RESUMEN
101 women were treated because of sterility in the Gondar College of Medical Sciences, Gondar/Ethiopia, in the years 1987/88. The results revealed some typical difficulties in diagnosis and treatment of sterility in developing countries, arising from limited technological facilities and special characteristics of the group of treated patients. In 61 women a final diagnosis could be made. The main cause of sterility was complete tubal occlusion in 65.6% of the cases due to a high incidence of pelvic inflammatory diseases in the investigated patients. Ovarian causes accounted for only 18%. The importance of the male factor was not evaluable due to a traditionally conservative attitude of most men against sterility investigations. Chromolaparoscopy in combination with endometrial biopsy in the second half of the cycle were well suitable for clearing most of female causes of sterility.
