Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. As men advance in age, their levels of testosterone naturally start to decrease. Testosterone, the male hormone, plays a vital role in many body functions, and low testosterone levels can leave men tired, uninterested in sex, infertile and with thinning bones. -About the pros and cons of testosterone replacement therapy, I can say that testosterone improves bone density, anemia, but may pose cardiac risk and also increase the risk for prostate cancer. The possible cardiovascular health outcomes of testosterone replacement therapy can be acute myocardial infarction, angina, stroke, transient ischemic attack, as well as sudden cardiac death. You need to know is that testosterone therapy isn t a substitute for taking care of overall health. While testosterone may play a role in their overall health, it needs to be viewed in context with other factors like poor diet and no exercise or alcohol abuse (like in your case). I suggest to consult physically a local endocrinologist and to discuss with him the benefits and risks of testosterone therapy in your case. Final decisions about testosterone treatment for you will depend on the question if you have more benefits or if you have more risks from this therapy . Hope this information is helpful. If you have other health queries, feel free and ask. Take care.
