Testosterone Physiology Testosterone levels peak ~ 20 yrs, then decline ~1%/yr. Normal T levels are regulated by hypothalamic-pituitary- testicular axis Dysfunction manifests as different forms of hypogonadism Dandona P, Rosenberg M. A practical guide to male hypogonadism in the primary care setting. Int J Clin Pract. 2010;64:

Biochemical Definition of Hypogonadism Hypogonadism refers to any state of reduced testicular function, impaired sperm production, and low T Agreement on two thresholds for total testosterone (TT): >350 ng/dL (normal) and <230 ng/dL (low) Borderline TT : 230 – 345 ng/dL Buvat J, Maggi M, Guay A, Torres LO. Standard Operating Procedures for Diagnosing and Treating Testosterone Deficiency in Men. Journal of Sexual Medicine. In press.

Types of Hypogonadism Primary: abnormalities at testicular level  Examples: cryptorchidism, mumps orchitis, genetic conditions Secondary: abnormalities at hypothalamus or pituitary  Examples: pituitary tumors, medications, systemic disease Mixed: defects at both levels  Examples: aging, alcohol abuse, chronic infections Dandona P, Rosenberg M. A practical guide to male hypogonadism in the primary care setting. Int J Clin Pract. 2010;64:

Clinical Definition of Hypogonadism Requires below-normal TT and signs/ symptoms MMAS, using this definition, found prevalence in general population ranging from 7% (ages 48-59) to 23% (ages 70-80) No evidence that prevalence differs between racial and ethnic groups Araujo AB, O’Donnell AB, Brambilla DJ, et al. Prevalence and Incidence of Androgen Deficiency in Middle- Aged and Older Men: Estimates from the Massachusetts Male Aging Study. J Clin Endocrinol Metab. 2004;89:

Nomenclature Terms used to describe primarily age-related, below-normal T-levels with associated clinical symptoms:  Androgen deficiency  Andropause  Age-related hypogonadism  Testosterone deficiency (TD) Testosterone deficiency (TD) describes patients family physicians are likely to encounter in daily practice

Expert Panel Recommendation TD does not always need to be treated first in patients with associated comorbidities. To the extent testosterone levels can be raised by successful treatment or resolution of comorbid conditions, these approaches should be attempted first.

TD and Cardiovascular Disease Recent observational studies suggest that lower T is associated with higher risk of CVD No randomized controlled trials of TRT and CVD Routine testosterone measurement is not recommended for men with cardiovascular disease unless they also have symptoms of TD Buvat J, Maggi M, Gooren L, et al. Endocrine Aspects of Male Sexual Dysfunctions. J Sex Med. 2010;7:

TD and Erectile Dysfunction ED is a common “portal” to T assessment Relationship between ED and TD often unclear TD usually only one element of ED in older patients ED may be caused by vascular or smooth muscle dysfunctions, which is why TRT is generally ineffective for treating ED There may be a beneficial synergy between TRT and phosphodiesterase inhibitors in men with both ED and TD Buvat J, Maggi M, Gooren L, et al. Endocrine Aspects of Male Sexual Dysfunctions. J Sex Med. 2010;7:

TD Screening Guidelines 2010 Endocrine Society Guidelines recommend against screening non-symptomatic patients for TD Testing reserved for men with signs/symptoms Serum TT levels should be taken in a.m. Positive findings must be repeated T levels should not be assessed during times of patient illness, malnutrition, or other physiologic stressors Buvat J, Maggi M, Guay A, Torres LO. Standard Operating Procedures for Diagnosing and Treating Testosterone Deficiency in Men. Journal of Sexual Medicine. In press.

TD Symptoms and Signs TD is a challenging diagnosis Some signs/symptoms are much more suggestive of TD than others Bhasin S, et al. J Clin Endocrinol Metab. 2010;95(6): Symptoms & Signs More Specific to TD Incomplete or delayed sexual development Reduced sexual desire (libido) and activity Decreased spontaneous erections Breast discomfort, gynecomastia Loss of axillary and pubic hair, reduced shaving Very small (<5 mL) or shrinking testes Inability to father children, low or zero sperm count Hot flushes, sweats

TD Symptoms and Signs TD is a challenging diagnosis Some signs/symptoms are much more suggestive of TD than others Bhasin S, et al. J Clin Endocrinol Metab. 2010;95(6): Symptoms & Signs Less Specific to TD Decreases energy, motivation, and initiative Feeling sad or blue, depressed mood, dysthymia Poor concentration and memory Sleep disturbance, increased sleepiness Mild anemia Reduced muscle bulk and strength Increased body fat, body mass index Diminished physical or work performance Height loss, low trauma fracture, low BMD

Expert Panel Recommendation Family physicians should probe for non- physiological causes of low libido by asking questions such as, “Are you still sexually attracted to your partner?” or “Are you comfortable with your sexuality?” Referral to therapy may be appropriate if non-medical factors are involved.

Prostate Cancer and Testosterone Recent analyses refute earlier positive associations between T levels and risk of prostate cancer Most observational studies found no correlation Case-control studies find correlations between PC and low T Low T also associated with high Gleason scores, more advanced stages, higher recurrence rates, and worse survival rates Herman LM, Miner MM, Quallich SA. Practicing Clinicians Exchange. 2010;1(2):1-8. Endogenous Hormones and Prostate Cancer Collaborative Group. J Natl Cancer Inst. 2008;100: Morgentaler A, Rhoden EL. Urology. 2006;68:1263–1267. Morgentaler A. Eur Urol. 2007;52:623–625.

