Early and late pregnancy outcomes in women treated with cold-coagulation versus LLETZ cervical treatment for cervical intraepithelial neoplasia; a retrospective cohort study.

We found that women who received LLETZ treatment when compared to cold coagulation had higher spontaneous preterm birth rates in their subsequent pregnancy and miscarried more frequently in the first trimester, and demonstrated an increased early miscarriage risk that persisted for more than a year after excisional treatment.
