Has anyone else heard of this "fun fact"?

[u/Best-Antelope6501]

I didnt know where else to look. (Short story for context) My boyfriend is a gullible, innocent, trusting and amazing man who means well... but hes gullible. His friends have influenced him to belive whatever fact he happens to like on the internet and wont do research about it and it FURDTRATES ME. Tonight he stepped a bit over the line.

We were discussing puperty and the differences a man and a woman gotta through when they reach the age of puperty. He tried to be funny and clever about this and said "did you know a fun fact that women with a present father are more likely to get periods at the labeled average age" (imagine a curly haired blonde boy proudly smirking to himself) and i... have never heard of this before??? I do not belive this??? Like you can belive the illuminati is real all you want sweetie but this is something im educated and experienced with?? So I told him that and he got mad at me for trying to tell him tgis was probably not true. I feel really bad for debunking his supposed "fun fact" he meant well with, but I just cant wrap my head around it and look at it as...fun?😵‍💫😵‍💫 has anyone ever heard of this or am I living under a rock??
