(from TFA):
"In a lower hyperthermia treatment, the morphology of testes and seminiferous tubules is only partly injured, and fertility indices are decreased to 10% at day 7, then recovered to 50% at day 60. In a higher hyperthermia treatment, the morphology of testes and seminiferous tubules are totally destroyed, and fertility indices are decreased to 0 at day 7."
In other words, the 'reversible' (or more accurately temporary suppression of fertility) process drops fertility down to 10%. As an actual birth control process, 10% fertility might as well be 90%.
The elimination of fertility by this method - ie to 0% - seems to be irreversible.
So the process is more accurately a method of male sterilization (for which it may indeed be valuable, if it's less invasive, less painful, etc. than vasectomy); the "contraceptive" role seems to be far less reliable than current methods by at least one, perhaps two orders of magnitude.
Only by the most extreme hyperbole could this be called "reversible male contraception".
