Unexplained infertility is used to describe a diagnosis in which there is no known cause of infertility. About 5%-10% of cases of infertility in women cannot be explained. Patients are usually diagnosed with unexplained infertility when examinations show no evidence of anovulation, the fallopian tubes are unobstructed and the number of motile sperm is considered to be within normal values. Although not diagnosed with the factors listed above, patients should keep in mind that they cannot be ruled out as they may be difficult to diagnose.
