During their lifetime, 20% of men will suffer from a fracture secondary to osteoporosis, and morbidity and mortality of a hip fracture in men are more severe than in women.

Hypogonadism can be found in patients diagnosed with prostate cancer who are receiving androgen deprivation therapy, but can also be discovered in patients with male infertility or erectile dysfunction. Urologists have central role in men's health aftercare, and therefore have key role in the screening and in the multidisciplinary treatment of osteoporosis and osteopenia.
