I dont think the hermetic principal of genderism applies to the egyptian idea of uniting different facets of the selves, or the connection is tenuous enough as to need a different definition of gender.
Genderism is a principle applied to forces, or symbols, while gender amongst humans is dependent on roles. The quintessential ideas surrounding mother and father can be found throughout western mythos, (Eastern mythos, to my knowledge, differentiate them as polarities rather than dualities).
... Mother and father would only give a duality to the adult cycle though, the rational, responsible. there needs to be a formula of approach which is typical of female and male elements respectively.
Alot of human understanding is preserved through stories, stories designed for men talk of events, the setting only matters as much as it related to the events therein, while stories designed for women are about the setting giving value to the event, the whole romantic ideal of women usually stem from a setting which builds enough hype for an insignificant gesture to become mind boggling. the search for a mate is also similar, in the way that women will usually adapt to any sexual or cultural tendencies if the setting made those choices appropriate, while a man will already have a specific culture and sexual tendency in mind before finding his desired mate.
problem here is that I'm still defining male and women at a stage in which they can settle down, which the rational adult has a tendency for. the formula of setting vs event can be applied accross the board, but it does not seem like enough information...
