NEW YORK (CBS NEWS) - Unhealthy habits may not have a factor in sperm count, according to a new study. Scientists from the Universities of Manchester and Sheffield have discovered that lifestyle choices such as smoking or weight may have no affect the number of swimming sperm a man has. Currently, organizations such as the National Institute for Clinical Excellence and the Mayo Clinic claim that “general health and lifestyle issues,” such as poor nutrition, obesity or use of alcohol, tobacco and drugs could cause male infertility.
“This potentially overturns much of the current advice given to men about how they might improve their fertility and suggests that many common lifestyle risks may not be as important as we previously thought,” Dr. Andrew Povey, from the University of Manchester’s School of Community Based Medicine, said in the press release.
Reasons for male infertility can include abnormal sperm production or function, problems with sperm delivery, overexposure to environmental factors — including pesticides, chemicals or heat — and damage caused by cancer and cancer treatments, according to the Mayo Clinic.
