The reference website below I think is very good for those who have a health focus or concern. It even has a very positive section on Prostate Orgasm. The Aneros Helix and Helix Syn are praised as the ideal aids for prostate massaging and Progasm Ice is also reference. There may be other Aneroses mentioned. I am not sure if the caution about excessive Kegel exercises is correct but generally I found the site particularly supportive, encouraging and self empowering. Of course it does not have the same detail and found in the eight thousand Aneros Forum discussions!
It also notes diet and good old Saw Palmetto as the herb that stops the production of 5-alpha-reductase (the catalyst that transforms testosterone into dihydrotestosterone (!! whatever that is? I guess it enlarges the prostate)
I could not find anything that I felt was not really helpful. Of course apply only what is useful.
