We performed laparoscopic surgery for two women after repeated failure of in vitro fertilization with intent to increase the possibility of pregnancy. First case was a 32-year-old woman with functional infertility. She underwent diagnostic laparoscopy and mild endometriosis was detected. She became pregnant with her second IVF-ET trial after the surgery, but miscarried. She failed to become pregnant with following 5 trials of IVF-ET although good quality embryos were transferred in all trials. We performed laparoscopic surgery and treated her for mild endometriosis. She became pregnant with the next IVF-ET 2 months after the surgery. The other case was a 34-year-old woman with functional infertility. She underwent embryo transfer 4 times including 2 frozen-embryo-thawed transfers. She could not become pregnant even though good quality embryos were transferred in all trials. We performed laparoscopic surgery and treated her for mild endometriosis. She finally became pregnant with the next frozen-thawed-embryo transfer 2 months after the surgery. IVF-ET is regarded as the final treatment for infertility. But even after repeated failure of IVF-ET, laparoscopic surgery will able to be an effective treatment for some patients with functional infertility.
