What Is Unexplained Infertility?
Unexplained infertility is diagnosed when standard fertility testing does not identify a clear cause of infertility.
What It Means
Unexplained infertility accounts for approximately 15 to 30 percent of infertility cases. It means that ovulation, semen analysis, tubal patency, and uterine anatomy all appear normal, yet pregnancy has not occurred.
Treatment Approaches
Treatment typically follows a stepwise approach: timed intercourse with ovulation induction, intrauterine insemination (IUI), and then IVF. Many couples with unexplained infertility achieve pregnancy through IVF, which bypasses potential undetected barriers to fertilization.
