Effects of the severity of tubo-ovarian disease and previous tubal surgery on the results of in vitro fertilization and embryo transfer.
The purpose of this study was to evaluate the ovarian response and in vitro fertilization/embryo transfer (IVF-ET) results in patients with tubal infertility and two ovaries, according to (1) the degree and extent of pelvic disease (isolated tubal or tubo-ovarian) and (2) previous adnexal surgical procedures. A total of 549 patients who underwent 1031 IVF-ET cycles were evaluated. Significant findings were as follows: (1) No differences were found in the number of preovulatory oocytes, fertilization rates, or serum estradiol levels in the follicular phase between any classes of tubo-ovarian disease. (2) Patients with a "frozen pelvis" had significantly fewer follicles aspirated than those in any other category, although they had equivalent numbers of preovulatory oocytes retrieved and pregnancy rates. (3) Patients with previous bilateral tubal ligation had higher pregnancy rates than patients with severe tubo-ovarian disease. (4) The type of prior pelvic surgical procedure had no effect on IVF-ET outcome. Although patients with no cause of infertility other than tubal ligation had better results, these patients had previously proven fertility. We conclude that neither the stage of tubo-ovarian disease nor any history of pelvic adhesions or tubal surgery has a significant impact on the efficiency of IVF-ET.
