Neurophysiological parameters show highly significant differences between sexes: the mean conduction velocities in ulnar (35.8 ± 6.4 versus 47.8 ± 6.4 m/s) and median (34.1 ± 7.3 versus 42.8 ± 8.8 m/s) motor nerves are markedly slower in males, and the corresponding mean CMAP amplitudes in ulnar (4.0 ± 2.9 versus 6.4 ± 2.4 mV) and median (2.6 ± 2.8 ve
