Male Hypogonadism (According to the Materials of the European Association of Urology)

Abstract

Male hypogonadism is a clinical syndrome which is the result of insufficient production of the sex hormone testosterone by the testicles and the number of spermatozoa. The article reveals modern views on the physiology and pathophysiology of testosteroneogenesis in the male organism, provides information on the etiology, pathogenesis, classification, diagnosis and modern treatment of hypogonadism in men. Literature on the results of global and European researches in recent years, as well as materials of the Guideline of the European Association of Urology for 2022, were used in the article. An individual therapeutic approach to each patient with hypogonadism was demonstrated. The importance of diagnosis of chronic and systemic comorbid diseases that cause the risk of hypogonadism, the need to determine the body mass index and the measurement of waist circumference, the size of the testicles, the penis and the presence of secondary sexual characteristic was established. The article includes necessary biochemical and instrumental studies for the diagnosis of hypogonadism. Specific contraindications for hormone replacement therapy are identified. Absolute contraindications for testosterone therapy are indicated: topically widespread or metastatic prostate cancer (PC), breast cancer of men; men who desire to have children; hematocrit level >54%; uncontrolled or poorly controlled stagnant heart failure. Relative contraindications include IPSS>19, initial hematocrit of 48-50 %, venous thromboembolism in a family history. The article also provides recommendations for testosterone therapy. It has been proven that testosterone therapy improves mild forms of erectile dysfunction (ED) and libido in men with hypogonade states; improves the frequency of sexual intercourses, orgasm and general pleasure; increases low-fat mass, reduces fat and improves insulin resistance; normalizes body weight, waist circumference and lipid profile; relieves the symptoms of depression in men with hypogonadism; improves bone mineral density. It has been demonstrated that the use of testosterone therapy in eugonadal men is not indicated. Testosterone therapy should be used as first-line treatment in patients with symptomatic hypogonadism and moderate ED. In addition, it is necessary to use a combination of type 5 phosphodiesterase inhibitors and testosterone treatment in more severe ED forms. It is also necessary to use standard medical treatments for severe symptoms of depression and osteoporosis. The therapy of hypogonadism, non-medication and medication, the necessary medicines and the peculiarities of their use are widely described. The article shows that weight loss due to low calorie diet and regular physical activity leads to a slight improvement in testosterone levels, testosterone gels and prolonged injection drugs are testosterone drugs have the best safety profile, and gonadotropin treatment can be used in men with secondary hypogonadism. It is noted that before the treatment with testosterone, it is necessary to treat organic causes of hypogonadism (for example, pituitary tumors, hyperprolactinemia, etc.), improve lifestyle and reduce body weight in persons with obesity; cancel drugs that can impair testosterone production. Much attention is paid to the risk factors by the treatment with testosterone. Testosterone therapy is contraindicated for men with secondary hypogonadism who wish fertility, men with active PC or breast cancer. Restoration of testosterone concentration in serum relieves the symptoms and signs of hypogonadism in men after 3 months of treatment. Therefore, testosterone therapy leads to improvement of the quality of patient’s life.
