7x6andchg: I proffer this description found on the internet:
A triangular flap of skin is removed from the pubic hair area. This allows access to the root of the penis which is then dissected from the pubic bone. From the inside of his groin, that buried part of the penis is pushed down and sutured in place. Then the triangular flap of skin is sutured in place to cover the extension. When healing is complete, pubic hair will grow out of this flap on the shaft of his penis.
The patient stays in hospital for one day, off work for five days and absolutely no sex for at least three weeks. He will take medication to inhibit erections.
To reduce the chance of scar tissue contracting or the penis retreating upward, a special bandage that has weights incorporated in it must wrapped around the penis two weeks post operatively. The traction was continued and increased for 4-6 months.
Complications include infection, erectile dysfunction, (impotence) or depression. Average increase in penis length was 3.5 cm. (or just over an inch).

It does not answer the idea of stretching this ligament, but does corroborate our idea that cutting it would add length. Still waiting for a doctor....
