Recurrent miscarriage - what is it?

“Recurrent miscarriage affects about 1% of couples and is defined as the loss of two or more consecutive pregnancies before 20 weeks of pregnancy.”

This is a distressing and emotionally challenging problem for couples who want to start a family. This clinical context often raises doubts in couples about whether there is something wrong with them (especially the woman) that is preventing them from carrying the pregnancy to term and whether they will ever be able to carry the pregnancy to term. Although this clinical situation deserves careful study, the main cause is related to the complex process of human reproduction in which many embryos with genetic alterations are generated (which happens in all couples) but in some women, they are able to implant and continue their development in an initial phase, but later, due to the existence of malformations, they end up not being able to continue their development. 

The good news is that, since in the vast majority of these couples there is no maternal or paternal cause for repeated miscarriage, the probability of a couple who have already had 3 or 4 miscarriages having a full-term pregnancy in the subsequent pregnancy is greater than 75% if the pregnant woman is 30 years old and greater than 60% if the pregnant woman is 40 years old.
