Thank you, Luis, however I am no Classical Latin scholar, only Vulgar Latin which the Church uses I'm afraid.
As far as masculinity being necessary for ordination to the Catholic priesthood, I don't think for one moment that the fathers attending the Council of Trent would ever have considered for a fleeting moment that a woman could be ordained to any order, major or minor. Hence there would have been no reason whatsoever for masculinity to be stipulated, it was simply taken for granted.
As well as this, the Council of Trent was convened to refute the errors of Protestantism and the 'ordination' of women to any form of ministry was not one of those errors at the time. Protestant ministers were going to be men for the next 450 plus years.
