The process by which fields gradually becoming dominated by men gain in perceived value, to the point where it's often forgotten that they were originally dominated by women (e.g. computers, Star Trek fandom); and by which fields gradually becoming dominated by women lose perceived value, to the point where it's often forgotten that they were originally dominated by men (e.g. nursing, secretarial work).

A play on the word "gentrification."
Nursing has suffered some serious mentrification for people to forget that it used to be mostly men!

Get the mentrification mug.
When something once known as something made by or popular with women is suddenly taken over by men and essentially becomes something that women can't be interested in/partake in anymore. Then said thing will be vigorously protected by gatekeepers who will try and keep women out of it and will shun women still in the community. This can work in reverse with women also, which can be called Womanification.
Woman 1: Remember when Star Trek was something you and I would talk about in our living rooms over tea before all of this convention stuff came around?

Woman 2: I remember that quite clearly, now I can't even mention I like the show around other fans. Otherwise they'll bombard me with questions like "Who was the very first captions' mother's name????" rudely and expect me not to answer, and when I do they just insult me and call me a 'fake fan' anyways!

Woman 1: Damn, the Mentrification of Star Trek really hit hard huh?
