I think it is because few women besides the noble classes were allowed to learn to read and write - or learn in the temple with men so they didn't. I think just because it was a patriarchal society that by and large oppressed women does not mean this was meant to always be the way. Many other religious customs have changed, obviously. I see no reason why that shouldn't, too - and has in many denominations.
If there are no original biblical documents written by women (or haven't been found except significant bits of the Gospel of Mary Madeleine which isn't counted as biblical - maybe it should be? ) at least women can interpret the texts through our own eyes too and apply the best and leave the rest - IMO. Just like has always happened. I don't believe Jesus intended for the church to remain sexist. He had female followers - maybe they wrote things or not - maybe they were destroyed ages ago or not. Nevertheless, I think we should 'hang onto that which is good' as seen through the lens of our own times.
