Unexplained loss

Although researchers are constantly trying to find new causes for pregnancy loss, there will always be some couples whose miscarriages remain unexplained.

Indeed, many cases of recurrent pregnancy loss will remain unexplained even after detailed investigations have been performed.

However, if a case of recurrent pregnancy loss is unexplained, it means that the couple in question most likely aren't affected by any of the major causes that crop up.

This is a good thing, because the prognosis for a future successful pregnancy in the unexplained group is usually better than it is for couples in which a recognised cause is identified.
