I’m not sure if this would be useful to anyone here, but I made a genetic test for determining how you may respond to finasteride due to your genetics. While some of this is focused on hair regrowth potential, there is also a part dedicated to potential long term side effects.
I used the data form this study build the test: Cauci S, Chiriacò G, Cecchin E, Toffoli G, Xodo S, Stinco G, Trombetta C. Androgen Receptor (AR) Gene (CAG)n and (GGN)n Length Polymorphisms and Symptoms in Young Males With Long-Lasting Adverse Effects After Finasteride Use Against Androgenic Alopecia. Sex Med. 2017 Mar;5(1):e61-e71.

Let me know if you have any questions, concerns or comments.
