Honestly I was thinking the jealousy thing also. You are not JUST doing secretarial stuff or answering phones which is more or less known as the lower level jobs (from my own personal experience & probably my own prejudices).

I had my BS degree & had a career in computer design engineering & worked mostly with ONLY MEN doing military contracts back in the late 1970's - 1993. I ended up having a break down at the point when all the contracts were ending & aerospace was dying & I ended up in what I felt was a glorified secretarial position in a department with mostly women including a woman manager (which I totally hated). I had a difficult time respecting women engineers after working with the men because most didn't know what they were doing but acted like they knew it all. There were a couple of women engineers that I enjoyed working with but most were in a totally different place than I was coming from.....& the pettiness was appalling.

Personally I would just be nice to them & basically tolerate them but don't get involved in anything social with the women & just focus on your own job & doing it & learning as much as you can....your own personal growth & future in the area you are enjoying & working in is where your focus needs to be & just let the other crap be in passing......perform as a professional & if necessary....keep those airs about you....don't stoop to their level as it will only backfire on you....basically the attitude of tolerating them when you have to would probably be in your best interest without doing it in a snotty way.
