No diagnosis needed. Researchers never see your name.
PFS / PAS / PSSD Summit 2026
In April 2026, Dr. Kenneth Peters held the first medical conference on PFS, PAS and PSSD together. Doctors, researchers and patients were in the same room.
From evidence to treatment
- Seven studies at the University of Milan, led by Professor Roberto Melcangi. Two are already published.
- They map what finasteride and SSRIs change in the brain, the nerves and the gut.
- In rats, a substance the body already makes reversed some of the damage. The next step is a trial in people.
- The research is funded by people living with PFS and PSSD. Your donation helps pay for that next step.
