While I'm waiting for a response about Tropius (see Mythbusters topic, end of page 1), I have another quirky little....something to ask.

Okay, usually I don't care too much about the genders of the Pokémon I catch (save some....special cases). However I've heard that when a Pokémon with Cute Charm leads the party, the chances of encountering a wild Pokémon of the opposite gender becomes very likely (even when said opposite gender is very rare, like in 12.5-25% range). Would this effect work on Pokémon found in the Mansion (like Eevee), or is this only applied to regular wild Pokémon?
