Is there a permanent cure for secondary hypogonadism? i'm 30 yo and i would prefer not to inject myself every week for the rest of my life. pleasehelp

Treat the cause: It's rare for a man simply to lose his libido and need to inject testosterone weekly. I'm going to assume that you have at least one testis and are otherwise intact. I'm betting that if your physician looks hard, he/she can find an underlying cause. Prolactinoma and hemochromatosis are often-missed causes, especially at your age.
