Mangas in the jump aren't exactly 5-5 on the gender ratio even if the Jump is has a really big amount of female readers.
We have some information about the ratio of male-female readers in some mangas:
Kimetsu no Yaiba: 4-6
The Promised Neverland: 4-6
Black Clover: 6-4
We Never Learn: 8-2

I found some data from 2012, although only One Piece and Haikyuu are still in the magazine. This was the male-female percent:
One Piece 48.2 - 51.8
Haikyuu 33.2% - 62.8%
Strap yourself in. I'm about to blow away all your preconception about comic and manga gender demographics. It's actually more interesting than it sou

My Hero Academia should have a big amount of female readers. Act-Age may be in a similar situation.
Yuragi-sou no Yuuna-san should have a lot more of male readers (like We Never Learn).
