https://www.ncbi.nlm.nih.gov/m/pubmed/22552705/ Replicating past findings, no significant correlations between T and desire in men were apparent, but these analyses showed that the null association remained even when psychological and confound variables were controlled. Men showed higher desire than women, but masturbation frequency rather than T influenced this difference. Results were discussed in terms of challenges to assumptions of clear links between T and desire. It was suggested to me that progesterone levels are more crucial for higher sex drive and could account for why T levels beyond normal have no correlation with sex drive. Is this a plausible hypothesis? Are we examining the wrong androgen?
