Effect of loss of progesterone with hysterectomy
 

This isn't about bc, and specifically is about women with hysterectomies, but I think it is interesting all the same in considering the multiple influences on sexuality that apply to women, and whether the application of progesterone for cervical reasons might be a reasonable consideration for bc patients as well -- maybe just for those who have had hysterectomies, but maybe also those who have not.
