I can tell you for a fact that if you have low testosterone that can sometimes result in a low estradiol level (the opposite of what some people find) as testosterone is the fuel that fires estradiol, estradiol being a metabolite of testosterone (estradiol is the most potent estrogen and the one commonly measured and you can take it to be interchangeable for the word estrogen).
It is very common for men with hypogonadism to develop osteoporosis as a result of long term low testosterone.
Your testosterone level is fairly low, but all you have had measured from what you have told me is total testosterone in the blood.
A better picture could and should be elucidated by a more complete assesment of your endocrine system.
You should have
LH
FSH
Free Testosterone if not possible SHBG should be tested.
Estradiol
Prolactin
If possible dihydrotestosterone
The crucial factor is the level of free testosterone that is available for your body, if you cannot obtain such a test an estimate can be obtained by looking at total testosterone and a protein that binds testosterone called SHBG- Calculated Testosterone (CT).
Certainly your situation could very well require treatment.
There are differing forms of treatment for low testosterone which I am sure you will be aware of. There are the gels, differing types of injections, implanted pellets and tablets. It is very much a case of different strokes for different folks with something that works for some not working for others and vice versa.
Your gynecomastia is very unlikely to improve as a result of testosterone replacement therapy (TRT) given how long you have had the gynecomastia (it becomes fibrous after a couple of years and less responsive to medications). So if you want rid of the gynecomastia you will almost certainly require surgery.
The TRT could increase any existing gynecomastia and in fact could see it return post surgery- that is a potential hazard.
What a good endocrinologist would need to do is start you on TRT and monitor your estradiol SHBG and free testosterone and act accordingly to lower SHBG or estradiol if either becomes problematic and therby prevent any issue. This is easier said than done as obtaining an endocrinologist who is knowledgeable and up to speed on the latest treatment protocols for TRT, hypogonadism and related meds is not easy.
That said I will make it easier for you to get enough information to get where you need to be by pointing you here;

http://www.andropause.org.uk/newforum/forum_frameset.htmThese support groups can help you learn all you need to know, but it can take a long time to learn enough to help yourself understand such matters and the need of such healthcare- leaving it to the doctors and hoping they will just get it right on your behalf just isn't a viable option in this arena unfortunately.
On a positive note I can tell you that testosterone is one of only two hormones that actually helps to reverse osteoporosis. Testosterone is an osteoblastic stimulator- osteoblasts are the human bodies bone remodeling team. They are constantly at work building bone- when we lack testosterone we lack osteoblasts but we do not lack osteoclasts which deconstruct and strip away bone. For this reason men with low testosterone are highly susceptible to having less bone re-built than that stripped away on a constant basis and resulting osteoporosis. Testosterone can help redress this balance and improve bone density.
I have osteoporosis as a result of long term low testosterone myself and am currently on TRT.
I hope you found some of this info helpful.
