How should I increase testesterone level? Will it help in getting better erection?

It is true that testosterone levels become lower as men age, but it's also true that many men continue to achieve erections despite this decline. In fact, according to a Harvard Medical Report on erectile dysfunction, a man with virtually no testesoterone might still be able to have an erection. Moreover, in a large study of older men, researchers found no connection between erectile function and levels of sex hormones. So the answer isn't that simple. However, if you suspect low testosterone levels, a Urologist will be able to guide you.
