What they found
Higher concentrations of organochlorines in cord blood and serum from childhood through adulthood were associated with increased proportions of chromosomal disomies. Specifically, PCB concentration in cord blood was linked to an extra Y chromosome, while PFAS concentrations in adulthood were associated with XX18 and YY18 disomies.
What they studied
Researchers investigated whether exposure to organochlorine compounds (OCs) and perfluorinated compounds (PFASs) from birth predicted sperm chromosomal abnormalities in young adulthood. They analyzed blood samples from 96 Faroese young men aged 22-24 years.
Takeaways
The abstract focuses on findings; it does not give personal how-to steps.
About this paper
This cohort study examined 96 Faroese young men from a birth cohort established in 1986-1987. Researchers analyzed current and previous serum, as well as cord blood, for various organochlorine and perfluorinated compounds. The findings provide new evidence that fetal and subsequent chemical exposures can have an enduring influence on male germ cell formation into adulthood.
