A new study conducted by researchers at University of Florence suggests that men who have larger testicles are at an increased risk of developing heart disease.
The researchers observed over 2,800 men who visited sexual health clinics and measured the size of their testicles and hormone levels and tracked their health over a period of seven years.
The researchers found that those who had larger testicles had higher levels of luteinising hormone, which is known to affect the size of the testicles, and were also more likely to develop heart disease, drink more alcohol, be heavier and have higher blood pressure.
"Although it is generally assumed that testis size can predict reproductive fitness, our results indicate that this objective parameter can provide insights also on overall health and cardiovascular disease risk. Further studies are needed for clarifying determinants and mechanisms of testis enlargement that could mediate the increased incidence of major adverse cardiovascular events", lead researcher Giulia Rasterelli said.
