A Danish study has shown that of 1558 Danish men, those with either a low or high BMI had significant differences in reproductive hormone levels and sperm count.
BMI is a measure of weight and height and is sometimes used as a defining criteria on being overweight (high BMI) or underweight (low BMI). The researchers did note that it could also be other underlying aspects of the causes of low or high BMI which may be the true cause of decreased sperm counts and sex hormones.
… and it doesn’t stop there
A study in Pennsylvania has shown that current alcohol use, the use of electric blankets and waterbeds all have a detrimental effect on male fertility. Men who used waterbeds were found to be four times more likely to be infertile than men who did not for example. The researchers found no link between the use of coffee, smoking, tea, exposure to vibrations and electric heaters and infertility.
