  • Cadmium may impair prostate function as measured by Prostate Specific Antigen in semen: a cross-sectional study among European and Inuit men.

    • We investigated the association between cadmium in blood and the concentration of the prostate specific antigen (PSA) in semen, including the modifying effects of zinc or the CAG polymorphism in the androgen receptor (AR). Blood and semen samples were collected from 504 partners of pregnant women in Greenland, Poland and Ukraine. We found an inverse trend between cadmium and PSA (log (ß)= -0.121, 95% Confidence Interval (CI):-0.213; -0.029, P=0.0103) in Greenlandic men. Similar results were observed in men with a high number of CAG repeats (CAG 24) (log (ß)=-0.231, 95% CI:-0.363; -0.098, P=0.0009). Inverse trends between cadmium and PSA were found when semen zinc concentrations were below the median value for men from Ukraine and Greenland. These outcomes suggest that cadmium may impair prostate function, as measured by PSA in semen, while high zinc levels and a low number of CAG repeats protects against this action.

  • Environmental mercury exposure, semen quality and reproductive hormones in Greenlandic Inuit and European men: a cross-sectional study
  • 2013
  • Ingår i: Asian Journal of Andrology. - : Medknow. - 1008-682X .- 1745-7262. ; 15:1, s. 97-104
  • Tidskriftsartikel (refereegranskat)abstract
    • Several animal studies indicate that mercury is a male reproductive toxicant, but human studies are few and contradictory. We examined semen characteristics and serum levels of reproductive hormones in relation to environmental exposure to mercury. Blood and semen samples were collected from 529 male partners of pregnant women living in Greenland, Poland and Ukraine between May 2002 and February 2004. The median concentration of the total content of mercury in whole blood was 9.2 ng ml(-1) in Greenland (0.2-385.8 ng ml(-1)), 1.0 ng ml(-1) in Poland (0.2-6.4 ng ml(-1)) and 1.0 ng ml(-1) in Ukraine (0.2-4.9 ng ml(-1)). We found a significantly positive association between the blood levels of mercury and serum concentration of inhibin B in men from Greenland (beta=0.074, 95% confidence interval (CI)=0.021 to 0.126) and in an analysis including men from all three regions (beta=0.067, 95% CI=0.024 to 0.110). The association may be due to beneficial effects of polyunsaturated fatty acids (PUFAs), which are contained in seafood and fish. No significant association (P>0.05) was found between blood concentrations of mercury and any of the other measured semen characteristics (semen volume, total sperm count, sperm concentration, morphology and motility) and reproductive hormones (free androgen index (FAI), follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone and LHxtestosterone) in any region. In conclusion, the findings do not provide evidence that environmental mercury exposure in Greenlandic and European men with median whole blood concentration up to 10 ng ml(-1) has adverse effects on biomarkers of male reproductive health.
