Cardiometabolic Risk and Female Sexuality-Part I. Risk Factors and Potential Pathophysiological Underpinnings for Female Vasculogenic Sexual Dysfunction Syndromes

Abstract

Introduction: Erectile dysfunction is recognized as an opportunity for preventing cardiovascular (CV) events, and assessing the impairment of penile vascular flow by Doppler ultrasound is an important tool to ascertain CV risk. Conversely, the role of genital vascular impairment in the pathophysiology of female sexual dysfunction (FSD) remains contentious.

Aim: To focus on the current scientific support for an association between CV risk factors and female sexual health in the 1st part of a 2-part review.

Methods: A thorough literature search of peer-reviewed publications on the associations between CV risk factors and FSD and their underlying mechanisms was performed using the PubMed database.

Main outcome measures: We present a summary of the evidence from clinical studies and discuss the possible mechanisms providing the pathophysiologic bases of vasculogenic FSD syndromes.

Results: The peripheral sexual response in women is a vascular-dependent event, and evidence suggests that cardiometabolic-related perturbations in endothelial function can determine vascular insufficiency in female genital tissues. Although epidemiologic and observational studies demonstrate that the prevalence of FSD is higher in women with diabetes mellitus, a cause-effect relation between these clinical conditions cannot be assumed. Evidence on the effect of obesity, metabolic syndrome, and polycystic ovary syndrome on sexual function in women is controversial. Data on the associations of dyslipidemia and hypertension with FSD are limited.

Conclusion: Common cardiometabolic alterations could affect vascular function in the female genital tract. Based on limited data, there is an association between CV risk factors and female sexual health in women; however, this association appears milder than in men. Maseroli E, Scavello I, Vignozzi L.
