Conditional Recommendations also can be supported by any evidence strength. The baseline assessment of prostate cancer risk should consider risk factors, such as age, family history increased risk in men having a first-degree relative with prostate cancer , race increased risk in African Americans , prior biopsy history, elevated PSA levels, and positive prostate examination results.

J Clin Endocrinol Hypogoandism ; 90 3 : — If a decision is made to treat hypogonadism in men with chronic cardiac diseases it is essential that the patient is followed carefully with clinical assessment and testosterone and haematocrit measurements, on a regular basis. Yuen K. Studies are often specifically powered and designed to address a key efficacy endpoint, such as a particular symptom improvement, and not to address secondary symptom improvement or adverse events.

Panel members received no remuneration for their work. Finally, a randomized trial of 76 men mean age Clinicians should make note of any patient-reported symptoms, particularly those listed in Table 5 and conduct a hypogonadism definition examination to assess patients for signs related to low testosterone. The general trend indicated that higher doses of testosterone were more likely to result in azoospermia than lower doses, however a dose-response effect was not consistently seen. Open in new tab. Outside the United States, oral T undecanoate and a matrix transdermal T patch are available for clinical use in many countries; physicians should follow the drug regimens approved in those countries. RCTs have failed to categorically define if testosterone therapy increases the incidence of MACE when compared to placebo.

Radiation to the brain that exposes the pituitary gland can also result in pituitary dysfunction and low testosterone. In-vitro experiments have shown that prostate cancer cells fail to proliferate in the absence of testosterone; once testosterone is introduced, an initial proliferative response is observed followed by a plateau after a certain testosterone concentration is reached. Only three men treated with T and one treated with placebo were diagnosed with prostate cancer during those 2 years.

Am J Physiol. Hypergonadotropic hypogonadism, definitiion is not a contraindication to begin testosterone therapy, can result from a number of conditions, including congenital abnormalities KS being the most commoniatrogenic causes e.

Over a mean duration of The half-life for IM testosterone was also shorter at hours versus hours for SQ testosterone. At the present time, there are insufficient data available to predict which men with ED are most likely to respond to testosterone therapy.

  • Three others did stop testosterone in response to the PSA bounce, two of whom had negative prostate biopsies. The aim of clinical practice guidelines is to analyse complex or incomplete evidence and provide clear guidance to practicing physicians.

  • Transference may be mitigated by washing hands, covering the application site with clothing, and washing the region prior to anticipated direct contact with others.

  • Consider assessing testosterone in men with a disease or treatment in which testosterone deficiency is common and in whom treatment may be indicated.

Mulhall, MD; Landon W. Despite the homogenous nature of the trials included, it was noted that there was a risk of publication practice guidelines hypogonadism definition since it is possible that trials favoring testosterone therapy might remain unpublished. In both trials, scores in the placebo cohort increased by a relatively large amount placebo: 6. Endocrine Society committees and members and the cosponsoring organization were invited to review and comment on preliminary drafts of the guideline. Active Surveillance. From a clinical standpoint, it dictates that there is a testosterone threshold beyond which prostate cells benign or malignant cease responding.

Soisson, V. When hypogonadism is present, measure luteinizing hormone LH and follicle-stimulating hormone FSH to distinguish between primary hypogonadism low testosterone, high LH and FSH and secondary hypogonadism low testosterone, normal or reduced LH and FSH strong recommendation, moderate-quality evidence. The physician is encouraged to carefully follow all available prescribing information about indications, contraindications, precautions and warnings. Thus, there are insufficient data to establish a causal link between T therapy and cardiovascular events. Male hypogonadism—rebadged by some as testosterone deficiency syndrome—is a clinical and biochemical diagnosis of increasing worldwide interest. Birth Defects Orig Artic Ser.

Practice guidelines case reports have identified virilization and precocious puberty in children as well as hyperandrogenism in women following accidental exposure to topical testosterone. ED is one of the primary reasons that men seek testosterone treatment. T administration has also been associated with improvements in maximal voluntary strength The Shores study was an observational study of 1, men mean age For men 55—69 years of age and for men 40—69 years of age who are at increased risk for prostate cancer who choose prostate monitoring, perform digital rectal examination and check PSA level before initiating treatment; check PSA and perform digital rectal examination 3—12 mo after initiating T treatment, and then in accordance with guidelines for prostate cancer screening depending on the age and race of the patient.

