I had a very low T(96), my drive was pretty much zero. I started noticing it a few years back, but didn't attribute it to low T since I didn't have any other symptoms, except tired all the time which I thought was from working night shift. At the start of a new relationship his mind/body may have increased its own T for short time or tumor wasn't as bad as in past. I just started T injections and can see some improvement with drive etc, but now all of a sudden I have zero energy. Think estrogen level now is high :/
