Pregnanediol glucuronide

Pregnanediol glucuronide, or 5β-pregnane-3α,20α-diol 3α-glucuronide, is the major metabolite of progesterone and the C3α glucuronide conjugate of pregnanediol (5β-pregnane-3α,20α-diol).^[1][2] Approximately 15 to 30% of a parenteral dose of progesterone is metabolized into pregnanediol glucuronide.^[1][2] While this specific isomer is referred to as pregnanediol glucuronide and is the most major form, there are actually many possible isomers of the metabolite.^[3][4]
