominal temperature over the menstrual cycle, with a nadir of temperature and activity at ovulation.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In women and non-human primates with menstrual cycles, core body temperature fluctuates in accordance with the menstrual cycle rhythm.

  • In baboons, the higher body temperature persists into the menstruation phase despite the drop in progesterone.

  • The higher body temperature in baboons is unlikely to result from the actions of only progesterone.

    “These findings suggest that the higher body temperature is unlikely to be a result from the actions of only progesterone [25]”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
