You can raise it, naturally ( your testosterone, that is...) and reduce estrogen:
1. Never eat Tofu.
2. Stop eating Chicken.
3. Do "prison Squats" and high intensity exercise.
4. Goto Youtube and search for "Raising Testosterone Naturally"... (the one by the 2 black guys is rated R.)
In my research I read about tofu (and soi milk) and high intensity exercise, not chicken though. I assume that's because what the producers inject the chicken with to make them fat (estrogen?). I don't eat or drink any soi products, but do eat chicken once or twice a week, and I do exercise almost daily but at my age and health condition I don't think I'm up to "high intensity" exercise. I try to do six days a week alternating about 45 minutes each day between strength training one day followed by aerobic (treadmill, brisk walking on an uphill incline, heart rate 80%) the next day.
Zinc helps, too.
I take zinc daily in the form of a mufti-vitamin (Centrum Silver). It supposedly provides 100% of the necessary amount according to the U.S. RDA.
I am overweight. My research provided confusing results on that. I read that being overweight can both be caused (or worsened) by low testosterone and can be (part of) the cause of it being low.

I guess what that is saying is that if you are gaining weight because of low testosterone, then you need to fight harder to keep that weight down or it will worsen like a snowball rolling downhill.
Alcohol reduces Testosterone.....
I do drink daily, mostly wine, and mostly with food, but I do drink too much (probably average 1 to 1.5 bottles of wine per day)... hard to tell exactly; that's the danger of buying wine in 5 liter boxes and being retired and bored so that I drink with both lunch and dinner (and the occasional in between snack). I rarely drink spirits nowadays and I only drink beer when I am out for lunch or dinner with a beer drinking friend, about once every 10 days. Also I try to balance my alcohol drinking with water drinking, meaning I drink at least as much, probably more, water every day than I do alcohol.
So I guess being overweight, eating chicken, and drinking may have contributed to my issue. I'm already in a constant fight with the weight issue with the exercise, but I just have too much time on my hands for eating and drinking which is counterproductive. I can stop or cut down on chicken consumption and try the Chinese herbal remedy mentioned above... guess I need to try to change my lifestyle and get tested again in six months. I was asking about therapy because I know a 69 year old here (up north) who is doing it and told me he felt very much younger and stronger since he started it. He drinks a lot of wine too, but is not overweight and is an avid exerciser, in fact, probably in better shape than any 69 year old I've ever known, yet his doctor put him on therapy (weekly shots I think).
