Direct intraperitoneal insemination (DIPI) for the treatment of refractory infertility unrelated to female organic pelvic disease.
344 couples with infertility unrelated to female organic pelvic disease underwent Direct Intraperitoneal Insemination (DIPI) for a total of a 429 DIPI cycles. Pregnancy per couple was 16.5% and per DIPI cycle 13.2%. DIPI was particularly effective in cases of infertility due to cervical mucus insufficiency and unexplained infertility with results respectively of 33.7% and 30.4% per couple and 30.7% and 28.7% per DIPI cycle. On the contrary, the results regarding male subfertility were 12.5% per couple and 10.5% per DIPI cycle. A significant difference was found (X2 A = 16.48, p less than 0.001) between these results and those of the group composed of cases of cervical mucus insufficiency and unexplained infertility. In cases of antisperm iso- and autoimmunization the results were on the whole poor, and were in any case influenced by corticosteroid pretreatment. The Pellet Swim-up Test (PST) proved to be a good prognostic sign for success of DIPI, since a significant difference was found between the PST group greater than or equal to 1.5 X 10(6)/ml (pregnancy per couple was 19.7% and per DIPI cycle 17.2%) and PST group less than 1.5 X 10(6)/ml (pregnancy per couple was 6.8% and per DIPI cycle was 4.5%) (X2 = 11.4. P less than 0.001).
