BACKGROUND: Lead is an industrial heavy metal that can decrease sperm motility.
OBJECTIVE: The aim was to investigate the protective effects of calcium against lead on motility of spermatozoa.
MATERIALS AND METHODS: In total 40 adult male Swiss white mice were randomly divided into 5 groups (control, lead of 1(st) wk, lead of 2(nd) wk, lead/calcium of 1(st) wk and lead/calcium of 2(nd) wk). The lead groups of mice were injected by a single dose of lead acetate (200 mg/kg) intraperitoneally. Lead/calcium groups of mice were injected by a single same dose of lead acetate along with three doses of 80 mg/kg calcium chloride. The control group of mice was injected only with same volume of distilled water through the same route. Mice of 1(st) and 2(nd) wk groups were sacrificed through cervical dislocation one and two weeks after injections respectively.
RESULTS: Mean of the progressive motile spermatozoa of cauda epididymis in lead/calcium group of the first week was higher than the lead group of the first week and this difference was significant. There was not any significant difference among weight of testes and epididymides of all groups.
CONCLUSION: It can be concluded that calcium can decrease the effects of lead on sperm motility.
