1 Erectile dysfunction

2 Good Erectile Function

3 Having good Erections => crucial for all men Because erections & the coitus they allow major pleasure brings self-confidence confirms his state of being a full worthy male

4 Comparison of 2 circumcised human penises, erect (on left) & flaccid (on right).

5 Consensus conference: all men 25 years old & older regardless of sexual dysfunction complaints => should be asked about Erectile Dysfunction RESULTS: Erectile dysfunction = common = early manifestation of atherosclerosis & a precursor to systemic vascular disease. Endothelial dysfn = etiologic factor linking ED & cardiovascular disease CCL: The recognition of ED as an early sign of systemic cardiovascular disease offers an opportunity for prevention, partc. in high-risk & underserved minority populations. The algorithm stipulates that All men 25 years old & older regardless of sexual dysfunction complaints should be asked about Erectiel Dysfunction The presence of ED => should prompt an aggressive assessment for cardiovascular risk & occult systemic vascular disease Billups KL, Bank AJ, Padma-Nathan H, Katz S, Williams R. Erectile dysfunction is a marker for cardiovascular disease: results of theminority health institute expert advisory panel. : J Sex Med Jan;2(1):40-50; discussion The Epicenter for Sexual Health & Medicine, University of Minnesota School ofmedicine, Minneapolis, USA. klbillups@earthlink.net

7 Normal erection Erectile dysfunction

9 Erectile dysfunction = the inability to achieve &/or maintain an erection sufficient to permit satisfactory sexual intercourse Most cases of erectile dysfunction have a vascular etiology &, in patients with known cardiovascular disease, the degree of erectile dysfunction correlates with severity of that disease. In addition, cardiovascular disease and erectile dysfunction share the same risk factors for atherosclerosis & have a common pathophysiology (endothelial dysfunction); thus, erectile dysfunction appears asan early and sentinel symptom in patients with occult vascular disease, of the coronary or carotid arteries Sekoranja L, Bianchi-Demicheli F, Gaspoz JM, Mach F. [Erectile dysfunction: a potential useful marker for cardiovascular disease] Rev Med Suisse Mar 22;2(58):774-6, 778. Departement de psychiatrie, HUG, Geneve. lucka.sekoranja@hcuge.ch

10 Having no good Erections (Erectile dysfunction) => dramatic for all men A man who has no good erections anymore feels this as: major depersonalization major loss of malehood major loss of self-worth = beginning of a process that will cause a premature death

12 Aging & BMI => erectile dysfunction Erectile dysfunction Increased age (% of men) Increase in Erectile dysfn risk by 8.2% per year Increase in Erectile dysfn risk by 7.6% per kg/m² BMI. Higher BMI n = 675 workers (age range 45 to 60 yrs old) 5 45 y +3 50y y y kg/m² kg/m² kg/m² kg/m² +15 kg/m² Figure: An increase in erectile dysfunction risk was observed by 8.2% per year and by 7.6% per kg/m BMI.

13 Statin Therapy => Erectile dysfunction Mean International Index of Erectile Function (IIEF) score (range 0-25) n = 93 men Prior to statin therapy 21 After 6 months of statin therapy - 69 % Figure: Statin therapy reduced the IIEF score. Differences in dose, relative efficacy or relative lipophilicity of statin prescribed showed no correlation with change in IIEF score.

Int J Clin Pract Feb;60(2):141-5 St. Thomas' Hospital, London, UK 6.5 p < % experienced new onset erectile dysfunction Erectile dysfunction following statin therapy is more likely to occur in patients with severe endothelial dysfunction due toage, smoking and diabetes After 6 months of statin therapy, correlations were observed between lower IIEF scores (r = 0.62; p < 0.001) and age and diabetes and weakly with smoking.

14 Hormone Deficiencies That can cause Erectile Dysfunction

15 Testosterone & DHT Deficiencies can cause Erectile Dysfunction

16 DHEAs in men + aging male symptoms & sexual dysfn SUBJECTS: n = 348 patients The patients + total the Aging Male Symptoms (AMS) score of 29 => aging male symptoms the patients + an International Index of Erectile Function IIEF score < than 26 => sexual dysfunction. RESULTS: sign. serum DHEA-S & sign. E2 in the men + aging male symptoms sign. the DHEA-S & free testosterone in the men + sexual dysfunction Serum DHEA-S & free testosterone & age correlated sign. + the IIEF scores. The total AMS score correlated sign. only with age. serum total testosterone, FT, & DHEA-S levels correlated sign. with the andrologic symptoms of AMS the serum E2 correlated + psychological symptoms of AMS. CONCLUSIONS: DHEA-S & E2 might play someimportant roles in the symptoms of aging men. Basar MM, Aydin G, Mert HC, Keles I, Caglayan O, Orkun S, Batislam E.
