wait if repeated stimulus is the reason it doesn't work, why cant we have an LH and FSH pump just like diabetes pumps work? this would grant you high test ( as long as it isn't enough to cause scaring of the testicular cells) and fertility.hCG + rFSH preserves fertility on 250-500mg testosterone cycles for long periods (often 1–2+ years) by restoring high intratesticular testosterone and supporting Sertoli cells.
It is not indefinite mainly because natural LH/FSH is pulsatile; continuous hCG causes gradual Leydig cell desensitization and less efficient signaling than natural pulses. Supraphysiological T and individual factors can also contribute to slow decline over time. Regular semen analysis is key.

mainly for medical infertility—not high-dose exogenous testosterone use.
A lot of studies do point out the amount of testosterone we can tolerate before testicular atrophy accurs is quite high. So I think it could be viable even above trt dosages.
