Erectile and Clitoral Dysfunction as Harbingers of Cardiovascular Disease: A Perspective
ED may flag cardiovascular disease years before symptoms — the evidence for women lags far behind

Summary
This perspective argues that vasculogenic erectile dysfunction in men and female sexual arousal disorder (FSAD) in women should be treated as early clinical signals of systemic cardiovascular disease, not merely quality-of-life problems. In men, the authors describe the evidence as robust: ED can precede coronary artery disease, stroke, and CV mortality by several years, creating a window for earlier risk-factor intervention. For women, a meta-analysis cited in the paper found approximately 1.5-fold increased odds of female sexual dysfunction (FSD) in those with CVD — but the authors themselves acknowledge this evidence is less mature, more heterogeneous, and lacks prospective longitudinal data linking objective genital vascular measures to hard cardiovascular outcomes.
Claims
Vasculogenic ED in men is an established early marker of coronary artery disease and is associated with increased stroke and CV mortality risk
The time lag between ED onset and clinical CAD provides a clinically actionable interval — described as "several years"
A cited meta-analysis found ~1.5-fold increased odds of FSD in women with CVD
Clitoral engorgement relies on the same vascular mechanisms as penile erection, meaning vascular insufficiency may manifest as FSAD before overt CVD
Antihypertensives, antidepressants, antipsychotics, diabetes, obesity, and depression all independently affect both sexual function and CV risk, complicating causal inference
The perimenopause period is identified as a potential window for strategic cardiovascular intervention in women
Emerging evidence links periodontitis to organic sexual dysfunction (mentioned in conclusions but not developed in the provided text)
Study Quality
This is a perspective piece, not a systematic review or meta-analysis. There is no formal literature search methodology, no PRISMA flowchart, no inclusion/exclusion criteria, and no quantitative synthesis. The authors draw selectively from the literature — including, by their own admission, "seminal studies from earlier decades for historical context." That framing is reasonable for a perspective, but it means the reader has no way to assess how representative the cited evidence is.
The authors deserve credit for being unusually candid about methodological limitations: they explicitly note that heterogeneity in how SD is defined (IIEF-derived scores vs. single questions in men; FSFI vs. other instruments in women) inflates cross-study variability and limits effect size comparisons. They also acknowledge that residual confounding from medications, depression, and multimorbidity could both exaggerate and obscure the true association depending on how carefully these factors are controlled. That level of self-critique is rare in a perspective piece and materially improves its credibility.
Red Flags
No systematic methodology: Literature selection is narrative and selective. There is no way to assess publication bias or whether contradictory evidence was excluded.
Uneven evidence base treated symmetrically: The men's and women's sections carry the same rhetorical weight in the conclusions ("clinicians should collaborate to incorporate sexual history"), but the underlying evidence differs dramatically in quality and quantity. The paper acknowledges this gap in text but then issues unified clinical recommendations anyway.
Recommendation language in a journal piece: The abstract states the perspective "endorses that clinicians should incorporate genital vasculogenic SD into CV risk stratification." This is advocacy, not findings. Science journalism notes the distinction.
Causality not established for women: The authors state FSAD should be viewed as "a risk-associated clinical signal rather than a proven predictive marker" — but this important qualification is buried in the conclusions after sections that imply equivalence with the male evidence.
Periodontitis claim drops in without support: The connection between periodontitis and organic SD is introduced in the final paragraph of the conclusions without any preceding discussion or citation in the provided text.
Funding includes advocacy organizations: SMSNA and ISSWSH are professional societies with a stake in elevating sexual medicine within cardiovascular care. Not disqualifying, but worth noting.
Strengths
Multi-disciplinary author group spanning cardiovascular pharmacology, biomedical engineering, and clinical urology
Unusually honest methodological limitations section that identifies specific confounders (medications, depression, definitional heterogeneity) that most reviews handwave past
Correctly distinguishes vasculogenic from psychogenic ED as mechanistically distinct in the context of CV risk
Raises a legitimate equity issue: women's sexual health has been historically under-represented in cardiovascular research, and clitoral vascular physiology is genuinely analogous to penile vascular physiology
No declared conflicts of interest; NIH and DoD funding adds independence
Verdict
The men's half of this paper summarizes a well-established association with reasonable nuance. The women's half is honest about being underdeveloped but still pushes for clinical implementation before the evidence warrants it. As a perspective piece, it cannot be faulted for lacking primary data — that's not what perspectives do. What it can be faulted for is issuing symmetric clinical recommendations ("multidisciplinary care is warranted") when the underlying evidence is anything but symmetric. Read it for the men's evidence synthesis and the unusually candid limitations section. Treat the women's conclusions as a research agenda, not an established clinical signal.
