Are men living in cities more likely to have lower sperm counts?
A new study published in the Journal of Human Reproduction Update, focussed on men living in North America, Europe, Australia and New Zealand, revealed a 52% decline in sperm concentration and 59% decline in total sperm count over a 40-year period. Researchers found a decline in sperm count of 1.6% per year for men living in industrialized, Western countries. Compared to men kiving in South America, Asia and Africa, no significant decline in sperm count or sperm concetration was observed.
Some researchers believe poor eating habits leading to obesity and higher exposure to chemicals may be to blame for the decline. Obesity and low mobility, according to a the EPA, are a plausible explanation. Scientists agree, questions around sperm quality warrant continued research.
