Sexual dysfunction is common in men and women with diabetes

Sexual dysfunction is common in men and women with diabetes, a 2020 narrative review by Italian researchers reports. About 5 out of 10 men with diabetes have erectile dysfunction in the pooled data it cites. Women's rates vary widely. Few studies have tested newer diabetes drugs for sexual effects.

Key Findings

  • In a meta-analysis of 145 studies (88,577 men), erectile dysfunction affected 52.5% (95% CI, 48.8 to 56.2) once adjusted for publication bias, 37.5% with type 1 and 66.3% with type 2 diabetes.
  • That meta-analysis linked diabetes to a 3.5-fold higher risk of erectile dysfunction than in healthy controls.
  • Among 9869 Italian men with diabetes, erectile dysfunction affected 26% with type 1 and 37% with type 2 diabetes. The gap shrank after adjusting for age.
  • Hypogonadism (testosterone deficiency) occurs in an estimated 20% to 64% of men with type 2 diabetes, depending on the population studied.
  • Female sexual dysfunction ranges from 18% to 71% in type 1 diabetes and from 12% to 88% in type 2 diabetes, according to the review.

Interpretation

The paper is a narrative review. The authors summarize existing studies and describe no systematic search. Prevalence and incidence figures come from observational studies and meta-analyses, so they describe association. Rates differ widely between studies. Evidence on newer diabetes drugs (DPP4 inhibitors, SGLT2 inhibitors, GLP-1 receptor agonists) and men's sexual function comes mainly from animal models and a few human studies. For women, the authors state that no studies have tested whether weight loss from these drugs improves sexual function. MSD Italia supported the work. The authors declare no conflict of interest.

RRM Context

Restorative reproductive medicine looks for root causes and evaluates both partners. The review describes a two-way relationship between low testosterone and type 2 diabetes, with increased body fat most probably the major player in the authors' view. The authors describe metformin as beneficial for male and female reproductive function. They name insulin and sulfonylureas as drugs whose effects on weight may impair gonadal and sexual function. The authors call women's sexual health in diabetes under-investigated.

Abstract

The association between diabetes mellitus (and its micro- and macro-vascular complications) and erectile dysfunction is widely known and the presence of hypogonadism may further complicate sexual dysfunction and quality of life, given the association between hypogonadism and reduced libido, ejaculatory disorders, and depressive symptoms. However, the recent introduction of novel antidiabetic agents with a wide range of mechanism of action may have a significant impact both on male and female sexuality directly (by inducing side effects as urinary tract infections) and indirectly (improving metabolic status and reducing diabetes complications behind sexual dysfunctions). To date only few papers are reporting the sexual effects of these treatments and, often, these are not comparable in their results. Conversely, female sexual dysfunctions are somehow under-investigated. Data on prevalence is heterogeneous and specific pathogenic mechanisms, as well as the burden of psychological factors, are still heatedly debated. The aim of this narrative review is to summarize current knowledge and stressing out the need to diagnose male and female sexual dysfunctions also in light of the impact of treatments with novel antidiabetic agents. This would highlight the still unmet needs for sexual care in a diabetes care setting and could represent an incentive for future discussions, as well as a required theoretical starting point for studies on this subject.
