Male hypogonadism guidelines 2010 gmc – Testosterone deficiency: treat men who have bothersome symptoms

We suggest that when clinicians institute T therapy, they aim at achieving T concentrations in the mid-normal range during treatment with any of the approved formulations, taking into consideration patient preference, pharmacokinetics, formulation-specific adverse effects, treatment burden, and cost.

Introduction

Testosterone T is the major anabolic hormone in men as well as a key player in maintaining normal reproductive and sexual function. However, also in men with more severe obesity and low free TS levels, gonadotropin levels remain normal to only mildly elevated, indicating that at least in these men there is a central downregulation of the hypothalamic-pituitary-gonadal axis. No patient had a urological event prostate cancer or voiding dysfunction. Hildreth et al, [ 94 ]. With respect to clinical entities such as sarcopenia and frailty, the available literature is difficult to compare owing to the use of different operating definitions.

In a longitudinal study from the Concord Health and Ageing in Men Project study, with men at baseline and at 2-year follow-up, whereas baseline levels of total guldelines calculated free T, DHT, E2, and estrone did not predict a decline in sexual function, the decline of total and calculated free T but not of DHT, E2, or estrone during follow-up was associated with a decline in sexual activity and desire, but not in erectile function. Clin Endocrinol Oxf. This long-prevailing misconception is likely to be one of several explanations for the rather limited and mostly only recent evidence from controlled trials on T therapy in older men. Ng et al, [ 33 ].

Low free testosterone is associated with hypogonadal signs and symptoms in men with normal total testosterone. However, negative findings on the mechanisms underlying T effects on erythropoiesis have been published as well Both aspartate aminotransferase and alanine aminotransferase decreased significantly. Men with an unevaluated prostate nodule or induration, or raised PSA, should have this fully investigated prior to starting treatment with testosterone.

Testosterone replacement therapy with long-acting testosterone undecanoate improves sexual function and quality-of-life parameters vs. Hypogonadism and fertility issues Exogenous testosterone reduces endogenous testosterone production by negative feedback on the hypothalamic-pituitary-gonadal axis. In at-risk populations type 2 diabetes, smokers, obese, thrombophilic conditions caution should be exercised in prescribing short-acting intramuscular formulations [ ]. It is suggested that low testosterone is a biomarker for a poor health condition and as such is a marker for increased risk of cardiovascular disease [ ].

Hypothalamic-pituitary-testicular axis disruptions in older men are differentially linked to age and modifiable risk factors: the European Male Aging Study. During puberty, rising testosterone levels result in the development of male secondary sex characteristics, comprising deepening of the voice, development of terminal body hair, stimulation of hair growth in sex-specific regions, facial hair, increasing penile size, increase in muscle mass, bone size and mass, growth spurt induction and eventually closing of the epiphyses.

In milder cases of androgen deficiency, as seen in patients with Klinefelter syndrome, pubertal development can be normal, incomplete or delayed, resulting in a more subtle phenotypic picture. The undifferentiated gonads develop into a foetal testis through expression of multiple genes, including the sex-determining region of the Y chromosome SRY gene complex and the SOX genes [ 14 ].

Normalization of testosterone level is associated with reduced incidence of myocardial infarction and mortality in men. Such changes guodelines compatible with the known reduced T negative feedback to kisspeptin neurons and may participate in the elevated LH levels in the primary hypogonadism of aging men. Testosterone supplementation did not show consistent benefit for cardiovascular risk, sexual function, mood and behavior, or cognition. In analyses adjusting for stroke risk factors, which had a somewhat limited statistical power, total and free T were not associated with stroke risk. The role of DHT in these relationships has been inadequately explored.

We recommend T therapy for men with symptomatic T deficiency to induce and maintain secondary sex characteristics and correct symptoms of hypogonadism after male hypogonadism the hypogonadusm benefits and risks of therapy and of monitoring therapy and guideliines the patient in decision making. Table 3: Clinical symptoms and signs suggestive for androgen deficiency Clinical symptoms and signs suggestive for androgen deficiency: Reduced testis volume Male-factor infertility Decreased body hair Gynaecomastia Decrease in lean body mass and muscle strength Visceral obesity Metabolic syndrome Insulin resistance and type 2 diabetes mellitus Decrease in bone mineral density osteoporosis with low trauma fractures Mild anaemia Sexual symptoms: Reduced sexual desire and sexual activity Erectile dysfunction Fewer and diminished nocturnal erections Cognitive and psychovegetative symptoms: Hot flushes Changes in mood, fatigue and anger Sleep disturbances Depression Diminished cognitive function The most prevalent symptoms of male hypogonadism in ageing men are reduced sexual desire and sexual activity, erectile dysfunction, loss of vigour and changes in mood [ 1252 ]. As hypogonadism increases with age and is significantly associated with various comorbidities such as obesity, type 2 diabetes, hypertension, osteoporosis and metabolic syndrome, the physician is increasingly likely to have to treat hypogonadism in the clinic.

They reported mixed and overall inconclusive findings of either an inverse relationship with serum free T or no association independent of known CV risk factors. This practice is generally not challenged, even though for historical and ethical reasons it is mostly based on a rational concept and clinical experience rather than controlled data. An important point to address is that most of these studies report on total serum TS levels, which are largely determined by the hepatic production of SHBG. Kapoor et al, [ ].

Subjects said to be randomized, but randomization method and number of subjects per group not given. Experimental studies, especially on the brown Norway rat, have also elucidated the extrinsic factors that may participate in the aging-related decline of Leydig cell function. However, the origin of anemia in the elderly is multifactorialand the decrease in androgen exposure probably only accounts for a minor part of the overall decline in erythropoiesis in aging men. Although the currently available immunoassays for SHBG and gonadotropins appear adequate, a fair amount of uncertainty and controversy still surrounds the approaches on how to monitor circulating T levels, both total and free. No change in handgrip, knee extensor, and knee flexor strength, leg extensor power, step height.

Adult-onset hypogonadism Adult-onset hypogonadism is defined as testosterone deficiency, usually associated with clinical symptoms or signs in a person who has had normal pubertal development and, as a result, developed normal male secondary sex characteristics. Symptoms that have been associated with adult-onset hypogonadism are summarised in Table 3.

Reduced sexual desire and sexual activity. Eriksson, J. Observational studies have reported that testosterone treatment improves survival when compared to men who were not treated [ 78]. Testosterone treatment aims to restore testosterone levels to the physiological range in men with consistently low levels of serum testosterone and associated symptoms of androgen deficiency.
