Hysteroscopy may be justified after two miscarriages.

BACKGROUND
Recurrent pregnancy loss is traditionally investigated after three or more consecutive pregnancy losses. Although there is a trend to start investigation after two miscarriages, data are not available to date to justify this approach. We sought to compare the frequency of uterine anomalies between women referred to hysteroscopy for repeated miscarriages after two, and three or more, miscarriages respectively.


METHODS
A retrospective analysis of acquired and congenital uterine anomalies in all patients undergoing hysteroscopy for repeated pregnancy loss at an academic and referral medical centre.


RESULTS
Hysteroscopy was performed on 165 women referred for recurrent pregnancy loss: 67 after two and 98 after three or more consecutive miscarriages. The rate of uterine anomalies did not differ significantly and was 32 versus 28% respectively.


CONCLUSIONS
Hysteroscopy may be justified following two spontaneous pregnancy losses.
