Biomarkers by gender

Regressions were determined for age-related human biological functions containing information for both genders. Their intercept T0 on the age axis (x) was used as a measure of the aging rate. The peak of the frequency distribution of T0 was consistent with earlier estimates. The frequency distribution of the ratio R of T0(women)/T0(men) peaked at unity. However, when the T0-values were divided into two groups, namely those relating to functions involving musculature vs. the rest, respectively, the ratio of R for musculature was <1 and that for the latter significantly >1. This suggests that men are the stronger gender when musculature is involved, but, more broadly, women are “biologically stronger”.
