A modification of the method of Eberlein and Bongiovanni on thin layer chromatography was used to determine pregnanediol in the urine sample.

Urine pregnanediol excretion was in the pattern as investigated by other workers. The values rose in the latter half of the menstrual cycle, and fell prior to the onset …
