Prognosis for couples who have experienced repeated pregnancy loss

To determine whether amniocentesis should be recommended to couples who have had multiple spontaneous abortions, we obtained information on the subsequent pregnancy outcome for 70 couples who had had two or more pregnancy losses. Fifty-two (74%) had one or more successful pregnancies, resulting in 64 newborns, all but 1 of whom were normal; the abnormal infant had a normal chromosome analysis.
