How do I raise my testosterone levels

My GP referred me to an endocrinologist. I have had problems with depression. My thyroid has been borderline underactive for ten years. I don’t take any conventional medicine for this. Do you know of any natural means that would raise my testosterone levels?
>>Testosterone levels are typically associated with male health, but it is just as important that this hormone is balanced in women as well. As women age, testosterone helps to reverse the common post-menopausal issues of decreased bone density and loss of muscle tone.
