Well, I'm sure there's plenty of issues with that statement that everyone else will get right on telling you, OP, but while they may or may not convince you, here's my two cents in a somewhat different direction that you might find more persuasive: Hermaphroditism is a well established thing in nature (and in Fallen London, see: a certain species of giant bats), and for good reason, although it has its trade-offs. And I despise the tendency some people have of always referring to hermaphrodites by female terms (especially when it comes to people that became hermaphrodites who were men to begin with, that really grinds my gears). Therefore, even disregarding all else, the female sex is not the only sex in nature that can reproduce.

Not to mention asexual methods of reproducing, such as binary fission, budding, vegetative propagation, sporogenesis, fragmentation, parthenogenesis, and apomixis, to name a few. And there's the matter of biology being, like many other things, less restrained by Law down here (and by lower case law, for that matter, people can get away with all kinds of weird science down here simply because the coppers have more important things to deal with), not to mention any weird crap the Judgements could have done to its form, since if you make the rules, you can flout them as you will.

Ultimately, we can't really assume anything, here. As far as I know, at least, I'll be the first to say I'm no expert of Bazaar lore, there might be a more comprehensive answer somewhere.

Your assessment of what the Bazaar's lover did is... colorful, but it's not exactly untrue, as far as I'm aware. But... if men never held a flame for lovers that did incredibly awful things to them, well, maybe the world would be a better place. At the very least, we'd have a few less mopey love songs, and that would be a blessing in itself. Thankfully, I don't have to deal with that, having been happily married since age six (kinda).
