oestradiol = female hormone - it can balance out the good effects of the testosterone a bit
My hubby has low testosterone and underactive thyroid, so he quite often mimics symptoms of depression, has no energy, no motivation, NO sex drive whatsoever, not much emotional support for me, in his own little world etc
Within a week of taking the tamoxifen, his energy levels shot up, he was happier, incredibly motivated, much more supportive of me, doing jobs around the house and feeling pleased with himself for doing them. It was like a great cloud had been lifted. Unfortunately his sex drive has never returned
We had a blood test after 2 weeks and his testosterone had shot up from something like 8 to 13
so it all co-incided with the change of mood / energy
Unfortunately he can't take those tablets permanently, so he's gradually slipped back down to how he was before. We need to see his specialist again to find out of the mTESE procedure can be done if necessary because if it can't or there's no point because he took out all the good tubules then we need to get on him testosterone replacement therapy. Can't do that until we're 100% sure we wont or can't get anymore sperm from him
