If the low testosterone problem is not severe, you may wish to consider alternative therapies. There is some link between diet and testosterone levels in the body. Zinc and selenium have been found to be strongly correlated with testosterone levels, according to researchers. Zinc is one of the components in the chemical makeup of testosterone. Low vitamin D levels have also been linked to infertility caused by low testosterone. In general, a healthy, well-balanced diet will help your body regulate its own hormone levels. Cutting out smoking and alcohol are a good idea so that your body can better focus on regulating its hormone levels.
