Many guys cant seem to get the girls pregnant for some time even though the testosterone comes back.
There is some testosterone that is used inside the testicles called intratesticular testosterone or ITT. What this does is kind of fertilize the sperm so it can be active or mature or something like that. I know it has to be there for the sperm to be good.

If anything right now, you might have a fertility issue and nothing wrong with your androgens.

But, knowing how bad you atrophy, then you can always run HCG during your cycle and this will actually cause the testicles to produce testosterone.
Now granted FSH is not there to tell the sertoli cells to go to work, but HCG mimics LH which tells the leydig cells to go to work.

There is something called HMG that has both LH and FSH, but it is terribly expensive and is used in men for fertility.

The balls will come back mate, but you will just have to wait.
My bro had some massive testicular atrophy, and after a year his nuts were normal, but he was kind of jacked for about a year.

So, now you have the bigger picture of what is going on.
