Thank you for choosing DoctorSpring.
This particular device marketed by X4 labs might NOT help you in correcting the penile curvature. Infact no devices are proven to be effective enough in correction of penile curvature. (limited evidence + potential harm)
On the contrary these devices can cause damage to penile muscle and blood vessels. This may lead on to erection problems. The device also is NOT FDA approved.
Penile curvature to an extend in normal in adults. Unless it is severe no treatment is needed.
Anyhow this device is not recommended.
Hope this helps
