Found this on webmd, a male's review of cabergoline (Dostinex). The cabergoline was given to reduce prolactin levels, which are also often raised due to Invega.
"Comment:
MRI discovered Pit tumor. Dr. Ask me if i had any prob. Yes, no sex drive for many years. They revealed Prolactin level was 1700mg? After hormone test. Prescribed Cabergoline .5 mg. Prolac dropped to 30mg almost immediately. I rediscovered what women were for. My penis actually grew back to where it should be, very proud of it now. My testicles are sore occasionally but it is a good sore i think they are filling back up( my feeling only) now that i actually think about sex i asked my primary for Viagra. I used 1/2 50mg tablet (expensive stuff) thought I was walking around with somebody elses erection. Damn that felt nice. Now I am looking for a woman to share my 18 year old penis with. My wife has her own sexual problems. So here I am with a new predicament, we are both 55 y.o."
