The study included 474 diabetic men from a screening of over 2,000. This is the largest study to date. Previous studies in this area have been much smaller, with 19, 163, 227 subjects.
Over half the diabetic men in the study with low testosterone reported a decreased ability to perform sexually. It should be noted that testosterone is important to general health and not only related to sexual drive or ability.
Dr. Sherwyn Schwartz, director of the Diabetes & Glandular Disease Clinic in San Antonio, Texas, and diabetes investigator is quoted as saying "Too many times people with diabetes have gotten the short end of the deal."
