- Mercury exposure and male fertility: Studying the impact of environmental bioaccumulation on semen quality. Henriques, Magda Carvalho Santiago, Joana Patrício, António Herdeiro, Maria Teresa Loureiro, Susana Fardilha, Margarida Male Humans Mercury Adult Hair Semen Analysis Environmental Pollutants Environmental Exposure Fertility Bioaccumulation Semen Middle Aged Young Adult Spermatozoa In the last decades, growing evidence suggests a decline in male reproductive health, linked to a combination of lifestyle factors. Among environmental pollutants with potential reproductive toxicity, mercury (Hg) appears as a particularly concerning substance due to its ability to bioaccumulate in biological systems. However, controversial findings persist regarding the impact of Hg on fertility. This study assessed Hg exposure in men by analysing scalp hair samples and studying associations with semen parameters. Eligible men were recruited and data on sociodemographic, socioeconomic, lifestyle and reproductive health were obtained through a comprehensive questionnaire. Semen and scalp hair samples were collected for experimental analysis. Our findings revealed significant Hg bioaccumulation in all scalp hair samples, with 41 % exceeding 1000 ng/g, and 11 % surpassing 2000 ng/g. A significant positive correlation was observed between total Hg (THg) levels in scalp hair samples and sperm principal piece defects, as well as higher teratozoospermia index. Among the factors influencing Hg bioaccumulation, fish consumption may be an important contributor to elevated Hg levels. These results provided additional information for conducting Hg risk assessment for male reproductive health. Further and continuous monitoring of Hg exposure should be required to prevent possible adverse effects on male reproduction.
