Achieving an erection is one challenge—maintaining it throughout intercourse is another. Losing firmness midway is a specific form of ED called "erectile maintenance disorder" and is extremely common. The cause is usually a combination of vascular and psychological factors.
Why Erections Fade Midway
Maintaining an erection requires a continuous inflow of blood while the outflow veins are compressed. If either fails, firmness is lost:
- Venous leak — blood exits the penis too quickly (most common cause)
- Performance anxiety — adrenaline constricts blood vessels
- Insufficient arousal — distraction or reduced stimulation
- PDE5 inhibitor wearing off — medication timing issue
- Low testosterone — reduces sexual drive mid-act

Solutions for Venous Leak ED
Venous leak is diagnosed via dynamic penile Doppler ultrasound. Treatment with Li-ESWT Shockwave Therapy strengthens vascular tone and reduces venous leakage over a 6-12 session course. Penile injections (alprostadil) provide immediate relief for severe cases.
Treatment by Cause:
- Venous leak → Shockwave therapy + PDE5 medication
- Performance anxiety → Counseling + low-dose daily PDE5i
- Low T → TRT restores baseline arousal
- Severe vascular ED → Penile implant (permanent solution)
