Many patients receiving sustained-action narcotics during therapy for heroin addiction have symptoms of fatigue, depression, diminished libido, and impaired sexual function. They are rarely, however, evaluated for narcotic-induced hypogonadism, or treated with sex-hormone replacement. Studies are reviewed examining the influence of narcotic administration on sex-hormone levels. These document frequent, sometimes profound, deficiencies in many men and women treated with narcotics. We have documented improved quality of life during sex-hormone replacement therapy in patients with narcotic-induced hypogonadism, most of whom were receiving their narcotics for control of chronic pain. These studies suggest that similar hormone replacement therapy may assist patients receiving narcotics for treatment of heroin addiction.

We report the case of a 53 year old patient who was admitted with polyuria, polydipsia associated with fatigue, depression and sexual dysfunction. Central diabetes insipidus with hypogonadotrophic hypogonadism was diagnosed by a water restriction test and different static and dynamic hormonal dosages. Nodular thickening of the pituitary stalk was noted on the MRI and the biopsy permitted a histological diagnosis of infundibulitis.

In contrast to women, men do not experience a sudden cessation of gonadal function comparable to menopause. However, there is a progressive reduction in hypothalamic-pituitary-gonadal (HPG) function in aging men: testosterone (T) levels decline through both central (pituitary) and peripheral (testicular) mechanisms and there is a loss of the circadian rhythm of T secretion. In cohorts of men 75 years of age, mean plasma T levels are 35% lower than comparable young men, and more than 25% of men over 75 appear to be T-deficient. Such age-associated T deficiency, which has been termed 'andropause', is thought to be responsible for a variety of symptoms experienced by elderly men, such as weakness, fatigue, reduced muscle and bone mass, impaired haematopoiesis, oligospermia, sexual dysfunction, depression, anxiety, irritability, insomnia and memory impairment. However, it has been difficult to establish correlations between these symptoms and plasma T levels. Nevertheless, there is some evidence that T replacement leads to symptom relief, particularly with respect to muscle strength, bone mineral density, and haematopoiesis. Studies to date on the specific association between psychiatric symptoms, such as depressed mood, and T levels have been methodologically flawed. Overall, data suggest that although hypogonadism is not central to major depressive disorder (MDD), HPG hypofunction may have aetiological importance in mild depressive conditions, such as dysthymia.

Approximately half of patients with schizophrenia have at least one comorbid psychiatric or medical condition, worsening prognosis and contributing to the high rate of morbidity and mortality. Depression is associated with suicide, the leading cause of premature death in patients with schizophrenia; obsessive-compulsive symptoms may worsen prognosis; alcohol and substance use disorders are associated with a poor outcome; and comorbid medical conditions, including cardiac and pulmonary disease, infectious diseases, diabetes, hyperlipidemia, hypogonadism, and osteoporosis, are often underrecognized and undertreated. The new generation of antipsychotic medications has improved the potential outcome of patients with schizophrenia. Providing optimal treatment for patients and fully realizing the potential of these new agents require focused attention on detection, recognition, and treatment of comorbid psychiatric and medical conditions in patients with schizophrenia.

A reduced feeling of well being with unusual anxiety and irritability, nervousness, mood swings and a depressive state are often mentioned as the psychological symptoms of the age-related hypogonadism. However, psychological aspect of andropause has not yet been specifically studied and most data on psychological symptoms come from researchers' clinical impressions rather than from systematic studies. Therefore, it seems premature to assign them to the age-associated decline in testosterone levels. The implication of testosterone in psychological state has yielded mixed results. Among elderly men, lower testosterone levels were associated with depressive or dysthymic symptoms. Moreover, lower testosterone levels were reported in men with depression, independently of age. In contrast, some studies did not observe any significant difference in testosterone levels between depressed men and controls. Furthermore, several studies have suggested that testosterone replacement improved mood in hypogonadal men, but others did not, as in studies on eugonadal men. Several researchers have also suggested the potential use of testosterone as an antidepressant or adjuvant to current treatments in depressed hypogonadal men. The relationship between andropause and psychological symptoms such as depression is far from clear. Andropause may be associated with "minor depressive symptoms" that are not considered as pathological. Psychological manifestations do not appear specific to andropause and probably have a multifactorial origin.

