Total testosterone, SHBG and calculated free testosterone were statistically not different in IR and NIR subjects, while SSPG values, by design, were much higher in IR subjects compared with NIR males; total testosterone, SHBG and calculated free testosterone were, by design, much lower in HYPOG subjects compared with EUG males and, as suspected, SSPG values were higher in HYPOG males than in EUG subjects.
