The question is not IF you recover, but what will recovery be like for you and how long will it take. Studies show from multiple and international trials using various testosterone preparations recovery in men to be (6-24) months respectively :
The use of exogenous androgens can influence the HPG axis by similar mechanisms as endogenous testosterone by exerting negative feedback in a dose- and duration-dependent fashion, resulting in reductions in ITT, blunting of FSH production, and ultimately decrease or complete cessation of spermatogenesis.29 Data specifically describing the natural history of unassisted spermatogenesis recovery after long-term TRT are lacking, but such information can be extrapolated from the male contraceptive literature.16 Multiple and international trials using various testosterone preparations have been performed and demonstrate a median time to spermatogenesis suppression to <1 × 106 ml-1 sperm within 3.5 months. Alternatively, the same data demonstrate a median time to recovery of 20 × 106 ml-1 sperm ranging from 3 to 6 months, with probability estimates suggesting recovery in 67%, 90%, 96%, and 100% of men at 6, 12, 16, and 24 months, respectively, after discontinuation of testosterone exposure.13 These data also suggest that a longer exposure to exogenous testosterone, Asian ethnicity, and older age may result in a prolonged recovery time after treatment cessation.13,30,31,32 Importantly, one must consider that these data are carefully collected in men within the tightly controlled, clinical trial environment, and may not be generalizable. Certainly, men with a prior, multiple year history of TRT or AAS use may not expect the same rate of recovery.
