The Circadian Pattern of Melatonin and Its Positive Relationship with Progesterone in Women

WEBLEY, G. E., LEIDENBERGER, F.·1986·The Journal of Clinical Endocrinology & Metabolism

Abstract

To investigate the possible role of melatonin in the regulation of the human menstrual cycle, the circadian pattern of melatonin was determined in the follicular and luteal phases of 10 normal women. Four-hourly sampling was used to derive a melatonin index which described the total exposure to melatonin for 24 h. This sampling procedure adequately represented the circadian melatonin output and demonstrated that pulses of melatonin secretion, inconsistent with a measured half-life of 47 min, did not exist. A significant increase (P less than 0.001) in the melatonin index was found in the luteal phase compared to that in the follicular phase. To investigate the influence of exogenous progestins on the melatonin pattern, repeated 24-h profiles were measured in 8 women taking the 3-phase contraceptive pill. There was a significant increase (P less than 0.01) in the melatonin index associated with an increase in the dose of progestin. These results are consistent with a positive relationship between melatonin and progesterone and suggest that changes in the circadian pattern of melatonin secretion, rising during the luteal phase with a fall before ovulation, may act as a modulator of cyclicity.

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.