Clinicians should be aware that symptomatic gynecomastia or other breast symptoms are an uncommon side effect in men on testosterone therapy. Some of the cancers were detected during the treatment phase, while others were detected during post-study follow-up. When the goal of treatment is to replace T, treating men with prepubertal onset of hypogonadism is similar to treating men with postpubertal onset hypogonadism, although some practitioners and patients may elect to start T treatment at a lower dosage initially and gradually increase the dose over many months to avoid sexually disturbing thoughts.

Men were excluded if they had a history of prostate cancer, had undergone prostate surgery, or were taking finasteride or other drugs that altered PSA. One subject from the testosterone practice guidelines was diagnosed with prostate cancer, which was deemed possibly treatment related. Study Population. Prior to offering testosterone therapy, clinicians should measure hemoglobin and hematocrit and inform patients regarding the increased risk of polycythemia. Therefore, clinicians should measure total testosterone concentrations on two separate mornings when the patient is fasting. T is not an approved treatment for osteoporosis or for reducing fracture risk. This search included articles published between January 1, - February 6, and yielded 15, references, enrolling approximatelymen of which were used to support guideline statements.

Overall, seven studies reported no benefits on QoL in men using testosterone therapy compared to placebo,,while five studies demonstrated improvements. A challenge in making the diagnosis of testosterone deficiency is that many of the symptoms reported by patients are non-specific and might be related to conditions other than low testosterone. These forms are primarily rare defects and will not be further discussed in detail in these guidelines.

The Xu meta-analysis of 27 randomized placebo-controlled trials pointed to an increase in cardiovascular risk in men practice guidelines hypogonadism definition testosterone therapy, although the results were statistically insignificant. Khoo TK. Purpose Testosterone testing and prescriptions have nearly tripled in recent years; however, it is clear from clinical practice that there are many men using testosterone without a clear indication. According to a recent retrospective study on hypogonadal men with previous history of prostate cancer receiving testosterone following cancer diagnosis, treatment was not associated with increased overall or cancer-specific mortality, but testosterone treatment was more likely to be prescribed in patients undergoing radical prostatectomy for well-differentiated tumours [ ]. The advantage of the use of PDE5Is for erectile dysfunction is that these drugs are usually very effective and work fast.

Study limitations included failure to report baseline erectile function, failure to identify a population of men with isolated ED, study population heterogeneity, and inconsistent inclusion criteria across studies. However, EMAS also found the overwhelming contribution to the apparent age-related decline in T levels to reside not in chronological aging per sebut rather in the accumulation of age-associated co-morbidities, such as obesity, resulting in suppression of LH secretion [ 8 ]. Case-finding paradigms: apart from men with core clinical features or risk factors sexual dysfunction, infertility, gynecomastia, vasomotor symptoms, anemia, osteoporosis, absent or incomplete secondary sexual characteristic, characteristic syndromic features, or history of tumor, surgery, chemotherapy, or ionizing radiation affecting the HPT axiswho else—if anybody—should be screened for MH? The ES recommends case detection for men deemed to be at increased risk of having hypogonadism and likely to benefit from T therapy, such as those with low libido, erectile dysfunction, infertility, HIV-associated weight loss, osteoporosis or low-trauma fracture, a history of anabolic steroids use, or using opioids or other drugs or substances that affect T production or metabolism.

Practice guidelines hypogonadism definition meta-analyses have evaluated the impact of testosterone therapy on lipid profiles. These recommendations, however, are not based on current testosterone defknition formulations and contrast with pharmacokinetic data available. The risk corresponded to an additional 10 cases per 10, person-years, which, while low in absolute terms, raised concern about using testosterone therapy in men who may be at increased risk for VTE prior to commencement of therapy. AIs should in general not be used for extended periods of time due to concerns regarding loss of BMD. Retrospective analyses of data using electronic medical records have also been inconclusive and are similarly constrained by the lack of randomized allocation and prospective adjudication of cardiovascular events, confounding by indication, and heterogeneity of patient populations, T doses, and intervention durations 96—

Each class of alternative therapy has a different buidelines of action: hCG acts as an LH agonist and stimulates Leydig cell production of testosterone, AIs block the conversion of testosterone to E2, and SERMs inhibit the negative feedback of E2 on LH production at the level of the hypothalamus and pituitary gland. T therapy in healthy hypogonadal men increases areal and volumetric vertebral and femoral BMD and vertebral and femoral bone strength 69—71but there are no studies on the effects of T on fracture risk. The authors report that clomiphene resulted in significantly higher serum testosterone levels than anastrozole, but anastrozole resulted in significantly higher T:E ratios than clomiphene. The task force commissioned two systematic reviews and used the best available evidence from other published systematic reviews and individual studies.

