PFS is a variable and potentially devastating condition, but its molecular mechanism(s) are currently unclear. The predispositions that cause a subset of men to develop PFS from as little as a single exposure to a 5-alpha reductase inhibitor remain unknown. Reported symptoms include (but are not limited to) loss of libido, erectile dysfunction, suicidal ideation, depression, anxiety, panic attacks, cognitive impairment, Peyronie’s disease, penile shrinkage, gynecomastia, muscle atrophy, metabolic changes, digestive problems, severely dry skin and tinnitus. The condition often has a life-altering impact on victims and their families, such as job loss and the breakup of marriages and romantic relationships, while also being linked to suicides.
Elucidation of the biological mechanisms of PFS is critical to the development of treatments for the many patients suffering. It is also essential for consumers to be adequately informed of the associated risks of 5-alpha reductase inhibitor products, as the syndrome remains unacknowledged by the pharmaceutical industries and regulatory systems across the globe.
A major study into PFS is ongoing at the Baylor College of Medicine. Titled “Genetic and Epigenetic Studies on Post-Finasteride Syndrome Patients”, the research is being led by Mohit Khera, M.D., M.B.A., M.P.H., Assistant Professor of Urology in the Scott Department of Urology and Director of the Laboratory for Andrology Research, McNair Medical Institute at BCM. The objective of the study is to determine why PFS patients develop sexual dysfunction. To this end it will:
- evaluate sexual and psychological function
- assess hormone levels
- measure penile hemodynamic and sensory parameters
- study androgen receptor genetics and gene expression
- determine gene expression patterns and profiles
Ongoing studies and the previously published research into PFS have been funded by the PFS Foundation through direct donations. If you or a loved one are suffering from PFS, we encourage you to donate to support further research initiatives into the condition.
