Per- and polyfluoroalkyl substances (PFAS) exposure in women seeking in vitro fertilization-embryo transfer treatment (IVF-ET) in China: Blood-follicular transfer and associations with IVF-ET outcomes
Science
6 Jun 2022 | Sci Total Environ
Based on their physicochemical properties, many PFAS can easily cross the blood-follicle barrier, but there was no significant association between PFAS concentrations and select in vitro fertilization outcomes.

Influence of Perfluoroalkyl Substances on Occurrence of Coronavirus Disease 2019
Science
24 May 2022 | Int J Environ Res Public Health
PFAS exposures occurring early in life may cause deleterious health effects later in life, including decreased antibody response and reduced disease resistance. Highest levels of both PFAS exposure and COVID-19 were found in the oldest populations.
