Erectile Dysfunction: An Underestimated Presentation in Patients with Diabetes Mellitus

Predictive factors of sexual dysfunction and quality of life among type 2 diabetes outpatients in southern Iran: a cross-sectional survey

OBJECTIVES

This study was conducted to determine the predictors of sexual dysfunction and quality of life (QOL) in patients with type 2 diabetes (T2D). Sexual dysfunction is a long-term consequence of diabetes that is widely ignored in personal management, even though it can have an adverse effect on QOL.

DESIGN

This research was designed as a cross-sectional study.

SETTING

12 diabetes centres and clinics in Shiraz, south of Iran.

PARTICIPANTS

390 male patients with T2D mellitus participated in this project. The inclusion criteria were being 30-65 years, having a history of diabetes of at least 1 year, having fasting blood sugar and glycosylated haemoglobin tests and being willing to participate in the study. Patients with medication treatment for mental disorders, a history of heart disease and renal failure were excluded.

PRIMARY OUTCOME MEASURES

QOL and erectile dysfunction (ED). The questionnaires were the Audit of Diabetes-Dependent QOL (ADDQOL) and the International Index of Erectile Function (IIEF-15). Data were reported using descriptive and analytical statistics methods.

RESULT

The participants' mean age was 48.35±9.27 years. The average weighted impact (AWI) score of ADDQOL for the participants was -3.01, indicating the negative influence of diabetes on their QOL. The mean value of the total score of sexual dysfunction was 42.79±22.75, and the rates of mild, mild to moderate, moderate and severe ED were 19%, 17.7%, 17.2% and 24.6%, respectively. Sexual dysfunction was significantly related to age (OR=1.06; 95% CI: 1.02 to 1.09), diabetes duration (OR=1.04, 95% CI: 1.01 to 1.07), HbA1c (OR=1.45, 95% CI: 1.07 to 1.95), BMI (OR=1.10, 95% CI: 1.03 to 1.16), marital status (married: OR=2.30, 95% CI: 1.40 to 3.77), without diabetes complication (OR=0.17, 95% CI: 0.08 to 0.31) and insulin therapy (OR=2.86, 95% CI: 1.67 to 4.92). ADDQOL was significantly related to age (OR=1.049), HbA1c (OR=2.192), marital status (married: OR=2.089), educational level (high school certificate: OR=0.337, university degree: OR=0.295), diabetes complication (no complication: OR=0.372) and insulin therapy (OR=3.82). AWI was correlated with the total score of IIEF-15 (r=0.78, p value <0.001).

CONCLUSION

To improve the QOL of diabetic patients, it is suggested that all the predictors of sexual dysfunction, such as glycaemic control, obesity, diabetes complications and duration, should be considered in diabetic management guidelines.

Association of Sexual Health and Mental Health in Erectile Dysfunction: Expert Opinion From the Indian Context

Erectile dysfunction (ED) is a common condition in men, driven by a complex interplay of organic, relational, and psychological factors, necessitating an integrated treatment approach. Psychological factors, such as anxiety, depression, and stress, are significant contributors to erectile problems. Erectile dysfunction can have severe psychological consequences, including feelings of emasculation, humiliation, reduced self-confidence, isolation, loneliness, and a decline in overall well-being. A national advisory board comprising 12 experts from India, including 9 urologists and 3 psychiatrists, convened to discuss a multidisciplinary approach to the treatment of ED. Using a modified Delphi method and literature review, the 34 panels developed evidence-based insights. Experts highlighted the importance of thorough assessments of sexual dysfunction in patients. Given the frequent comorbidity of mental health issues with ED, physicians should proactively explore patients' sexual and mental health. Creating a secure and welcoming environment is crucial for these assessments. Physicians should gather detailed information on psychological symptoms, stressors, relationship dynamics, cognitive style, and distractions. Experts highlighted the importance of thorough diagnostic assessments and recommended a multidisciplinary approach integrating pharmacological interventions (e.g., phosphodiesterase-5 inhibitors) with psychometric therapy, tailored to the age, existing comorbidities, and underlying causes of ED. A balanced, interdisciplinary approach incorporating psychosexual therapy, lifestyle modifications, and advanced therapies is crucial for the holistic management of ED. Key consensus recommendations also emphasized fostering open communication between patients and healthcare providers, routine mental health screenings in patients with ED, and early referrals to specialists when necessary. Clinicians should actively involve mental health professionals in the management of ED and prioritize individualized treatment strategies tailored to each patient's needs. This multifactorial condition requires coordinated efforts to address both organic and psychogenic causes, restore patients' quality of life, and promote open communication. By proactively engaging with patients, addressing their concerns, and facilitating referrals as needed, clinicians can significantly improve outcomes for patients with ED.

Sexual dysfunction, depression, and marital adjustment in diabetic male patients

Background

Type 2 diabetes affects 10.5% of adults globally, with sexual dysfunction being one of the complications, of which erectile dysfunction is the most commonly reported one with the prevalence ranging from 35% to 90%. There are a few studies exploring links between sexual dysfunction, depressive symptoms, and marital satisfaction, which is the reason we undertook the study.

Aim

To study the prevalence of sexual dysfunction, depressive symptoms, and marital satisfaction in male patients with diabetes and correlation between the three parameters.

Methods

A total of 120 male patients with type 2 diabetes were assessed for sexual dysfunction using ICD-10 criteria and International Index of Erectile Function, depressive symptoms using Beck Depression Inventory, and marital satisfaction using Dyadic Adjustment Scale (DAS).

