My inner research geek totally loves that you've thought through how to make mpreg biologically possible. And now I know who to come to if I'm ever struck by an mpreg idea and I need to make it plausible, for myself if no one else. *g* (Actually, my brain has started mulling over which other of the boys, besides Jay, it might be okay with making pregnant. Mark is, not at all surprisingly, leading the pack. Though Howard also has a certain attraction.)
