Abstract

• One hundred and twenty cases of endometrial tissue curettaged from the patients of primary and secondary sterility were studied by the methods of histopathologic and histochemical examination.
  The following results were obtained:
  1) The cases aged from 25 to 29 were most frequent.
  2) The pathologic lesions of the endometrium were present in 12 cases. The cases of chronic endometritis were most common and were 6(5.0%). There were 2 cases of cystic hyperplasia and 2 cases of atrophy. Each one case of tuberculosis and endometrial polyp was also present.
  3) Most cases among 108 cases after excluding 12 cases of pathologic lesions showed mild degree of glandular tortuosity and secretory activity with mild to moderate degree of predecidual change of stromal cells.
  4) The glandular secretion of PAS positive material was mild in many cases of endometrium. However, there were many cases of absence of PAS positive material. The stromal cells showed negative or mild positive PAS staining in almost all cases.
  5) The alcian blue staining revealed positivity in the glandular cytoplasm of all cases and positivity in the luminal secretion of many cases.
  6) The differences of histopathology and histochemical reaction between primary and secondary sterility were not significant.
