Studies find that male fertility is diminishing, with sperm counts decreasing globally every year in the past few decades. Scientists have been searching why this is occurring, suggesting a number of possible causes (e.g., environmental pollutants, pesticides, microplastics, endocrine disruptors, lifestyle habits.).
Recent studies are suggesting that pollution, especially air pollution, may be also be contributing to the problem of reduced male fertility. Researchers are finding regional differences in sperm count and quality.
Two recent studies presented similar findings at the recent European Study of Human Reproduction this past week, with both finding that where you live could have a bigger effect on sperm count, sperm quality, and fertility than lifestyle habits. In other words, the pollution in the area you live (air pollution or other environmental contaminant) has an effect on fertility - that is, sperm count and quality. [Studies show that lifestyle habits are also important.]
From Medical Xpress: Men living in different regions show marked differences in sperm quality despite similar lifestyles, novel study finds
A new study has found substantial regional differences in sperm quality, with men in the highest-performing region recording almost double the total motile sperm count of those in the lowest-performing region. ...continue reading "Air Pollution and Male Fertility"
