By the time of TNG, though, Vulcans may have dropped their veil of secrecy and quite a bit about their biology had long since been made available in the Starfleet Medical database.
Maybe not. By the time of Voyger, the EMH seem to know basically what pon farr was, but still needed to call Tuvok down to sick bay to ask some detailed questions.
Personally, I'd like to think that after the events of Amok Time, both Kirk and McCoy would have been discrete enough to keep their mouths shut about what happened. Certainly not filing report, or entering information into the Starfleet Medical database.
