Nice, so that pretty much eliminated my previous hypothesis:
Maybe that Cornuta's egg production in females needs to be triggered by the seasonal changes. Furthermore, those specific native dryness, humidity, and temperature may start the biochemical pathway in egg production. In other words, CB female Cornuta are not unwilling to initiate the act of breeding, it's rather that they are incapable of breeding (they have no eggs in them).
Because if my hypothesis were true then seasonal 'conditioning' is required to trigger female Cornuta's egg production, then it inevitably implies that WC female Cornuta can only breed ONCE in captivities because it's removed from the necessary egg-producing environment.

This also suggests that the seasonal changes play a role in changing the hormonal level, or sex-drive, in these frogs... just like what lumpbump had suggested previously. The below quote is from me but I simply elaborated what lumpbump had said.

it's totally possible that the seasonal changes in extended period of dryness, humidity, and temperature may alter the hormonal level in these frogs, and hence the desire for breeding. So without this "conditioning," female Cornuta would not even want to breed, although completely capable of breeding.
Interesting. This makes me highly suspect that the Japanese breeders used hormone treatment to get the F1 Cornuta to spawn babies in captivities.
