Increased exposure to air pollution significantly increases the risk of infertility, according to a study published in the journal Environment International.
In China, it was found out that people living with moderately higher levels of small-particle pollution had a 20% greater risk of infertility.
Pollution particles are known to cause inflammation in the body, which can cause damages to egg and sperm in women and men respectively.
In US, a study revealed that exposure to air pollution was associated with a lower number of maturing eggs in women.
Air pollution also increases others risks such as premature birth and low birth weight.
