How much time it takes to come out of depression ed. will increasing testosterone naturaly by food can help..?

Depends . . .: You're describing two different issues, depression & erectile dysfunction, that respond to different therapies. Anti-depressants & psychotherapy can help make a difference in weeks to months. Depression can cause loss of libido (sex drive) & ed but there's no direct way to increase testosterone by eating any particular food. However, eating healthy & exercising regularly should help both.
