Effect of a chronic treatment for 60 days at low concentrations of HgCl₂ on body weight (g), absolute (g or mg) and relative (g/100 g or mg/100 g) weights of reproductive organs of male rats.

<p>Data are expressed as means ± SEM. The relative organ weight was calculated by use of the formula: organ weight/body weight ×100.