Prostate Cancer and Testosterone T suppression can reduce prostate growth and symptoms in locally advanced and metastatic prostate cancer Explanation: PC may be very sensitive to changes in serum T at low concentrations but insensitive at higher concentrations Currently no conclusive evidence that TRT in testosterone-deficient men increases PC risk TRT may, however, stimulate growth of metastatic prostatic cancers Buvat J, Maggi M, Gooren L, et al. Endocrine Aspects of Male Sexual Dysfunctions. J Sex Med. 2010;7: Dandona P, Rosenberg M. A practical guide to male hypogonadism in the primary care setting. Int J Clin Pract. 2010;64:

Prostate Cancer and Testosterone International guidelines: hypogonadal men w/Hx of PC and no residual disease may be considered for TRT AUA suggests urological consult prior to TRT if:  PSA > 4 ng/mL  PSA > 3 ng/mL in high-risk men (i.e. African- Americans, men w/family history of PC)  PSA velocity change is 0.75 ng/mL or more in 1 yr. Carroll P, Coley C, McLeod D et al. Prostate-specific antigen best practice policy – part I: early detection and diagnosis of prostate cancer. Urology. 2001;57:217–224.

TRT Contraindications Metastatic prostate cancer Breast cancer Patient desire to maintain fertility Moderate-high risk of adverse outcomes:  Unevaluated prostate nodule or induration  PSA > 4ng/mL or > 3 ng/mL in high-risk men  Hematocrit >50%  Severe LUTS  Uncontrolled or poorly-controlled heart failure Bhasin S, et al. J Clin Endocrinol Metab. 2010;95(6):

TRT Goals Safe restoration of normal physiologic T levels Reduction or elimination of symptoms Target T levels vary—most authors suggest a mid-range value of ~500 ng/dL For T injections, ES recommends ng/dL at midpoint between injections Dose escalations beyond normal range are not recommended Bhasin S, et al. J Clin Endocrinol Metab. 2010;95(6): Dandona P, Rosenberg M. A practical guide to male hypogonadism in the primary care setting. Int J Clin Pract. 2010;64:

TRT and Therapeutic Lifestyle Changes T levels have a synergistic relationship with lifestyle issues such as obesity, lack of exercise, and diabetes T levels often rise after weight loss Important to address T-related health issues either prior to or concurrent with a trial of TRT Emerging evidence suggests TRT may have positive synergistic effect on therapeutic lifestyle changes Niskanen L, et al. Changes in sex hormone-binding globulin and testosterone during weight loss and weight maintenance in abdominally obese men with the metabolic syndrome. Diabetes Obes Metab. 2004;6: Heufelder AE, et al. Fifty-two-week treatment with diet and exercise plus transdermal testosterone reverses the metabolic syndrome and improves glycemic control in men with newly diagnosed type 2 diabetes and subnormal plasma testosterone. J Androl. 2009;30:

Expert Panel Recommendation Family physicians considering TRT for a patient should incorporate therapeutic lifestyle changes such as weight loss with exercise, healthy dietary choices, and avoidance of smoking, into the overall treatment plan.

TRT Formulations Available in US

Potential Adverse Effects of TRT AEs associated with all types of TRT:  Erythrocytosis  Acne and oily skin  Reduced sperm production and fertility Less common AEs:  Gynecomastia  Exacerbation of male pattern balding  Growth of breast cancer  Induction or worsening of obstructive sleep apnea Bhasin S, et al. J Clin Endocrinol Metab. 2010;95(6):

Monitoring Patients on TRT

Expert Panel Recommendation Initial treatment with TRT should be viewed as a trial of therapy, with continuation dependent on satisfactory response and an absence of adverse effects. Patients should be evaluated 3-6 months after treatment start. If symptoms have not improved, or if unacceptable adverse effects are apparent, treatment should be withdrawn. If symptoms have improved and therapy is well-tolerated, patients should be evaluated annually.

Patient-Centered Management of TD Suggestions for improving patient care: Ask patients about the non-medical aspects of their lives Provide culturally-specific educational materials written or produced at an appropriate reading level Consider adopting the “medical home” model of health care delivery Set small, easily-achievable goals for lifestyle changes Make follow-up calls

Expert Panel Recommendation Family physicians must take the time to clearly explain to patients the risks and benefits of TRT, help them set realistic expectations for symptom improvement, and talk to them about the psychological and emotional components of healthy sexual relationships.

Conclusions TD is a complex, multi-factorial disease state bi-directionally related to several common conditions Because signs and symptoms of TD may be non-specific a diagnosis of TD must be made cautiously Prior to (or concurrent with) a trial of TRT, family physicians should encourage therapeutic lifestyle changes Decisions about TRT must rest on good patient education about risks and benefits

Conclusions New TRT formulations and delivery systems may allow more accurate dosing and may reduce risk of adverse events Long-term, high-quality data documenting the benefits and risks of TRT are lacking Nonetheless, available knowledge and guidelines can allow providers to assess and treat TD with greater confidence
