I'm a 40 year old woman who feels like no one takes me seriously.
For example:
I can say something -ignored and dismissed, if my husband says it - it's believed and everyone falls over themselves to do something about it/agree with him 
I also have quite a lot of knowledge in a specific area. I often respond to posts on an internet group when questions in this area arise, but find I am frequently ignored. However when a male or two come along and respond, even if they say the same thing I did, everyone takes on board their advice instantly and thanks them
Is this just a male/female unconscious bias thing? Or is it the way I'm putting myself across?
It happens in RL too.
