Well alright, my first guess about was right and the translation is correct thenActually there hasn't been any change in Lona's arousal generation with this Prospermia. So far the only unique effect I saw that yellow text describes ingame is how it removes the g-spot removal MOD from Elise's clinic the next half day.
Of course I could of gone digging in the game files and figured that out, but I'm focused on other stuff right now.
Though now you need to see if the g-spot removal mod automatically comes back at some point, since that is mentioned in the yellow text.
