OBJECTIVE: To determine whether large loop excision of the transformation zone of the uterine cervix for cervical intraepithelial neoplasia predisposes to the development of female isoimmunity to human spermatozoa. DESIGN: A prospective, controlled study. SETTING: Colposcopy and Andrology units at the John Radclife and Churchill Hospitals, Oxford, United Kingdom. INTERVENTIONS: Serum samples were collected from 33 women before large loop excision of the transformation zone of the cervix and repeated at a minimum time interval of 4 months after the procedure. Women were questioned regarding the procedure and subsequent reproductive function. A control population of 30 women not undergoing cervical surgery also underwent serial serum screening for antisperm antibodies. MAIN OUTCOME MEASURE(S): The detection of serum antisperm antibodies by flow cytometry. RESULTS: None of the serum samples before large loop excision of the cervical transformation zone had clinically significant levels of antisperm antibodies. There was, however, a significant rise in antisperm antibody levels in women following large loop excision of the transformation zone. Apparent risk factors for the development of antisperm antibodies included a short duration of sexual abstinence and the use of nonbarrier contraception after surgery. There was no rise in antisperm antibody levels in the control population. CONCLUSION: Large loop excision of the transformation zone of the cervix is a risk factor for the development of antisperm antibodies in women. Women should be advised to use barrier contraception or avoid sexual intercourse until complete healing of the cervix has occurred.
