Due to low testosterone in my bloodwork, and a low libido caused primarily to just aging (I'm 39) my doctor put me on a weekly injection of testosterone. I noticed shortly after I started taking it that my erections weren't as firm, but I didn't think much of it. Now I'm 60 days into the testosterone treatment and I can't get hard at all. Not even a twitch down there. It's a strange feeling to have the urge and not the ability. I've never had issues with ED before but now it's like it's just dead down there. My Dr. perscribed me viagra until we can get some test results back to see where my hormones are at. Is it likely that the testosterone is causing the ED? (I read your body sometimes turns it into estrogeon)? Will the viagra work for me when I basically get virtually no reaction down there to any stimulation at all? My wife and I have a great sex life - the testosterone was supposed to help that but right now it's about to kill it. I need to be able to be with my wife and I'm wondering if the viagra will actually help. Even with heavy stimulation right now, I get almost nothing. Also - if anybody has experienced this is the answer a simple estrogeon blocker to get my function back to normal? I have noticed that I got an initial rush of libido on the testosterone which has since lowered back down.
I'm no expert, but I believe yours is not an uncommon problem when one is doing testosterone. It's such a delicate balance of hormones that indeed, sometimes the T number goes way up, but so does the Estrogen and the net result is what you're experiencing. It will take a doctor who really knows his/her stuff to get the balance right. In the meantime, the main thing is to remember, this isn't you - it's a side-effect of the hormone replacement and will get better as you get the "numbers" sorted out with your doctor. Make sure your wife understands this so neither of you stress about it or assume it's permanent or anything like that, because it's not - it's just a phase you're going through.
As to the Viagra - it may or may not, you just have to try it and see. Too much Estrogen can kill its effect, but you may not be at that place, so give it a try and don't panic if it doesn't work - remember, this is a temporary situation.
