Is it permissible to use artificial testosterone and inject it weekly for life to treat general weakness, depression, fatigue, and low muscle mass, in addition to using human chorionic gonadotropin to increase fertility, under medical supervision?

Testosterone is the main male sex hormone, and it is used to treat low levels of it. The hormone HCG affects ovulation and fertility in women, and it increases or restores testosterone production in men. There is no harm in taking these two hormones under a doctor's supervision if their benefits outweigh their harms.
