title: Therapeutic intrauterine insemination (TII)--controversial treatment for infertility.
abstract: The literature on therapeutic intrauterine insemination (TII) is confused because of lack of homogeneity in case selection, differences in executing the procedural steps, and the manner of evaluating and reporting results. This review compares results from Norfolk with those in the English literature. Special emphasis has been placed on separately analyzing each step of the procedure and presenting results of different authors in a comparable fashion. Including all etiologic factors and types of cycles, the term pregnancy rate per cycle was 3% for Norfolk, 2.6% to 6.2% elsewhere. Patients receiving TII in stimulated cycles did significantly better than those receiving TII in natural cycles, in terms of total pregnancy rate per cycle (p = 0.002). In male factor infertility, term pregnancy rate per cycle was 1.1% in Norfolk, 4.7% to 6.2% elsewhere (perhaps because of stricter criteria in Norfolk). In cervical factor infertility, term pregnancy rate per cycle was 4.5% in Norfolk, 2.7% to 11% for others. For unexplained infertility, Norfolk had 5.8% term pregnancy rate per cycle for natural cycles, 8.3% for stimulated cycles. Best published prospective results were 23% for stimulated cycles. TII seems to have a very low efficiency rate judging from term pregnancy rates per cycle. There are clear data indicating the need for redefining the indications.
