Erectile Dysfunction Causes: Why a Pill Is Rarely the First Question

Quick answer

Erectile dysfunction causes fall into four groups, according to NIDDK: physical disease such as diabetes and vascular problems, medicines, emotional factors, and lifestyle habits such as inactivity, heavy drinking and smoking. NIDDK adds that ED may be a symptom of another health problem, so the cause deserves a clinician's look before any supplement.

The map01

What are the main causes of erectile dysfunction?

NIDDK sorts them into diseases, medicines, emotions and lifestyle (NIDDK, Erectile Dysfunction).

Causes named by NIDDK (NIDDK, Erectile Dysfunction)
GroupExamples
DiseasesDiabetes, kidney disease, multiple sclerosis, hardened arteries, high blood pressure, stroke
MedicinesSome antidepressants, blood pressure drugs, pain relievers
EmotionalStress, worry, mood
LifestyleInactivity, heavy drinking, smoking, drug use

A warning sign02

Can ED be an early sign of heart disease?

It can be a symptom of another health problem, NIDDK says, and vascular conditions are on its list of causes (NIDDK, Erectile Dysfunction).

That is why a visit matters. A clinician can check blood pressure, blood sugar and cholesterol, and review medicines. About 30 to 50 million US men have ED, and NIDDK says it is not a routine part of aging (NIDDK, Erectile Dysfunction).

Keep taking prescribed medicine

If you suspect a medicine is the cause, ask the prescriber. Do not stop a blood pressure or heart medicine on your own.

Pills03

Are prescription ED pills different from supplements?

Yes. Prescription tadalafil and sildenafil are drugs, and doctors screen for nitrates first (MedlinePlus, Tadalafil).

MedlinePlus says your doctor will probably tell you not to take tadalafil if you take nitrates (MedlinePlus, Tadalafil). Some "natural" male products have been found to hide these drugs, which is why hidden drugs in male enhancement pills matters.

On the label04

Does Protoflow treat erectile dysfunction?

No. The label names no condition, and no trial has tested the product (Protoflow bottle label).

Epimedium (250 mg a serving) is a traditional libido herb, but studies are needed to verify its effects (MSK, Epimedium). Muira puama has insufficient evidence for sexual problems (RxList, Muira Puama). Asian ginseng's benefit for ED may be trivial (MSK, Ginseng (Asian)).

  • Ask first if you take an ED medicine or a nitrate
  • Epimedium: avoid with heart disease (MSK, Epimedium)

FAQ05

ED cause questions

Can antidepressants cause erection problems?

NIDDK lists some antidepressants among medicines that can lead to ED (NIDDK, Erectile Dysfunction). Talk to the prescriber before changing anything.

Does cycling or sitting a lot cause ED?

Our sources do not say. NIDDK lists inactivity as a lifestyle factor, so regular movement is a reasonable discussion topic (NIDDK, Erectile Dysfunction).

Is ED a normal part of getting older?

NIDDK says it is not a routine part of aging, so it is worth raising with a clinician (NIDDK, Erectile Dysfunction).

Could anxiety alone explain ED?

Emotional factors are one of the four groups NIDDK names (NIDDK, Erectile Dysfunction). A clinician can sort physical from emotional causes.

Can quitting smoking help erections?

Smoking is on NIDDK's list of lifestyle causes (NIDDK, Erectile Dysfunction). Ask your clinician what to expect.
