Air pollution doesn’t only affect your lungs as new research suggests air quality may also be linked to a decrease in the number of eggs in women’s ovaries. It has long been known that environmental factors impact our reproductive systems, and multiple studies linked low sperm count with environmental indicators, but fewer examine the connection to ovaries. This newest study, presented at the European Society of Human Reproduction and Embryology is the first to look at the prevalence of eggs and not just fertility.
