Factors Associated with Sex Hormones and Erectile Dysfunction in Male Taiwanese Participants with Obesity

Abstract

Introduction Obesity has been receiving an increasing amount of attention recently, but investigations regarding the potential impact of obesity, sexual behaviors, and sex hormones on erectile dysfunction (ED) in men have not completely clarified the association. Aim To identify the relationship between ED, sexual behavior, sexual satisfaction, sex hormones, and obesity in older adult males in Taiwan. Methods Data were obtained from a baseline survey of 476 older adult males (≧40 years old). Their demographic data, body mass index (BMI), sex hormones, sexual desire, sexual satisfaction, and ED status were assessed. Main Outcome Measures The International Index of Erectile Function-5 (IIEF-5), Sexual Desire Inventory (SDI), and Sexual Satisfaction Scale (SSS) were used to assess ED, sexual desire, and sexual satisfaction. Results In all, 476 men were available for analysis. The mean age of the sample was 51.34 ± 7.84 years (range 40 to 70 years). The IIEF total score had a mean of 19.44 ± 4.98; 264 (55.5%) subjects had ED, 250 (52.9%) were currently obese (BMI ≧27), and 297 (62.4%) had metabolic syndrome. The results showed an increased risk of ED among obese men and subjects with lower levels of sex hormones and lower sexual desire. Testosterone levels were lower in subjects with obesity (P < 0.001). Among the predictors of ED, obesity (odds ratio [OR] = 1.62, 95% CI = 1.07–2.44, P = 0.021), abnormal high sensitivity C-reactive protein (hs-CRP) (OR = 10.59, 95% CI = 4.70–23.87, P < 0.001), and lower serum full testosterone (OR = 3.27, 95% CI = 2.16–4.93, P < 0.001) were significantly independent factors. Conclusions This study supports the idea of a close relationship between low levels of sex hormones, sexual desire, sexual satisfaction, obesity, and ED, and also shows that low free testosterone and hs-CRP may predict ED, even in obese populations.

Sex Hormones Predict the Incidence of Erectile Dysfunction: From a Population-Based Prospective Cohort Study (FAMHES)

“…Our results were in accordance with our previous cross‐sectional study, in which FT and BT were found to be inversely related to worsening ED. Moreover, the associations between low FT, BT, and ED were also observed in other previous studies [17,32]. Interestingly, the Olmsted County study, a cross‐sectional community‐based study, provided an age‐related mechanism that suggested that age‐related decline of BT levels led to decreased sexual function by specific biologic pathway [10].…”

How predictable is the erectile function of patients with epilepsy?

“…Low levels of free testosterone have been associated with ED [27][28][29]. Contrary to our expectations, the free testosterone levels were not associated with IIEF scores after correcting for confounding factors.…”

Biopsychosocial Management of Female Sexual Dysfunction: A Pilot Study of Patient Perceptions From 2 Multi-Disciplinary Clinics

“…Only 6.8% of patients in this study had been assessed within a team-based model prior to presentation at SDSM or MCWHC. 2 , 15 The purpose of this study was to assess whether the multi-disciplinary model demonstrated benefits in the form of enhanced patient satisfaction. At a time when provider reimbursement is based on Hospital Consumer Assessment of Healthcare Providers and Systems scores, patient satisfaction becomes the leading metric for compensation.…”
