Unexplained Infertility

Health care providers diagnose a woman with unexplained infertility when the infertility examination shows that ovulation is occurring with no obvious abnormality, the fallopian tubes are unobstructed, and there are adequate numbers of motile sperm.1 About 30% of cases of infertility in women cannot be explained.1 More advanced testing may determine the cause of infertility, but knowing the exact cause may not be necessary.

When a specific cause is not determined for women and when male infertility has also been ruled out, the health care provider may begin treatment to improve the chances of conception and then progress to more complex fertility treatments.