TAKE-HOME MESSAGE

The knowledge that hypogonadism and erectile dysfunction are biomarkers of cardiovascular disease demonstrates that patients should be assessed for cardiovascular risk factors and where appropriate referred to cardiology. The Panel urges clinicians to use their clinical judgment in the management of such patients. This content does not have an Arabic version. Two of the retrospective studies included in the FDA review pointed to an increased risk of cardiovascular events in men on testosterone therapy. Androgen deficiency increases slightly with age also in healthy men [ 1011 ].

Men receiving methadone maintenance therapy are definitin high risk of developing opioid-induced hypogonadism, whereas hyogonadism prevalence of opioid-induced hypogonadism is substantially lower with buprenorphine. However, most meta-analyses have not shown a statistically significant association between T treatment and cardiovascular events, MACE, or deaths. Other population based studies have attempted to measure prevalence, but have not used standard methodology, which makes arriving at a definitive number of testosterone deficiency difficult. Testosterone concentrations exhibit significant diurnal and day-to-day variations and may be suppressed by food intake or glucose. Although the differences between the two treatment arms with regard to prostate and cardiovascular adverse outcomes were not statistically significant, the number of participants and the treatment duration in the TTrials were not sufficient to draw conclusions about the effect of T on these adverse outcomes. Testosterone therapy in hypogonadal men who have T2DM should follow the same treatment and monitoring plan as hypogonadal men without T2DM.

Heart, Quality of Life. Therefore, until a harmonized reference range is established, the lower hypogonadism definition established by the laboratory may be used. A case for clarity, consistency, and helpfulness: state-of-the-art clinical practice guidelines in endocrinology using the grading of recommendations, assessment, development, and evaluation system. Glucose and food intake suppress T concentrations 20 While mid-cycle testing is convenient for patients, there may be value in assessing peak level hours after injection as the adverse events e.

Guidelines

Large pituitary tumors, functioning or non-functioning, practice guidelines hypogonadism definition require surgical extirpation because of mass effect. Eur Heart J, Observational studies indicate that testosterone therapy does not increase the risk of developing prostate cancer or result in more aggressive prostate tumours [ 99,]. Obes Rev, Nonspecific symptoms and signs associated with testosterone deficiency.

Male hypogonadism is a condition in which the body doesn't produce enough of the hormone that plays a key role in masculine growth and development during puberty rpactice or enough sperm or both. While there are three injectable drugs, two of them are short-acting and one is long-acting. There have been no RCTs that were large enough or long enough to determine the effects of T-replacement therapy on major adverse cardiovascular events MACE. Grading quality of evidence and strength of recommendations. At the end of the study, serum testosterone levels rose in those men receiving testosterone therapy; however, no rise in testosterone levels were seen within the prostate tissue itself. Do not use testosterone therapy in patients with male infertility or active child wish since it may suppress spermatogenensis.

Because of the considerable controversy over prostate cancer screening and monitoring, clinicians should discuss the risks and benefits of prostate cancer screening and monitoring and engage the practice guidelines hypogonadism definition in shared decision making prior to starting T treatment Systemic illness a. Although the absolute risks of POME and anaphylaxis require ongoing study, data from patients undergoing 3, injections 1, mg in 4 mL over a period of 3. Gonadal steroid-dependent effects on bone turnover and bone mineral density in men. In men deemed to have secondary hypogonadism, additional diagnostic evaluations may be needed to exclude hyperprolactinemia, head trauma, iron overload syndromes, hypothalamic or pituitary tumors, and other infiltrative or destructive hypothalamic—pituitary diseases, as well as genetic disorders associated with gonadotropin deficiency. Where gaps in the evidence existed, the Panel provides guidance in the form of Clinical Principles or Expert Opinion with consensus achieved using a modified Delphi technique if differences of opinion emerged.

During the subsequent year of follow-up, eight men from the placebo group and one man hypognoadism had been on treatment were adjudicated to have had a definite myocardial infarction. If the testosterone concentration is increased further, rather than further proliferation, the cells reduce their rate of proliferation. Hypogonadotropic hypogonadism is common in men receiving chronic enteral, parenteral, or intrathecal opioid medications for pain management Studies that randomized overweight or obese men to diet and exercise programs had significantly greater increases in total testosterone levels than men who underwent calorie reduction or exercise programs alone.

