Blood inflow
Most ED treatments try to increase the blood that flows into the penis.

Pills, injections, and pumps increase blood flowing in. Xialla works on blood flowing out — venous leak — through the deep dorsal vein. The anchor is what keeps the ring at the base during sex.
Most ED treatments try to increase the blood that flows into the penis.
In many men the erection fades because blood leaves too fast. Studies put venous leak as the cause in 55% of ED.
A regular ring tries to compress the dorsal veins. It slides during sex, and blood keeps escaping.
The patented anchor keeps the ring from moving. Outflow slows, and the erection can hold.
Blood enters through the cavernosal arteries. When the penis is erect, the shaft tissue squeezes the deep dorsal vein and the venules, which slows blood leaving.
If outflow is faster than inflow, the erection weakens or is lost. Slow the outflow, and it can be maintained.
A conventional ring constricts those veins, then moves. Each shift pushes blood out. Xialla’s band attaches to an adhesive pad on the lower back and draws the ring back to the base, against the scrotum, so the compression stays where it was placed.
Outflow is minimized. The erection forms faster, holds firmer, and lasts longer while the device is worn.
