With respect to this disease, androgen replacement treatment has been performed for aging male. However, available preparations of androgen are limited in Japan and each of them has both merit and demerit. Establishment of guideline for androgen replacement treatment including criteria of serum testosterone concentration is the problem, which now confronts us.
