Unexplained infertility, sometimes called idiopathic infertility, accounts for 10 to 30 percent of all infertility cases according to research published in the Journal of Clinical  Medicine. That means up to one in three people seeking fertility treatment will hear some version of "we don't know why this isn't working."

Unexplained infertility is one of the most psychologically difficult diagnoses to receive. Not because it confirms something is wrong, but because it refuses to tell you what. There's no clear problem to solve, no targeted treatment to pursue, no reassuring explanation to hold onto. Just uncertainty stretching indefinitely forward.

If you're navigating this, you're not alone. And you're not imagining how hard it is.
