ABSTRACT
Classification of recurrent miscarriage An underlying cause is most likely to be found if the repeated miscarriages occur at a similar gestation. First trimester losses account for 75% of recurrent miscarriages and second
trimester losses the remaining 25%. Even if a cause is found there is always the possibility that future miscarriages might be due to another cause, in other words they are of a sporadic nature and thus any treatment that is commenced has to allow for the fact that future miscarriages may not be due to the condition that has been treated.