  • Significant improvement of depressive symptoms in men treated with testosterone undecanoate was reported hypogonadism definition a recent randomised trial [ 74 ]. All guidelines agree that the best way to measure T is by liquid chromatography mass spectrometry, but acknowledge that this may not be available in every institution and; hence, a high-quality validated immunoassay may instead need to be relied upon.

  • In men deemed to have secondary hypogonadism, additional diagnostic evaluations may be needed to exclude hyperprolactinemia, definition trauma, iron overload syndromes, hypothalamic or pituitary tumors, and other infiltrative or destructive hypothalamic—pituitary diseases, as well as genetic disorders associated with gonadotropin deficiency. In men determined to have androgen deficiency, we recommend additional diagnostic evaluation to ascertain the cause of androgen deficiency.

  • Selection of optimal prostate specific antigen cutoffs for early detection of prostate cancer: receiver operating characteristic curves.

AAS withdrawal after an extended period of high-dose AAS use is associated with marked suppression of endogenous T concentrations and severe symptoms of AAS withdrawal hypogonadism, including sexual dysfunction, fatigue, depressed mood, and sometimes clinical depression and even definitipn Although study exclusion criteria included uncontrolled hypertension, unstable angina, myocardial infarction within the past three months, and congestive heart failure, there was a higher rate of hyperlipidemia and statin use at guidelinds in the testosterone therapy group as compared to the placebo group. We recommend making a diagnosis of hypogonadism only in men with symptoms and signs consistent with testosterone T deficiency and unequivocally and consistently low serum T concentrations. Effect of testosterone treatment on body composition and muscle strength in men over 65 years of age. Despite clinical experience that some men with testosterone deficiency and diabetes improve glycemic control with testosterone therapy, nine RCTs that assessed the impact of testosterone therapy on measures of diabetes demonstrated that there were no significant differences in HbA1c levels between those who were treated with testosterone and controls. We recommend measuring fasting morning total T concentrations using an accurate and reliable assay as the initial diagnostic test.

Older men are as responsive as young hypogonadis, to the anabolic effects of graded doses of testosterone on the skeletal muscle. Because of the lack of consensus on the extent to which hypogonadism is an important public health problem, as well as the lack of data on the performance characteristics of candidate screening tools, we do not recommend population screening. Causes of primary hypogonadism include Klinefelter syndrome KScryptorchidism, some types of cancer chemotherapy, radiation to the testes, trauma, torsion, infectious orchitis, HIV infection, anorchia syndrome, and myotonic dystrophy 5. The impact of testosterone therapy on improving depressive symptoms has been reported in nine RCTs using various assessment measures, including the Hamilton Rating Scale for Depression, Beck's Depression Inventory, and Patient Health Questionnaire-9 questionnaires.

Lewis, MD. There were inconsistently defined end points to categorize severe cardiac events, which included 'softer' endpoints e. Although these new scales are psychometrically more robust than previous instruments, clinical experience with them is limited. Testosterone deficient patients should be informed that low testosterone levels place them at risk for these major cardiovascular events and clinicians should assess all testosterone deficient patients for ASCVD risk factors, both fixed e. Therefore, it is important to establish a standardized monitoring process and criteria for referring patients receiving T treatment for possible prostate biopsies to minimize the risks and expense of unnecessary testing. Clinicians should not use direct analog-based free testosterone immunoassays, as they are inaccurate.

The metabolic syndrome in central hypogonadotrophic hypogonadism. Hhpogonadism is a high prevalence of low T concentrations in HIV-infected men 40 definition, Therefore, we suggest that clinicians not use the available case-finding questionnaires for detecting T deficiency in men receiving health care for unrelated reasons. Well-established reference ranges constitute the essential basis for identifying whether the circulating levels of a particular analyte, testosterone in this case, are normal or low.

Testosterone deficiency hypogonadism definition not imply simply a state of low testosterone productionbut rather to be testosterone deficient is to have low testosterone levels combined definihion symptoms or signs that are associated with low serum total testosterone henceforth referred to as 'low testosterone'. Based on these considerations, we recommend that clinicians obtain a urological consultation if a prostatic abnormality is detected on DRE. Lipid Profiles. The categorization of evidence strength is conceptually distinct from the quality of individual studies.

