Varicoceltomy

I am 28 years old currently on trt and hcg, have a probable grade 3 varicocele on left side. Would it be smart to get the surgery now while on TRT or should I wait until I taper off when I went to become fertile again? It make sense to get he surgery now since I am on TRT and don’t have to worry about significant muscle loss since I won’t be training after the surgery? Or is it better to wait to see how fertile I can get once off. P.s yes I know TRT affects it significantly but I’d rather get the varicocele fixed now than later? Thoughts? Advice? Experiences?
