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.
