Titled “A Preliminary, Hypothesis-Generating Investigation of the Post-Finasteride Syndrome: Description of the Phenotype, and Elucidation of the Hormonal, Genetic and Epigenetic Mechanisms,” the study is being led by Shalender Bhasin, M.D., Director of the Research Program in Men's Health: Aging and Metabolism at BWH.
The objective of this systematic investigation will be to determine whether there is a syndromic constellation of signs, symptoms and hormone levels that characterize PFS.
PFS has been reported to occur in men who have taken the prescription drug finasteride to treat hair loss (under the brand name Propecia and generics), or enlarged prostates (Proscar and generics).
Reported symptoms include loss of libido, erectile dysfunction, Peyronie's disease, penile shrinkage, gynecomastia, muscle atrophy, cognitive impairment, severely dry skin, and depression. 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.
Methods of the BWH study are as follow:
(1) Evaluate sexual, psychological and cognitive function
(2) Assess hormone levels and metabolic parameters
(3) Identify epigenetic interactions with the androgen receptor (AR) and gene expression of AR-dependent genes
(4) Perform magnetic resonance imaging of the brain in a group of subjects consisting of PFS patients, former asymptomatic users of finasteride for male pattern hair loss, and age matched controls
The PFS Foundation believes this study will:
Patient recruitment is now under way.
“This study promises to be an important step in our progress toward better understanding post-finasteride syndrome,” said PFS Foundation CEO Dr. John Santmann.
On April 11, 2012, the Food and Drug Administration ordered drug manufacturer Merck to revise the labeling on Propecia to reflect mounting evidence that it can cause persistent sexual dysfunction. Of the 421 Propecia-related sexual dysfunction cases reviewed by the FDA in its probe, 14 percent lasted longer than three months after patients quit the drug.

About the PFS Foundation
Headquartered in Somerset N.J., the Post-Finasteride Syndrome Foundation was established in July 2012 as a 501(c)(3) organization, with private grants from families in the U.S. and abroad. Tax-deductible financial donations to the nonprofit organization can be made via PFSFoundation.org, which also houses published research, research goals, and media reports about PFS.
