Men’s Sexual Health & T1D as We Age: What Changes, Why It Happens, and What Helps

The Big Picture

Sexual changes are common with aging—and they’re more common and tend to appear earlier in men living with diabetes. Diabetes affects the small blood vessels, nerves, and hormones that all need to work together for sexual desire, arousal, and erections. The good news: there are many effective ways to improve sexual function and intimacy at any age.

What Can Change (And Why)

1) Erectile dysfunction (ED).
ED is the most frequently reported men’s sexual issue in diabetes. Compared with men without diabetes, ED is ~3.5× more common due to a mix of vascular changes (reduced nitric oxide and blood flow) and neuropathy (nerve damage), often compounded by blood pressure or cholesterol problems. ED can also be an early flag for cardiovascular disease, so it’s worth addressing. (ED and Diabetes: A Melting Pot of Circumstances and Treatments)

2) Autonomic + Peripheral Neuropathy.
Diabetic autonomic neuropathy affects the nerves that regulate sexual response and ejaculation; peripheral neuropathy can blunt genital sensation. Together they can cause ED and ejaculatory disorders (delayed ejaculation, retrograde ejaculation, or anejaculation). (Autonomic Neuropathy and Urologic Complications in Diabetes)

3) Hormonal Changes (Low Testosterone).
Men with diabetes are at higher risk of functional hypogonadism (low testosterone), which can reduce libido, energy, and erectile quality. Diagnosis requires symptoms plus low morning testosterone on repeat testing, with careful evaluation of causes and risks before any treatment. (Testosterone Therapy for Hypogonadism Guideline Resources)

4) Mood, Sleep, and Medications.
Depression, anxiety, poor sleep or obstructive sleep apnea (OSA), and certain medicines (some SSRIs, thiazide diuretics, non-selective beta-blockers, finasteride) can all worsen sexual function—each is more common in mid- to later-life and with diabetes. Treating these often improves sexual health. (Sexual Dysfunction, depression, and Marital Adjustment in Diabetic Male Patients)

What to Watch for and Discuss with Your Clinicians

• Screening is Now Recommended: The American Diabetes Association (ADA) 2025 Standards say men with diabetes or prediabetes should be screened for ED and evaluated for hypogonadism if symptomatic. A simple, respectful conversation opens the door to help. (Summary of Revisions: Standards of Care in Diabetes—2025)
• Ask About Autonomic Symptoms: Dizziness on standing, resting tachycardia, bladder symptoms, or changes in ejaculation can point to autonomic neuropathy and guide the work-up.

First Steps You Can Take (Often Surprisingly Effective)

• Optimize Cardiometabolic Health: Gentle, regular activity, nutrition that supports steady glucose, blood-pressure and lipid control, stopping smoking, and limiting alcohol all improve endothelial function and erections (and your heart). Even modest improvements can help.
• Sleep and Mood Tune-ups: Screen for OSA (snoring, pauses in breathing, unrefreshing sleep) and treat depression/anxiety—both show links to ED and quality of life. (Erectile Dysfunction and Obstructive Sleep Apnea: A Review)
• Medication Review: If ED began after a new prescription, ask whether a diabetes-safe alternative exists. (Never stop a medicine without medical guidance.) (Cleveland Clinic Journal of Medicine: What are Options for my Patients with Erectile Dysfunction who have an Unsatisfactory Response to PDE5 Inhibitors?)
• Practical Diabetes Tweaks for Intimacy: If hypos are a fear, consider timing insulin/boluses and meals to reduce risk, keep glucose tabs nearby, and use CGM alerts thoughtfully. (Your diabetes team can help personalize this.)

Evidence-Based Medical Options (What Works)

• Oral PDE5 Inhibitors (First-Line): Sildenafil, tadalafil, vardenafil, or avanafil are recommended first-line unless contraindicated. They’re effective in diabetes, though some men may need dose adjustments. Do not combine with nitrates (for chest pain) and use caution with certain alpha-blockers—review your meds with your clinician. Cardiology/Princeton IV guidance supports their cardiovascular safety profile for most men when used appropriately. (Erectile Dysfunction: AUA Guideline (PDF))
• Vacuum Erection Devices (VED): A non-drug option that can be used alone or with pills; particularly helpful when pills aren’t tolerated or are contraindicated. Modern reviews show good acceptance and effectiveness when taught correctly. (Oxford Academic: Vacuum Erectile Devices for Erectile Dysfunction: Recommendations from the 5th International Consultation on Sexual Medicine)
• Second-Line Therapies: If pills/VED aren’t enough, urologists can offer intraurethral alprostadil, intracavernosal injections (e.g., alprostadil or combination therapy), or low-intensity shockwave in selected cases; for durable results when other therapies fail, penile implants have high satisfaction rates. Shared decision-making matters—preferences and partner input count.
• Addressing Low Testosterone (When Present): If you have clear symptoms and repeatedly low morning testosterone, Endocrine Society guidelines outline when testosterone replacement therapy (TRT) may be appropriate and how to monitor for benefits and risks (hematocrit, prostate, lipids, cardiovascular risk). TRT is not an ED cure-all, but in true hypogonadism it can improve libido and response to ED treatments. (Endocrine Society: Testosterone Therapy for Hypogonadism Guideline Resources)
• Ejaculatory Problems (Retrograde, Delayed, Anejaculation): These are often due to autonomic neuropathy. Management ranges from medication adjustments and timing strategies to fertility-focused options when conception is the goal. A urologist familiar with diabetes can tailor therapy. (Ejaculatory Dysfunction in Men with Diabetes Mellitus)
• Sex Therapy and Pelvic Floor Therapy: When performance anxiety, relationship strain, or pelvic floor dysfunction contributes, AASECT-certified sex therapists and pelvic floor physical therapists can make a meaningful difference alongside medical care. (Adjunctive, but evidence-supported in comprehensive ED care.)

When to See a Specialist

• Any Persistent ED (≥3 months), problematic ejaculation, low libido with low energy, or distress about sexual function.
• New-Onset ED can coincide with cardiovascular risk—your clinician may check BP, lipids, A1c, and consider heart evaluation. (Springer Nature: Differences in the Prevalence of Erectile Dysfunction Between Novel Subgroups of Recent-Onset Diabetes)

A Simple Plan to Bring to Your Next Visit

1. “I’d like to talk about erections and intimacy—this matters to me.”
2. Ask for: basic labs (A1c, fasting lipids), morning total testosterone (repeat if low), medication review, depression/sleep screening, and discussion of PDE5 inhibitors (and contraindications). (Science Direct: Longitudinal Patterns of Occurrence and Remission of Erectile Dysfunction in Men With Type 1 Diabetes)
3. If pills aren’t enough or aren’t safe, discuss VED, injections, or referral to a urologist experienced with diabetes.

Bottom line

A satisfying sex life is possible at every age with T1D. If something’s changed—desire, erections, or ejaculation—you’re not alone and there are effective options. Speak up, get screened, fine-tune the basics (sleep, mood, meds, cardiometabolic health), and use treatments that fit your body and your preferences.
