Repeated miscarriages, or recurrent pregnancy loss, is defined as having three or more consecutive miscarriages. Of couples trying to conceive, approximately 5% have two consecutive miscarriages, and 1% have three or more consecutive losses.
There are various causes for recurrent miscarriages including chromosomal abnormalities within the embryo, problems within the uterus (polyps, fibroids, scarring, septum), and medical conditions within the mother.
Treatment depends on the specific cause for recurrent pregnancy loss. Unfortunately, in approximately half of couples with repeated miscarriages, a cause cannot be found.
