Keep in mind that there doesn't seem to be a standard protocol for administration of TRT for women. The ranges can range grossly from doctor to doctor. Make sure your doc has experience in this area or can consult a colleague of theirs that does.
With that out of the way, the good news is, TRT for woman can really help with a lot of issues. My wife has had a full hysterectomy and went years with only using estrogen. She is also on Wellbutrin, which can have an effect on sex drive as well. We just started her on TRT 3 weeks ago, but we can report back on the results a few months down the road.
I actually did the research myself to find the doses. They ranged from 10-25mg every week (or 60-100 every 4 weeks) in other cases. Women are extremely prone to side effects, so whatever you do, take it slow and easy.
