you need to come off everything and begin hcg and arimadex. I would use arimadex at 1/2mg 3 x wk and hcg at 250iu twice wk every wk and attempt to restore any natural test I could. The adex and hcg should help elevate sperm count and natural test over time. I would also use clomid at 100mg/ day for a couple wks and then drop to 50mg day for 2 more wks after you quit everything. Its going to take awhile, possibly a year before you are fertile again. Even on trt there is still a 50% chance of being fertile, but the choice to come off totally or stay on trt depends on how long you have been on trt up until now. If its been a year then Id attempt to drop everything, if its been longer then Id revert to a minimum trt dose of 80-100mg wk and continue on hcg arimadex regimen. U really need a fertility specialist though but for now this is what Id do personally
It shall be noticed, that in men, approximately 5% of testosterone undergoes 5α-reduction to form the more potent androgen, dihydrotestosterone (DHT), also known as androstanolone. From another side approximately % of testosterone is converted into estradiol (the primary female sex hormone) by aromatase an enzyme expressed in the brain, liver, and adipose tissues. Hence, don`t forget to take precautions to avoid respective side effects. Thereof we recommend to perform blood works and take aromatase inhibitors on cycle (if required, anastrozole preferably) and SERMs (clomifene, toremifene) during post cycle therapy (PCT).
