Testosterone deficiency symptoms were assessed using the Aging Males\u2019 Symptoms Rating Scale, urological examination, and blood testing (for total testosterone, free testosterone, follicle-stimulating hormone, and luteinizing hormone). We excluded patients with congenital hypogonadism and any acquired disorders of the testes and genitalia. The definition of primary hypogonadism was based on the International Society for the Study of the Aging Male 2015 diagnostic criteria for hypogonadism.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Seven patients met the definition of primary hypogonadism\u2014a prevalence of 23.3% (95% confidence interval: 9.9\u201342.3).
