There are new developments in the study of male fertility. In Italy, a recent massive research study that involved over 5,000 males. It focused on analyzing sperm counts and overall health.
The study discovered that males with low sperm counts usually have more health issues. Infertile men are more likely to have significant co-existing health problems or risk factors that can impair quality of life and shorten their lives. About half of the men who had low sperm counts were 1.2 times more likely than those with normal sperm counts to have greater body fat (bigger waistline and higher body mass index, or BMI); higher blood pressure (systolic, or top reading); "bad" (LDL) cholesterol and triglycerides; and lower "good" (HDL) cholesterol. They also had a higher chance of metabolic syndrome, a cluster of these and other metabolic risk factors that increase the chance of developing diabetes, heart disease and stroke.
According to this study, sperm count is an indicator to the general health of a male. Dr. Alberto Ferlin, mediator of the study, urges males that are receiving fertility treatments to also explore other health issues.
