ABSTRACT
Unexplained recurrent miscarriage (RM) is a significant health problem for which no
effective treatment is available yet. In only 50% of couples with RM a cause can be
found. In clinical practice, a frequently asked question is whether assisted reproductive
technology (ART) is a treatment option. The scientific rationale and the chances of
success for ART in couples with unexplained RM are still controversial. Presently,
there is not enough evidence to justify IVF or intrauterine insemination (IUI) as
a treatment option. Research on oocyte donation has been reported in one article.
It is questionable whether couples with unexplained RM would undergo the potential
risks and emotional aspects of ART. There is insufficient data on whether preimplantation
genetic diagnosis improves the live birthrate in carriers of a structural chromosome
rearrangement with a history of RM. No randomized controlled trials are available
for preimplantation genetic screening (PGS) for unexplained RM. A recently published
review concluded that the live birthrate for IVF/PGS and natural conception groups
appears to be quite similar. Because evidence is lacking, we recommend refraining
from ART in couples with recurrent miscarriage.
