What impact do higher levels of PASAs have on women's pregnancy rates?

Research from 2023 highlighted a concerning association between elevated levels of per- and polyfluoroalkyl substances (PASAs) in the blood of women in Singapore and their chances of achieving pregnancy and live births.

The study suggested that women with higher PASA blood levels faced a 30 to 40% lower chance of becoming pregnant and having a successful live birth within one year. Such findings underscore the potential reproductive hazards posed by these chemicals, which are commonly found in various environmental sources.

• This correlation indicates a significant public health concern regarding chemical exposure and reproductive health.
• Similar studies have linked PASAs to obesity due to their classification as endocrine disruptors.
• The impact of chemical exposure like PASAs may not only affect individuals but also extend to broader implications on population health and fertility rates.

The interplay between chemical exposure and reproductive outcomes emphasizes the need for continued research and awareness regarding the safety of substances encountered in daily life.
