PFAS, now found in nearly all umbilical cord blood around the world, interfere with hormones crucial to testicle development
A new peer-reviewed Danish study finds that a mother’s exposure to toxic PFAS “forever chemicals” during early pregnancy can lead to lower sperm count and quality later in her child’s life.
PFAS – per- and polyfluoroalkyl substances – are known to disrupt hormones and fetal development, and future “reproductive capacity” is largely defined as testicles develop in utero during the first trimester of a pregnancy, said study co-author Sandra Søgaard Tøttenborg of the Copenhagen University Hospital.
