5 The reality of LOH symptoms

6 Three less specific symptoms of LOH Osteoporosis Overweight Depression and: Mortality!

7 T is metabolized to 5alfaDHT and 17betaEstradiol

8 Low trauma fracture, low bone mineral Density 1.Osteoporosis in men 10 years later than in women 2.More hipfractures in men with low testosteron High costs because of hip- and lumbar spine fractures Meier C, Arch Int Med 2008;168;

11 The risks of a high BMI: 30kg/m 2 = Obese Cohort study :6502 men born in 1955 in Denmark Follow up :33 years Normal weight: 5407 men =83% Underweight : 353 men =5% Overweight : 639 men=10% Obese : 97 men=1,5% Schmidt M, BMJ Open 2013:3(4)

12 Results Danisch Study, Schmidt, BMJ Open 2013 % of DM-2, hypertension, myocardial infarction, venous tromboembolism or death before the age of 55 years Normal weight : 20 % Overweight : 31 % Obese men : 48%

14 Association Mortality with Overweight and Obesity Meta-analysis by K. Flegal, JAMA, 2013, 309, PubMed and EMBASE search articles, - 97 elegible : combining a sample size of: - 2,88 million individuals deaths

15 Association Mortality with Overweight and Obesity Flegal, K, JAMA 2013

16 Lower mortality in overweight and grade 1 obese men/women Possible explanations: -Earlier presentation of heavier patients -Greater likelihood of receiving optimal medical treatment -Benefits of higher metabolic reserves Flegal K, JAMA 2013 ; 309

17 Low Testosterone as a risk factor for CV-Mortality Meta-analysis by Corona G, Eur J of Endocr, 2011, 165, Medline search articles, - 70 elegible

18 Lower T as a risk factor for (cardiovascular)mortality Corona G, 2011

19 LOH and all-cause mortality in men with DM-2 Muraleedharan V, T Hugh Jones, Nottinghamshire, UK -6-year follow up -n=581 men with type 2 diabetes -Mortality rates compared between: TT 10,4 nmol/l : n=343: 9% TT 10,4 nmol/l : n=238: 17,2% Eur J Endocrin,

21 Figure 3 Multivariate-adjusted survival curves using Cox regression model for treated and untreated groups compared with those with normal testosterone. 64 with TRT: 9,3% Effect of TRT on mortality in 238 men with low T Mean duration of TRT: 41 months Hazard ratio:2,3 for decreased survival 340 normal TT: 9,1% 174 without TRT: 20,1% Muraleedharan V et al. Eur J Endocrinol 2013;169: European Society of Endocrinology

25 Overview of the literature by Traish J Sex Med 2014

26 Three less specific symptoms of LOH Osteoporosis Overweight Depression and: Mortality!

27 2-year incidence diagnosis depression ICD-9-CM Increased incidence of depression in hypogonadism Shores et al Arch Gen Psychiat 2004 N = 278 men > 45 years initially without depression Total T nmol / L

28 Symptomprävalenz % Depression Zitzmann et al. JCEM Overall Somer s d: p < T<8 T:8-10 T:10-12 T:12-15 T:15-20 T 20 Sextile Total T (nmol/l) n (patients) (Total n = 434)

29 The reality of LOH-symptoms Symptoms not very specific, but Symptoms necessary for the Diagnosis LOH Symptoms are relatively mild, insidious and difficult to recognize but Often bothersome, and frustrating because of an overall decrease of the quality of life (until death!)

30 Are symptom questionnaires of any help? ADAM questionnaire 2000 Good sensitivity AMS-questionnaire 2004 Low specificity NERI Hypogonadism screener 2011 ANDROTEST /70%

31 AMS questionnaire 17 questions 5 points each In total 85 points

32 Frequency distribution of complaints by AMS in a normal population vs patients before and after 12 weeks of TRT no/little mild moderate severe 10 0 standard population before therapy after therapy Moore C et al, Eur Urol 46:80-87(2004)

33 New Definition of LOH: EMAS, Wu,NEJM 2010 Syndromic association between Triad of sexual symptoms and Biochemical condition -Low libido -Reduced spontaneous erections -Reduced sex-related erections -Morning Total T < 11 nmol/l (<3.1ng/ml) -Free T < 222,2 pmol/l (<64 pg/ml)

34 So, are the symptoms real?? Answer: Yes, they are Are the symptoms specific for LOH? No, only for a triad of three sexual symptoms

35 Is this the End? Pieter Brueghel de Oude

36 Or like this? Mick Jagger, 70 years The End
