A new study shows that a mother's exposure to toxic PFAS "forever chemicals" during early pregnancies can lead to lower sperm count and quality later in her child's life.
The co-author of the study said that future reproductive capacity is defined as testicles develop in the first trimester of a pregnant woman's uterus.
Exposure to substances that mimic and interfere with hormones can have consequences for semen quality later in life.
Thousands of products are resistant to water, stains and heat with the help of a class of 12,000 chemicals. They are referred to as "forever chemicals" because they accumulate in humans and the environment and do not break down. There is a growing body of evidence linking them to serious health problems.
The study looked at semen characteristics and reproductive hormones in men who were born to women who provided blood samples during their first trimester.
It is the first to look for exposure to more than two PFAS compounds and to assess exposure during early pregnancy, which is the male reproductive organ's "primary developmental period".
Seven of the fifteen compounds found in the mothers blood were included in the study.
Adult men with lower sperm counts are more likely to be raised by mothers with higher levels of exposure. The amount of non-progressive sperm increased because of this exposure. Issues can lead to infertility.
98% of Americans have chemicals in their blood and can accumulate in the fetus. In a recent analysis of 40 studies of umbilical cord blood from around the world, it was found that PFAS were found in every sample.
Sgaard Tttenborg said that infertility rates are on the rise.
The results of our studies are important. The more we know, the more we can stop.
