Men who have trouble conceiving may have the air they breathe to blame, a new study by Chinese researchers suggests.
Microscopic particles in the air called particulate matter (PM2.5) may affect the quality of sperm, which in turn can make it difficult to fertilize a woman's egg, the researchers said.
"Air pollution is associated with a significant drop in normal sperm shape and size, which may result in a significant number of couples with infertility," said lead researcher Xiang Qian Lao.
