What causes bilateral testicular atrophy if i had a left varicocele and it was fixed? Shouldn't that one be smaller than the right?

In brief: See answer

There are actually many potential causes of testicular atrophy, fortunately most of which are quite uncommon.
Bilateral atrophy would suggest more of a congenital (klinefelter's syndrome most common) or systemic cause (use of steroid medications/body builders). You are correct in that a varicocele can cause atrophy on the same side and much less likely on other side unless bilateral varicoceles.

In brief: Not from varicocele

Correct that left testis might be smaller than right from original effect of varicocele upon testis.
Possible explanation for bilateral testicular atrophy following varicocele surgery could be bilateral laparoscopic spermatic cord clipping or ligation, provided surgery was performed laparoscopically. Or you had right orchidopexy surgery some time past ; later had left-sided spermatic vein ligation.
