So I have been on HRT of about a year- 81mg daily of androgel, which has worked good. Also hypthyroid for about 5 years, on levothyroxin .88 mcg. When i went on HRT I was having bad ED problems, endo got me going...gone...gaining muscle, morning wood,sex was fine. A couple months ago I noticed lack of morning wood,sex drive and muscle building still there, blood work shows levels good- upper 800's....(Im 46). But i began having some ED issues. I would start the performance and either fizzle out halfway through, or go forever and tire out before my Johnson did...lol. My endo gave me some Levitra samples, and they worked...But same results...i start out hard enough to cut diamonds but about 15 minutes in Im struggling to keep going. Only other thing I started taking on my own to reduce testicular shrinkage was 50mg clomid about 3 times a week. But I took this even when things were going well, since about 3 months in to HRT. It Helped, and increase ejaculate amount. Also, not to get too detailed but problem only occurs during sex, i can still wack it like I am 14 with no issues, which is even more frustrating. I was thinking prolactin? I was gonna try Cabergoline, wanna get some thoughts, or if anyone had this...endo said if levitra didnt work he would send me to a urologist and they might stick a needle in my rod...not happening...ouch....