In contrast to women, men do not experience a sudden cessation of gonadal function comparable to menopause. However, there is a progressive reduction in hypothalamic-pituitary-gonadal (HPG) axis activity in aging men: testosterone levels decline and there is a loss of the circadian rhythm of testosterone secretion. Such progressive HPG-axis hypofunctioning is thought to be responsible for some signs and symptoms that are common in elderly men such as fatigue, reduced muscle and bone mass, sexual dysfunction, and depression. Yet, such presumed hypogonadal sequelae have not been correlated with testosterone levels. Unlike the profound effects of replacement therapy in young men with frank hypogonadism, testosterone replacement in men with age-related mild hypogonadism is not apparently effective in reversing these symptoms. This article reviews the relationship between androgens, sexual function, and depression in aging men.

This study shows that endocrine and vascular etiologies of erectile dysfunction are more common in the older age group, whereas depression and marital discord are more common in the younger age group. There is considerable overlap between various factors pointing to the multifactorial nature of erectile dysfunction. Review of the treatment option chosen reveals that the invasive modalities were least common as compared with the popular vacuum tumescence device (although cumbersome) and testosterone replacement. Persons with low testosterone have an improved efficacy of sildenafil when hypogonadism is treated. Sildenafil with its ease of administration and high efficacy seems to be the logical first choice for most of the patients. If contraindications exist or treatment failures occur, other treatment options should be offered to patients.

Hypogonadism is highly prevalent in HIV-infected patients and has been associated with the late stages of AIDS and AIDS wasting. There are a number of studies exploring treatment options. Testosterone replacement, with the exception of the transscrotal delivery patch, has been observed to have a beneficial effect on lean body mass and body weight in hypogonadal and eugonadal men with the AIDS wasting syndrome. Resistance exercise training also has had favorable effects on body weight and muscle cell mass. In hypogonadal men with AIDS treated with testosterone replacement therapy, researchers noted a positive effect on depression scores.

The evaluation and treatment of male sexual dysfunction has evolved into a more extensive evaluation. This new evaluation should now include evaluation of hypogonadism, ejaculatory function, lower urinary tract symptoms, and depression. The evaluation may be readily accomplished with the use of questionnaires. The management of these entities is discussed, including the novel phosphodiesterase-5 for male erectile dysfunction. Inclusion of the partner in the evaluation and management scheme will provide added benefit and may produce a better outcome.

Age-related decline in testosterone levels is associated with a number of mild, nonspecific symptoms, including depressive symptoms. The relationship between depressive symptoms and testosterone levels is confounded by numerous factors, including medical illness, obesity, smoking, alcohol use, diet and stress, and is thus complex. Studies have not consistently supported an integral role of reduced testosterone levels in major depressive disorder, although levels may often be reduced in men with treatment-refractory depression and older men with dysthymia. Low testosterone levels may also increase the risk of incident depression in older males, although this may depend upon androgen receptor genetic polymorphisms. Testosterone replacement has demonstrated short-term tolerability and efficacy in augmenting antidepressants to alleviate treatment-refractory depression in adult males. Case studies support the potential need for maintenance therapy to maintain response. In a placebo-controlled trial, testosterone monotherapy was not effective in treating major depressive disorder in men with hypogonadism. However, in an open-label, noncomparative study, testosterone monotherapy appeared effective in treating late-onset but not early-onset major depressive disorder in older males. Testosterone therapy is not without potential for adverse effects, the most worrisome of which is the worsening of pre-existing prostate carcinoma. Oral, short- and long-acting parenteral, and transdermal patch and gel formulations are available. Testosterone has demonstrated usefulness in the treatment of a number of depressed populations, but further studies are needed to fully elucidate its role in the treatment of depressive syndromes in the aging male.
