About
If patients achieve target testosterone levels, but do not feel that they have sufficient improvement in their symptoms, clinicians should question whether testosterone deficiency is the etiology of their symptoms. Clinicians should counsel patients on the association between low testosterone and the increased risk of cardiovascular events, as well as the ill-defined cardiovascular risks and benefits of testosterone therapy in the testosterone deficient patient. In the uncommon circumstance where men have prior available off-therapy testosterone laboratory data considered reliable (early morning testing, appropriate assay), clinicians may consider titrating testosterone therapy dosing to return patients to their 'baseline' total testosterone level. In the event that patients do not experience symptomatic relief after reaching the specified target testosterone levels or remain testosterone deficient in the setting of symptom/sign improvement, testosterone therapy should be stopped. Conversely, a population-based retrospective case-control study utilizing a UK clinical database of 19,215 patients with confirmed VTE showed that there was increased risk of VTE in the first 6 months of testosterone therapy. Prostate cancer patients on testosterone therapy should have their PSA levels monitored on the same schedule as men without testosterone deficiency; however, clinicians may choose to increase the frequency of testing.
In randomized, placebo-controlled trials involving testosterone therapy this has been a rarely reported adverse event. Clinicians should be aware that symptomatic gynecomastia or other breast symptoms are an uncommon side effect in men on testosterone therapy. Hypergonadotropic hypogonadism, which is not a contraindication to begin testosterone therapy, can result from a number of conditions, including congenital abnormalities (KS being the most common), iatrogenic causes (e.g., bilateral orchiectomy, testicular radiation, chemotherapy), testicular trauma, infection, or autoimmune damage. The validation studies for each questionnaire use a distinct total testosterone cut-off for defining low testosterone; however, total testosterone has been shown to correlate poorly with most questions.164, 165
It will present with signs and symptoms of androgen deficiency. It is important to understand hypogonadism before reviewing the cardiovascular trials leading to these FDA updates. The FDA has made three changes to the labeling of testosterone products in recent years. Additionally, pharmacists are in an accessible position within communities to answer patients’ questions regarding TRT efficacy and safety. These guidelines are only one element in the complex process of improving the health of America. As such, they cannot substitute the individual judgment brought to each clinical situation by the patient’s family physician.
To assess the patient’s risk of prostate cancer, a prostate-specific antigen (PSA) is recommended at baseline, in 3 to 6 months, and then annually. As shown in TABLE 2,4 LH and FSH levels are drawn once to determine primary or secondary origin. Therefore, one low reading may not be indicative of chronically low levels.
Low testosterone may not be the whole story behind your ED. TRT is also not advised to be used for treating those with low testosterone caused by aging. Guidelines from the Endocrine Society say you should not have TRT if you have prostate cancer or breast cancer. But there are risks, too. Guidelines cannot include evaluation of all data on emerging technologies or management, including those that are FDA-approved, which may immediately come to represent accepted clinical practices.
As an example, a total testosterone value of 250 ng/dL may be considered low based on the current guideline but be marked within the normal range by the laboratory. 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. Evidence strength refers to the body of evidence available for a particular question and includes not only individual study quality but consideration of study design, consistency of findings across studies, adequacy of sample sizes, and generalizability of samples, settings, and treatments for the purposes of the guideline. Of the outcomes included in the protocol of this systematic review, data were available on quality of life (QoL), sexual function, cardiovascular events, anemia, bone health, insulin resistance, cardiovascular risk factors, mood, cognitive function, body composition, and numerous adverse events. The explosion in the use of testosterone in the past decade is multifactorial in its etiology, including the increased use of direct-to-consumer advertising, which has resulted in greater patient knowledge and demand; relaxation of the indications for testosterone prescribing by clinicians; and the establishment of clinical care centers devoted to men's health, testosterone treatment, and anti-aging strategies. Testosterone therapy should not be commenced for a period of three to six months in patients with a history of a cardiovascular events. Patients should be informed that the evidence is inconclusive whether testosterone therapy improves cognitive function, measures of diabetes, energy, fatigue, lipid profiles, and quality of life measures.
