METHODS OF TESTOSTERONE THERAPY
Methods and systems for preventing or reducing side effects of testosterone replacement therapy (TRT) by administering a testosterone formulation multiple times per day are disclosed. The methods of the present invention enable men who cannot tolerate previous TRT regimens, e.g. because they wish to attempt to conceive or are at risk of developing cardiovascular side effects, to receive TRT treatment.
