Diabetes, obesity, and erectile dysfunction.
ABSTRACT Diabetes mellitus (DM) and obesity affect large parts of the population in the United States and around the world. These disorders are among the most common risk factors for erectile dysfunction (ED), because of their effects on the vasculature and the hormonal milieu.
This article reviews the current literature on the connection between DM, obesity, and ED.
Using the search terms erectile dysfunction, endothelial dysfunction, hypogonadism, diabetes, and obesity, a systematic review of the available literature in the PubMed database was conducted. Relevant English-language publications (to August 2008) were identified.
ED is highly prevalent in men with both DM and obesity, and may act as a harbinger for cardiovascular disease (CVD) in this high-risk population. In addition to male hypogonadism and macrovascular disease, endothelial dysfunction is central to the connection between the metabolic syndrome and ED. Conversely, improved glycemic control and weight loss have been found to improve erectile function.
ED is very prevalent in men with DM and obesity. It is increasingly being recognized as an early clinical indicator and motivator for patients with CVD. The role of pharmacologic ED treatments in improving endothelial function is currently being investigated.

ABSTRACT: The aim of this review was to provide current scenario linking obesity and male fertility. Obesity has been linked to male fertility because of lifestyle changes, internal hormonal environment alterations, and sperm genetic factors. A few studies assessing the impact of obesity on sperm genetic factor have been published, but they did not lead to a strong consensus. Our objective was to explore further the relationship between sperm genetic factor and obesity. There are emerging facts that obesity negatively affects male reproductive potential not only by reducing sperm quality, but in particular it alters the physical and molecular structure of germ cells in the testes and ultimately affects the maturity and function of sperm cells. Inhibition of microRNA in the male pronucleus of fertilized zygotes produces offspring of phenotypes of variable severity depending on miRNAs ratios. Hence, these RNAs have a role in the oocyte development during fertilization and in embryo development, fetal survival, and offspring phenotype. It has been reported that the miRNA profile is altered in spermatozoa of obese males, however, the impact of these changes in fertilization and embryo health remains as yet not known.Andrology 10/2014; 2(6).

ABSTRACT: To investigate the prevalence, correlates, attitude and treatment seeking behavior of erectile dysfunction (ED) in type 2 diabetes mellitus (T2DM) patients in the primary care setting, a multi-center cross-sectional survey using a structured anonymous self-administered questionnaire was performed in 10 general outpatient clinics. Of the 603 subjects (91% response rate), the prevalence of ED men, as defined by the International Index of Erectile Function, was 79.1%. Most subjects had mild ED (28.9%), followed by mild-to-moderate ED (27.9%), then moderate ED (13.4%) and severe ED (9%). Nearly 55% of those with ED did not consider themselves as having ED. Less than 10% of them had ever sought medical treatment, although 76.1% of them wished to receive management from doctor(s) should they be diagnosed with ED. They considered the most important management from doctors to be clinical assessment (41.7%), followed by management of potential underlying cause (37.8%), referral to specialist (27.5%), education (23.9%), prescription of phosphodiesterase type 5 inhibitors (16.9%) and referral to counseling service (6.7%). The prevalence of ED was strongly associated with subjects who thought they had ED (odds ratio (OR) = 90.49 (20.00-409.48, P< 0.001)) and were from the older age group (OR = 1.043 (1.011-1.076, P= 0.008)). In conclusion, ED is highly prevalent among T2DM men. The majority of them wanted management from doctors should they have ED, but only a minority would actually voice out the request. Screening of ED among T2DM men using structural questionnaire allowed the diagnosis of more than half of the ED cases, which otherwise would have gone undiagnosed.Asian Journal of Andrology 04/2014; 16(5):755-60.
