Large-scale study finds decline in ovarian reserve related to PM and NO2 in atmosphere

Green Car Congress

A large-scale study has found that high levels of air pollution adversely effect ovarian reserve—a term widely adopted to reflect the number of resting follicles in the ovary and thus a marker of potential female fertility. Some studies have tried to make the connection between ovarian reserve (i.e., —Professor La Marca.
