That's pretty seriously underweight. It's hard for your body to make normal amounts of estrogen, testosterone and progesterone when there is so little body fat - that could be contributing to her lack of libido, as well as her history of abuse.

Why is she underweight? Does she have an eating disorder? Does she exercise obsessively? Or does she have digestive problems (celiac disease comes to mind)? Should she have her thyroid rechecked? Does she have thyroid antibodies?
