For the first time, we demonstrate a tissue-specific methylation pattern of SRD5A2 promoter in PFS patients.
For the first time, we demonstrate a tissue-specific methylation pattern of SRD5A2 promoter in PFS patients [which] could represent an important mechanism of neuroactive steroid levels and behavioral disturbances previously described in PFS… The SRD5A2 promoter was more frequently methylated in the CSF of PFS patients compared to controls (56.3 versus 7.7%).

FDA is concerned that use of finasteride by pediatric patients may pose long-term safety risks.
Finasteride inhibits Type II 5(alpha)-reductase, which metabolizes testosterone to the potent androgen 5(alpha)-dihydrotestosterone. FDA is concerned that use of finasteride by pediatric patients may pose long-term safety risks regarding growth, development and sexual function.

But if recent activity on the research and regulatory fronts are any indication—to say nothing of the surge in efforts by patients and their loved […]
July 20, 2019 Dear Friends: Phase III of the PFS Foundation-sponsored research at the University of Milano (UniMi), which was designed to “study whether epigenetic modifications occur in PFS patients,” has successfully demonstrated epigenetic modifications in PFS patients. Titled Altered methylation pattern of the SRD5A2 gene in cerebrospinal fluid of post-Finasteride patients, the pilot study […]
June 5, 2019 Dear Friends: PFS naysayers’ days may be numbered. According to new research in the world’s most influential dermatology journal, medical science is leaning further toward the conclusion that finasteride can cause sexual dysfunction in men taking a 1-mg dose for hair loss. The paper, titled Sexual dysfunction in men taking systemic dermatologic […]
