Abstract

Background: Male INFERTILITY is affected by several factors. LEAD is one of the heavy metals more bioavailable than usually modifies the sperm quality in humans.Objective: The aim of this study was to establish the role of LEAD in semen quality in ENVIRONMENTALly exposed men.Materials and Methods: Semen and blood samples were obtained from two groups: the exposed group (EG=20) and the non-exposed group (NEG=27). Two semen aliquots were used, one to evaluate SPERMATIC QUALITY and the other for LEAD determination. Blood (PbB) and semen LEAD (PbS) determination was performed by atomic absorption spectrophotometry.Results: The PbB concentration was significantly greater in the EG, 10.10±0.97 mgdL-1 than in the NEG, 6.42±0.38 mgdL-1 (p<0.01), as well as the PbS concentration, with 3.28±0.35 and 1.76±0.14 mgdL-1 in the EG and NEG respectively (p=0.043). A significant correlation between PbS and PbB concentration in the EG was found (r=0.573, p=0.038). Overall, the SPERMATIC QUALITY was lower in the EG than in the NEG. Specifically, there were significant differences in the spermatic concentration [EG=43.98±6.26 and NEG=68.78±8.51X106 cellmL-1 (p<0.01)], motility [EG=49±7 and NEG=67±4% (p=0.029)], viability [EG=36.32±3.59 and NEG=72.12±1.91% (p<0.01)] and abnormal morphology [EG=67±18 and NEG=32±12% (p<0.01)]. In the immature germ cells (IGC) concentration differences were found only for A cells (EG=8.1±1.1x100 and NEG=3.2±1.9x100 spermatozoa) (p<0.01) and for Sab cells (EG=3.4±2.2x100 and NEG=1.1±1.0X100 spermatozoa) (p=0.041).Conclusion: These results suggest that chronic ENVIRONMENTAL exposure to low levels of LEAD adversely affect the SPERMATIC QUALITY.
