No harm is doing T only for a period of time then going then deciding later to supplement with HCG. not to worry. Ive had men do T only for almost a decade then start HCG and everything returns to normal. If your equipment works before you started treatment then HCG should restart HPTA no problem. Doctor should of asked you 3 questions and if you answer yes to any of them then HCG should be given.

1) Does testicular atrophy bother you?
2) Do you wish to keep fertility intact while on treatment?
3) Do you wish to father children while on treatment?

If you answered YES to any fo these questions and are Secondary Hypo then HCG is right for you.
