Effects of Oral Progesterone on Three Indexes of Ovulation... 

If progestational potency as judged by this assay is an index of fertility-controlling potency, we would seem to have a formidable array of orally active compounds. The especially high potency of two of them (JX and XII) would seem to assure us of especially effective substances. Furthermore, in the rabbit the oral effectiveness of these compounds as ovulation inhibitors roughly parallels the progestational efficiency (Pincus and Merrill, 1959).

This is the major urinary metabolite of progesterone. It can be measured in urine as an index of placental function in pregnant females, and to detect ovulation in non-pregnant females (see progesterone). It can be measured by gas chromatography, radioimmunoassay or chemical means (by its reaction with sulphuric acid following its isolation by column chromatography).
