To retrospectively survey our population of women who had undergone cervical laser surgery to determine if it adversely affected their ability to conceive or to carry a pregnancy to term.


Women who had undergone laser surgery during the period 1979-1989 were contacted and surveyed regarding each of their pregnancies. Information obtained included their age at the time of each pregnancy, pregnancy outcome, how long they were trying to conceive, and their use of contraception. The post-laser experience of the study group was matched individually for age and parity with a control population taken from the pre-laser interval of the same patients.


We contacted 1069 women; 512 responded to the survey and 433 were matched with controls. The mean study interval was 3.8 years. The study group had significantly more total pregnancies (277 versus 177 for controls, P < .001), total births (163 versus 112 for controls, P < .002), full-term pregnancies (145 versus 100 for controls, P < .005), and terminations of pregnancy (75 versus 28 for controls, P < .001). There was no significant difference in the number of spontaneous abortions (31 for the study group and 33 for controls), premature deliveries (18 for the study group and 12 for controls) or ectopic pregnancies (eight for the study group and four for controls). There was no difference in the pregnancy rate (compared with controls) between laser vaporizations and excisions.


Cervical laser surgery does not appear to impair a woman's ability to conceive or carry a pregnancy to term. There is no difference in the effect on fertility between laser vaporization and laser excisional cone biopsies.
