[Repeated spontaneous abortions: discussion on its etiologies]. / Les avortements spontanés répétés: mise au point des étiologies.

Spontaneous abortion (SA) is the most common complication of pregnancy and is estimated to be between 15 to 20% of all clinical pregnancies. However for "recurrent spontaneous abortion" (RSA) the frequency is more difficult to determine (between 0.05 to 1%). The purpose of this paper is to review the literature concerning RSA etiologies. Particular attention has been paid to the male factors contribution in RSA. Because of the poverty of controlled studies, answers to questions about the RSA are very difficult.
