Evidence status: EstablishedLosing an Erection During Sex
Why do I lose my erection during sex?
An erection that starts but fades can be caused by anxiety or distraction, alcohol, medicines, hormonal problems, nerve changes or a blood-flow problem in which the penis cannot hold blood well enough (venous leak or cavernosal insufficiency). Symptoms alone cannot show which, so a urologist usually starts with history and examination and uses penile Doppler ultrasound in selected men.
Key fact: Penile Doppler ultrasound can assess blood flow into and out of the penis in selected men with erectile dysfunction. (European Association of Urology, 2026; page updated )

Key takeaways
- An erection that is achieved and then lost is a recognised ED pattern with several possible causes.
- Anxiety, alcohol and some medicines are common and treatable contributors.
- Suspected venous leak is assessed by a urologist, often with penile Doppler ultrasound.
Possible reasons an erection fades
Venous leak
The penis cannot trap blood effectively, so the erection starts and then fades.
Learn more →Blood-flow problems
Reduced arterial inflow can make erections less firm and harder to maintain.
Learn more →Anxiety and distraction
Worry about performance can interrupt an erection even when the physical mechanism is intact.
Alcohol and medicines
Alcohol and some antidepressants or blood-pressure medicines can affect erections.
Hormones and nerves
Low testosterone, diabetes or nerve injury can contribute.
Learn more →What helps you work out the cause
- Does it happen with every partner and situation, or only in some? Situational patterns can suggest a psychological component.
- Are morning or night-time erections firm? Firm spontaneous erections suggest the physical mechanism can work.
- Did it start after a new medicine, surgery, heavy drinking or a period of stress?
- Do tablets help at first and then fade? Tell the prescriber exactly how you use them.
Assessment and options
A urologist reviews history, medicines and risk factors, examines you and may arrange blood tests. Penile Doppler ultrasound can assess arterial inflow and venous leakage in selected men. Options depend on the cause and may include risk-factor control, optimised PDE5 tablets, vacuum devices, penile injections and, for severe ED, an implant. Shockwave and regenerative therapies have limited evidence in confirmed venous leak and are discussed only when appropriate.
Compare ED treatments
The most appropriate treatment depends on the underlying cause of ED.
| Treatment | Typical candidate | Invasiveness | Number of sessions | Recovery | Primary treatment concept | Clinical assessment required |
|---|---|---|---|---|---|---|
| P-Shot (PRP) | Selected men with organic ED after assessment | Minimally invasive (injection) | Protocol varies; confirmed at assessment | Usually short; instructions given by the clinician | Injected platelet-rich plasma, proposed to support tissue repair | Yes |
| Shockwave / EdSWT | Vasculogenic ED; some partial responders to tablets | Non-invasive (no injection) | Clinic protocol: 12 sessions over about 2 to 3 months | No downtime expected for most men; confirmed by the clinic | Low-intensity shockwaves, proposed to support blood-flow pathways | Yes |
| Stem Cell | Selected men when established options were unsuitable or ineffective | Minimally invasive; may involve cell collection | Individualised; explained at assessment | Depends on the procedure; confirmed by the clinic | Cell-based preparation, proposed to support tissue repair | Yes |
| Exosome | Men asking about an investigational option | Minimally invasive if offered | Not established; confirmed only if offered | Confirmed if offered | Cell-derived vesicles, proposed to support repair signalling | Yes |
| PDE5 medication (e.g. sildenafil, tadalafil) | Many men with ED, unless contraindicated (for example with nitrates) | Non-invasive (tablet) | Ongoing, as needed or daily depending on the medicine | None | Increases the blood-flow response to sexual stimulation | Yes (prescription, with a health check) |
| Penile injections (e.g. alprostadil) | Men for whom tablets are unsuitable or ineffective | Self-injection after training | As needed before sex | None | Medicine injected into the penis to produce an erection | Yes (training and dose setting) |
| Penile implant | Severe or refractory ED after other options | Surgical | One operation | Surgical recovery; instructions given by the surgeon | A device placed in the penis that allows an erection | Yes (surgical assessment) |

Frequently asked questions
Is losing an erection during sex a sign of venous leak?
It can be, but it is not specific. Anxiety, alcohol, medicines, hormonal problems and blood-flow problems can look similar, so a urologist needs to assess it.
Can anxiety make me lose my erection?
Yes. Performance anxiety and distraction can interrupt an erection, and a physical cause can coexist. Assessment helps separate them.
How is it diagnosed?
Through history and examination, blood tests when useful and, in selected men, penile Doppler ultrasound.
Can it be treated?
Often something helps, but the treatment depends on the cause and no outcome can be promised. A urologist can explain which options are realistic.
