Überblick
A venous Leck — medically, veno-occlusive dysfunction — is one of the most common physical causes of erectile dysfunction. In a normal erection blood flows in through the arteries and the veins pinch shut to trap it, keeping the penis rigid. With a venous leak those veins don’t seal, so blood drains away as fast as it arrives.
The tell-tale sign is an erection that starts firm but won’t stay — often harder to hold lying down, or fading before or during sex. It’s frequently missed, because tablets like sildenafil often work poorly when the problem is a leak rather than weak inflow. The good news: it can be measured objectively, and treated at the cause.
Doppler ultrasound screening
A quick, painless scan that measures penile blood flow and detects a venous leak — and screens the prostate and for Peyronie’s plaques in the same visit.

- One-visit men’s-health screen
Diagnose — Doppler-Ultraschall
We don’t guess. A penile colour Doppler ultrasound is the standard, objective test for a venous leak. After a small vasodilator injection to produce an erection, we scan the penile vessels and measure how well blood flows in (peak systolic velocity) and how much drains out (end-diastolic velocity). A persistent end-diastolic velocity above roughly 5 cm/s in the rigid phase points to a venous leak.
The same scan doubles as a men’s-health screen — checking penile blood flow, Peyronie’s plaques (scar tissue that causes curvature), venous leakage and the prostate — so you leave with a clear, complete picture from one visit.
Treatment — Bocox
For veno-occlusive ED that doesn’t respond to tablets, MENHANCE offers Bocox — a small intracavernosal injection of botulinum toxin. By relaxing the smooth Muskel in the penile blood vessels it lowers vascular resistance and helps the veno-occlusive mechanism hold blood in, rather than letting it leak away.
The evidence: in randomised placebo-controlled trials and a systematic review, intracavernosal botulinum toxin significantly improved erectile-function scores and Doppler blood-flow measures in men with vascular ED, with response rates around 40–77% and a good safety profile (the main effect being mild, temporary injection-site discomfort). Ergebnisse usually peak within a few weeks and are not permanent, so treatment is repeated as needed.
Bocox for veno-occlusive ED is an emerging, mechanism-based option; your doctor will walk you through the current evidence and whether it fits your scan. Exact dosing and pricing are confirmed at your consultation.
