While a men's schola and Gregorian Chant is great (when done properly and well-rehearsed) and two, three or four part men's polyphony especially when the harmony is CLOSE is simply incomparable, at the same time, you need to have the men showing up to sing, or you won't have any singing.
In every trad chapel I've known, there is a common theme going on with NovusOrdo parishes: women and girls are the majority of participants when it comes to singing.
In many places, as far as I know, if the priest were to say, "no more girls and no more women in the choir," it would be equivalent to saying "no more choir."
Therefore, in my view, the real problem is,
How Do You Get the Men to Show Up?
Another difficulty is, when you put out the word that more volunteers are needed to sing in the choir, the new people who respond are all too often people who cannot hear and repeat the proper pitches. They might make a sound that approximates 'singing' but they are off pitch (sing the wrong notes) and can't seem to hear the difference between the right pitch and the wrong one.
And then there is the very strange phenomenon, that for the closing hymn or "recessional" after Mass is finished, if a commonly known piece is chosen like "Hail Holy Queen," or "Holy God We Praise Thy Name," or (during Christmas season) "Angels We Have Heard on High," it sounds like the entire congregation knows how to sing just fine (with a few stray voices in the mix).
So you have people who know how to sing who never come and ask to help the choir, and you have people who offer their help and really do try to sing, but they're not capable of singing.
