This is where things got interesting.
Most ED treatment is built on one idea: get more blood into the penis.
Pills do that by forcing the blood vessels open. They work for a few hours. Then they wear off. Then you take another one.
What that model ignores is where the nerve signal comes from in the first place.
An erection does not start in the penis. It starts in the brain, travels down through a specific set of nerves, and arrives at the smooth muscle tissue that has to relax before blood can enter.
Those nerves run alongside the prostate gland.
When the prostate enlarges, it pushes against that nerve pathway. The signal that leaves the brain arrives at the penis weakened, distorted, and incomplete. The smooth muscle does not get a clean instruction to relax. Blood flow is restricted not because the vessels are the problem, but because the message telling them to open never fully arrived.
Forcing vessels open with medication does not fix a degraded nerve signal.
It produces an erection the same way jumpstarting a car with a dead battery produces movement. It works temporarily. The underlying problem is still there.
The only way to restore natural function is to relieve the pressure on those nerves.
That means shrinking the prostate.
Plant sterols found in properly processed pumpkin seed oil have been shown in clinical research to reduce prostate tissue swelling. When the swelling reduces, the pressure on the nerve pathway lifts. The signal travels fully. Function returns without chemical override.
