That's not what is being said.
So tell me this then how is the Bishop even gonna tell if the man is cured? Look upon him during sex to have a look see?
If someone wants his wedding to be blessed by the Church, the Church will ask him whether or not the impediments to marriage apply.
Apparently the question was asked, and the answer given showed that there was an impediment to Christian marriage.
BTW his seed unless he was medically castrated {not the same thing as impotent} is still there and can be extracted.
The Church does not sanction artificial reproduction.
The RC Church tolorates a lot or breaking of it’s doctorines if the name is right. It tolorates the presence in it’s buildings and gives communion to a political family which calls for the murder of the unborn yet strains at a man and a woman being joined in marriage? What’s wrong with this picture? Something is very wrong and very missing. One set of laws for some and another set for others. But such is the state of many of todays churches. One church even invoking Christ name as it’s own leads the way in our moral decline. The United Church of Christ for example.
Now as for marriage though if the RC Church truly went by the absolute teachings given the Romans then indeed very, very, few would ever get married :>} Most of us realize the even Paul had his own prejudices and weaknesses.
