She can always ask for a bilateral salpingectomy. A lot of CF women have successfully had that done as IVF is still possible. If, however, she has endometriosis which is why she actually wants the hysterectomy done, then that’s a fair bit harder. I’m unsure if there’s a CF community on Lemmy, but the one on the other site had a lot of resources on how to talk with medical practitioners to get referred to someone who would do the treatment.
