“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.
‘It makes sense that exposure to substances that mimic and interfere with the hormones involved in this delicate process can have consequences for semen quality later in life,’ Søgaard Tøttenborg said.
PFAS are a class of about 12,000 chemicals typically used to make thousands of products resistant to water, stains and heat. They are called ‘forever chemicals’ because they accumulate in humans and the environment and do not naturally break down. A growing body of evidence links them to serious health problems such as cancer, birth defects, liver disease, kidney disease and decreased immunity.
The study, published on Wednesday in Environmental Health Perspectives, examined semen characteristics and reproductive hormones in 864 young Danish men born to women who provided blood samples during their pregnancies’ first trimesters between 1996 and 2002.” …
