Exposure to air pollution increases infertility risk, US study finds

Research shows common air pollutants can be detrimental to egg, sperm and embryo development

Maternal and paternal exposure to common air pollutants may increase the risk of infertility because it can be detrimental to egg, sperm and embryo development, new research in the US finds.

Previous papers have established that air pollution exposure probably contributes to infertility, but it has been unclear whether the toxins affected men or women because both parents face similar exposures. That also made it difficult to establish when in the conception process damage occurred.
