[Cytogenetic studies in women with primary amenorrhea (author's transl)].

During the past 10 years, 106 women with primary amenorrhea were studied. According to the X chromatin determination the cases were subdivided into 2 main groups. In the X chromatin negative group the Y chromatin positive and the Y chromatin negative cases were differentiated by fluorescent methods. The diagnosis was made according to the chromosome analysis. The X chromatin positive cases were classified following in detail clinical and cytogenetic studies. In our series, 50% of the cases showed chromosomal abnormalities whereas the literature reports 20-25% chromosomal abnormalities.