Evaluate formulation-specific adverse effects at each visit as per Practice guidelines hypogonadism definition 5. The relationship of endogenous T concentrations and coronary artery disease in cross-sectional and prospective cohort studies has been inconsistent We suggest that clinicians offer evaluation of prostate cancer risk beginning at age 40 in hypogonadal men who are being considered for testosterone therapy and are at high risk of prostate cancer e. Finally, a randomized trial of 76 men mean age Endocrine Society committees and members and the cosponsoring organization were invited to review and comment on preliminary drafts of the guideline.

Most studies of T therapy in young, hypogonadal men were open label and did not include a placebo group. In men with osteoporosis who are not considered to be at high risk for fracture, clinicians should repeat BMD measurements 1 to 2 years after initiating T therapy to determine the response to T and to ascertain whether the patient needs additional therapy with an approved osteoporosis drug. Therefore, clinicians should measure total testosterone concentrations on two separate mornings when the patient is fasting.

Vigen et al. If normalized, subsequent serial imaging can be performed defimition two to five years. Gianatti, E. Analyse LH and Practice guidelines hypogonadism definition serum levels to differentiate between primary and secondary forms of hypogonadism. This recommendation also places a high value on avoiding interventions with unclear outcomes. Observational trials show a correlation between restored physiological testosterone levels, muscle mass and strength measured as leg press strength and quadriceps muscle volume [ 51].

In men deemed to have secondary hypogonadism, additional diagnostic evaluations may be needed to exclude hyperprolactinemia, head trauma, iron overload syndromes, hypothalamic or pituitary tumors, practice guidelines hypogonadism other infiltrative or destructive hypothalamic—pituitary diseases, as well as genetic disorders associated with gonadotropin deficiency. Hematopoiesis shows closer correlation with calculated free testosterone in men than total testosterone. However, clinicians should only use the prostate cancer risk calculator for men 55 to 95 years old; furthermore, clinical experience with this tool is limited especially in men with hypogonadism and criteria for urological referral have not been established. As previously noted, screening and monitoring for prostate cancer entails some risk.

It is the opinion huidelines the Panel that testosterone therapy, with close monitoring to ensure appropriate dosing and safety surveillance, may be considered in these patients definition a three to six month waiting period. COI Disclosure. For example, outcomes of meta-analyses using RCTs alone are generally more robust than those that also include cohort studies. Normal sperm production depends on a functionally intact hypothalamic-pituitary-gonadal axis with normal secretion of pituitary LH and FSH to support intratesticular testosterone production and spermatogenesis. Based on these considerations, we recommend that clinicians obtain a urological consultation if a prostatic abnormality is detected on DRE. Mortality in testosterone treated men was

At the same time, many men with organic MH, who would be expected to benefit from testosterone treatment, continue to remain undiagnosed and untreated due to deficient basic and postgraduate medical training in sexual medicine. PLoS Genet.

All three statement types may be supported by any body of evidence strength grade.

In surveys of community-dwelling middle-aged and older men, low libido, erectile dysfunction, and less specific symptoms such as fatigue, irritability, depressed mood, poor concentration, reduced physical performance, and sleep disturbance are associated with low T concentrations 10 The guidelines should not be considered inclusive of all proper approaches or methods, or exclusive of others. Glenn R Cunningham. Additional signs in males include erectile dysfunction, muscle atrophy, gynecomastia and increased abdominal fat. Many older men harbor small foci of subclinical cancer in their prostate ; we do not know whether T replacement might cause these subclinical cancers to grow and become clinically overt. T concentrations may be affected by acute illness, nutritional deficiency, and by certain medications e. The baseline assessment of prostate cancer risk should consider risk factors, such as age, family history increased risk in men having a first-degree relative with prostate cancerrace increased risk in African Americansprior biopsy history, elevated PSA levels, and positive prostate examination results.

The task force also used consistent language and graphical descriptions of both the strength of a recommendation and the quality of evidence. A harmonized reference range for FT has not been established, so reference ranges may vary considerably depending on the specific equilibrium dialysis method or the algorithm used to calculate FT. Differences in age, geography, date of initial testing testosterone immunoassay testing was more commonly used beforecomorbid conditions, and baseline and therapeutic testosterone levels across studies introduce heterogeneity in the pooled population. Three others did stop testosterone in response to the PSA bounce, two of whom had negative prostate biopsies. This strategy places a relatively lower value on avoiding the burden and cost of tests with unknown yield. Considerable heterogeneity across trials, varying degrees of weight loss and disease severity, variable T regimens and treatment durations, and imprecision all limited the strength of inferences.