Results

The mean age of patients at diagnosis of diabetes was 42.32 ± 7.48 years, and the mean duration of diabetes was 7.35 ± 3.76 years. Mean HbA1c was 9.05 ± 2.25% with only 22 patients having good glycemic control. Eight-eight patients reported sexual dysfunction with lack of genital response, premature ejaculation, and orgasmic dysfunction being common. Thirty-two patients had depressive symptoms, with borderline clinical depressive symptoms and moderate depressive symptoms in 14 patients each. Marital satisfaction was affected with the total mean DAS score being 93.95 ± 18.34. There was a negative correlation seen between sexual function and depressive symptoms and also between sexual function and increasing age, with a positive correlation seen between sexual function and marital satisfaction. Poor glycemic control was significantly associated with clinically diagnosed erectile and orgasmic dysfunction.

Conclusions

Sexual dysfunctions, depressive symptoms, and marital distress are highly prevalent in patients with type 2 diabetes, warranting timely detection and management. The three parameters are significantly correlated with each other, and poor glycemic control is significantly associated with sexual dysfunction. Psychiatric liaison would improve outcomes.

Research Advances in Stem Cell Therapy for Erectile Dysfunction

Erectile dysfunction (ED) is a common clinical condition that mainly affects men aged over 40 years. Various causes contribute to the progression of ED, including pelvic nerve injury, diabetes, metabolic syndrome, age, Peyronie's disease, smoking, and psychological disorders. Current treatments for ED are limited to symptom relief and do not address the root cause. Stem cells, with their powerful ability to proliferate and differentiate, are a promising approach for the treatment of male ED and are gradually gaining widespread attention. Current uses for treating ED have been studied primarily in experimental animals, with most studies observing improvements in erectile quality as well as improvements in erectile tissue. However, research on stem cell therapy for human ED is still limited. This article summarizes the recent literature on basic stem cell research on ED, including cavernous nerve injury, aging, diabetes, and sclerosing penile disease, and describes mechanisms of action and therapeutic effects of various stem cell therapies in experimental animals. Stem cells are also believed to interact with host tissue in a paracrine manner, and improved function can be supported through both implantation and paracrine factors. To date, stem cells have shown some preliminary promising results in animal and human models of ED.

Stem cell therapy and diabetic erectile dysfunction: A critical review

Erectile dysfunction (ED) has been identified as one of the most frequent chronic complications of diabetes mellitus (DM). The prevalence of ED is estimated to be about 67.4% in all DM cases worldwide. The pathophysiological process leading to ED involves endothelial, neurological, hormonal, and psychological factors. In DM, endothelial and neurological factors play a crucial role. Damages in the blood vessels and erectile tissue due to insulin resistance are the hallmark of ED in DM. The current treatments for ED include phosphodiesterase-5 inhibitors and penile prosthesis surgery. However, these treatments are limited in terms of just relieving the symptoms, but not resolving the cause of the problem. The use of stem cells for treating ED is currently being studied mostly in experimental animals. The stem cells used are derived from adipose tissue, bone, or human urine. Most of the studies observed an improvement in erectile quality in the experimental animals as well as an improvement in erectile tissue. However, research on stem cell therapy for ED in humans remains to be limited. Nevertheless, significant findings from studies using animal models indicate a potential use of stem cells in the treatment of ED.

Benefits of erectile function recovery programs after radical prostatectomy (Review)

Radical prostatectomy is one of the most frequent therapeutic options used for the management of patients diagnosed with prostate cancer. Normal erectile function after radical prostatectomy is a great problem for numerous patients and a real challenge for urologists worldwide. The advancements that have been made over the years in terms of minimally invasive surgery, as well as in terms of surgical techniques, have reduced the incidence of erectile dysfunction, but even so, its rate remains high and the post-operative recovery of erectile function is a long and costly process. Phosphodiesterase 5 inhibitors have provided excellent results and have become the first-line treatment for these patients, followed by intracavernous injections with alprostadil. Several studies have underlined the impact of phosphodiesterase 5 inhibitors in terms of preventing the fibrotic changes that are responsible for the irreversible erectile dysfunction. The general opinion is that an erectile function recovery process should be started as soon as possible after surgery to prevent the negative effects of neuropraxia.

Penile Doppler ultrasonography and elastography evaluation in patients with erectile dysfunction

Purpose

To evaluate the relationship between erection grade, erectile function score, Doppler ultrasonography (US) indexes, and elasticity score (ES) according to Doppler US diagnosis in patients with erectile dysfunction (ED).

Material and methods

Real-time strain type penile elastography was performed during penile Doppler US examination for 88 patients with ED. The diagnosis according to Doppler US was determined. Erection score according to the Erection Hardness Grading Scale was evaluated. A scoring for erectile function was performed with the International Index of Erectile Function (IIEF-5), and the Sexual Health Inventory for Men (SHIM) was defined. The relationships, according to Doppler diagnosis, of ES, IIEF-5 score, SHIM scale, and erection score were evaluated.

Results

Among the patients, 50 (57%) had abnormal penile Doppler US findings. According to Doppler US findings, patients were classified as normal (n = 38), borderline for arterial insufficiency (n = 4), arterial insufficiency (n = 5), and venous insufficiency (n = 41). The lowest erection hardness grades and IIEF-5 scores were detected in patients with arterial failure. When compared to the normal group, in terms of ES, the arterial failure borderline group and venous failure group had lower scores, and the arterial failure group had a higher score. However, the only significant difference was obtained in the left cavernous body of the venous failure group.

Conclusions

Sonoelastography seems to add additional value for determination of stiffness of the penile cavernous body in routine evaluation of ED.
