Yes this is a troll post but, for anyone interested, I have direct experience with this.
>wife and I married for three years
>Catholic and having very Catholic intimate time with each other
>still no little anons
>we go to the doctor and have tests done
>she's fertile and seems fine
>I just need to tested now
>"Jerk off in a cup, anon"
>Wife and I look at each other
>I ask if I can come back in a few days, I'd need to ask my priest first
>The doctor stifles a laugh and says that's fine
>Priest tells me that the prohibition on oral sex and masturbation in marriage is primarily because of Onanism, specifically distorting the sexual act and trying to not have children
>If I'm jerking into a cup in the context of marriage, for the express purpose of procreation (we're trying to have kids) that's permissible
>Porn or self-abuse are out of the question
>Doctor seems humored when we come back and say that we can so that
>I get the cup
>Wife does her magic in the doctor's office bathroom
>I'm not infertile either
>She gets pregnant a few weeks later
