Histrelin
"I currently have my 2nd Vantas Implant and am very discourged with what i believe are negative side effects. I had a Radical protetecomy in June '04,(nerve sparing) then went through 40 radiation treatments due to the fact my PSA continued to elevate. ( ever so slightly ) My Dr. recommended the implant. it has, in my opinion. dramatically decreased my sex drive and created a serious problem of erectile dysfunction, due to the fact that it reduces your level of testosterone dramatically."
