[A collaborative study of habitual abortion in couples with normal and abnormal karyotypes].
A collaborative study in 732 couples presenting repeated spontaneous abortions (RSA) and normal karyotype and in 144 couples with RSA and chromosome abnormality has been carried out involving 18 French cytogenetic laboratories. Couples with RSA and normal karyotype were classified from prior reproductive history in order to find other etiological factors. Couples with RSA and abnormal karyotype were investigated with respect to the types of aberration and familial history. Results are compared to previous reports.
