Happy WAAAAAGHdependence Day!

I need some Loreissars to help with laying some foundations for a couple of armies and general game world I’m developing.
Are human women more naturally inclined towards Psyker/Blank genes?
I’ve been getting more and more into the books and lore YouTubers lately, and it does seem to me that no small majority of key ‘warp attuned’ characters seem to be female. Now obviously there are plenty of male Psykers, otherwise there’d be no librarians, or Malcador, Da’Big E and so on, but there does seem to be a lenience with the standard Humans, especially concerning the Pariahs.
The glaring one straight up is the Sisters of Silence, but in the books that I’ve read as well, I have heard of at least one male blank, but another three female blanks to go with him, so there’s a definite weighing in some way. So I was wondering if there has been any lore established on this?
I figure there might be two possible reasons:

1. A meta-level reason of “we need more chicks who ain’t just guardsmen, Inquisitors or the odd Commissar, we can’t make them Astartes, so lets make them Psykers instead.” So it’s more just a need to get more character variety.

2. There’s an actual lore-founded tendency for women to be more connected to the warp.
   Or... is there a 3 I’m missing where in those individual moments the writers/developers simply just felt like writing female characters?

Cheers.
