I have a very high estrogen of 132 pg/ml (max for men is 42 pg/ml) and I'm a die hard stationary cyclist. There was one study at UCLA http://www.dailymail.co.uk/health/ar...en-levels.html that found serious cyclists have very high estrogen in their blood. It is hard to believe and no explanation has been discoverd, but I'm afraid to cycle anymore because I wonder if it has been causing my very high estrogen. Has any other male here with high estrogen here read about that UCLA finding before and wondered the same?
I wanted to give up cycling for a month and try treadmilling instead and check the estrogen levels at the end of it, but I'm finding it very difficult because my body is cycling-fit and not running-fit so my joints and muscles get sore first before I reach the peak aerobic limits of my heart and lungs.
