For some, the method won't work even with increased wear time. Admittedly, your sperm test results will change, but these people will not reach the contraceptive threshold.
No specific clinical data on this for the moment, but feedback from a few tens of thousands of people suggests that around 3% of the population is heat-resistant.
For the moment, no correlation or hypothesis on the origin is possible.
If you don't reach the threshold in 6 months, with the right tool, the right application and increased wearing time, consider that it won't work for you. You'll have to switch to another contraceptive method.
