Recurrent pregnancy losses (RPL) are characterized by the occurrence of more than one spontaneous pregnancy loss. It is caused by different known factors, but about half of the cases remain without an explanation. Efforts are being done in the scientific community to solve this cases. In this study, the investigators aim to investigate genetic factors that might predispose to RPL, as well as the influence of the uterine microbiota (microorganisms that normally live in the uterus of women).

Control group: at least two full-term pregnancies and no history of difficulty getting pregnant, pregnancy loss or other infertility factors.
