Doc,
Why would you need to take a HairDX test to test DHT sensitivity to Propecia. Wouldn’t a PSA test tell you that? Propecia dropped my PSA around 66% so I know my DHT is definitely sensitive to the drug. On the other hand after a year on the medication I haven’t seen any positive effect. I would have expected a connection, but apparently there isn’t one. At least in my case.
That may be why you should consider the HairDX Finasteride Response test, because if it shows that you are not sensitive to Propecia, maybe conditions might be reasonable to consider Avodart (something I rarely prescribe). As you are not one of my patients and I have not examined you, I would not be in a position to assess your situation. Why is your PSA elevated? Do you have prostate cancer? Elevated PSA levels may indicate prostate cancer (or did I get the wrong message about your PSA)?
There is no connection between PSA and DHT other than that testosterone is produced by the testicles and then broken down by the body to make DHT.

Come on now, I’m sure that he believed that the solution would be at hand in 5 years or so. If a weather man predicted a sunny day tomorrow, and tomorrow came with heavy rain, would you call that unethical behavior? There are limits as to the predictability of the future. In our capitalistic society, the entrepreneur believes that his inventions will work, will take less time than it really takes to develop a marketable product, and he often puts his hard earned savings into that business. Not all businesses succeed, not all ideas work and when they do not, it is the entrepreneur that usually pays the price for it. I am sure that Dr. Washenik was humbled by his failure to predict the timeline for cloning correctly. I personally commend him and Aderans for their persistence in working on the problem.
I know very little about Merck’s patent for topical finasteride, although they did file 2 patents (one in 1993 and the other in 1995) in the general area of finasteride use on skin. Johnson and Johnson holds at least two patents for topical finasteride, so it does appear that this is a hot field and what differentiates one process from the other is something that I do not have the time to review. Does anyone with a bunch of time and interest care to go through these and create an itemized list?
