SUMMARY A technique for the measurement of five conjugated steroids (dehydroepiandrosterone sulphate, pregnenolone sulphate, testosterone sulphate, dihydrotestosterone sulphate and testosterone glucuronide) in human seminal plasma is described. The steroid sulphates and testosterone glucuronide were measured by radioimmunoassay after solvolysis and enzyme hydrolysis, respectively. In all cases the recognized criteria of assay reliability were fulfilled. In a group of men with established fertility, dehydroepiandrosterone sulphate had the highest concentration and testosterone sulphate had the lowest (mean levels of 1.04 μmoles/l and 1.52 nmoles/l, respectively). The levels of pregnenolone sulphate, dihydrotestosterone sulphate and testosterone glucuronide were 30.3, 4.37 and 38.8 nmoles/l, respectively. In all cases the levels of conjugated steroid exceeded the levels of the corresponding unconjugated compound.
