I would like to offer that anything not specifically within the rulebooks being added _is_ a house rule. (That, of course, is not the only classification of a house rule).
I would also agree that the authors of the FR books are paid to write brilliant works of art to capture the characters in stories that give them flesh, not to study and understand everything about the way the actual game works.
What I would suggest is that those who wish to RP magic 'possibly affecting the birthing process' continue to do so. I think, apparently as Horace does, that this is a great idea. I don't agree that (without a house ruling by the Admins) this should be specifically how it should be RPed.
I believe that those who wish to RP this also take into consideration, when not pregnant, the idea of their 'possible harmful affects' being implemented into actual game code. I could see people casting 'Shadow Walk' assaulted by a horde of Shades when they accidentally slip through the wrong region of the Plane of Shadow - or worse, being captured there by someone just waiting for such a foolish adventurer. I would like those same people to think before casting 'Trollish Vigor' that there is a chance to permanently lower their charisma in doing so. Those same people who cast spells such as 'Gate' to imagine their character being drained of all stamina for a duration of time.
Still sound plausible? Sure, maybe, but I don't think we'd have so many willing to play casters.
