The study claimed to confirm the effectiveness of IUI in treating unexplained infertility. However, unexplained infertility is a historical non-diagnosis. As knowledge of the causes of infertility improved the term should have been either adjusted or, as we suggested in 2006, been abandoned. With more in-depth investigations, practically all couples with infertility can reach one or more real diagnoses. Instead, the authors defined patients as having unexplained infertility (ie, inability to conceive within 1 year) under the minimal criteria of being ovulatory, having bilaterally open fallopian tubes, and normal semen analyses. They did not have to be spontaneously ovulatory but could be ovulatory following medical ovulation induction, in itself an oxymoron as medical ovulation induction is treatment. Moreover, patient selection criteria in this study did not consider ovarian reserve parameters. Theoretically, a woman could have abnormally high folliclestimulating hormone amounts, or low anti-Müllerian hormone amounts, or both, and could still be ovulatory after treatments. However, her infertility would still be considered as unexplained if pharmacological ovulation induction had made her ovulatory, yet did not lead to pregnancy.
