We ultrasonographically classified thirty-three patients with polycystic ovary syndrome in three groups; general cystic pattern (GCP), peripheral cystic pattern (PCP), and mixed type
(MT) and compared the clinical symptoms (obesity, hirsutism, menstrual irregularity). The results are as follows:
　1) Patients with GCP and MT are often obese.
　2) Hirsutism was more frequent in patients with PCP.
　3) The frequency of oligomenorrhea was much the same in the three groups, and a secondaly amenorrhea of grade 2 existed only in case of GCP.
Thus, In cases of polycystic ovary syndrome, the clinical symptoms differ and there are variations in the pathogenesis.
