Review I used Prostasol for 3 months and lowered my PSA from 16% down to 0.8%...I did suffer from tender nipples..reduced libido and finally in the 4 th month suffered a mini stroke.. I then read a Danish Medical study wwww.dkma.dk/prostasol..this group claimed the product contains synthetic Oestrogen and possible risks are strokes....I've since had every test to find an alternative cause and it was found I have aperforation between my left and right ventricle in my heart..I have a PFO operation in two weeks to seal the "hole"..My Pas is now up to 8.3% and want to know if progestreone may be more reliable hormone to control my elevated PSA as the Oestrogen is a risk as women have found..Best wishes to all my fellow PCa survivors Yanni Australia
