Ovarian failure phenomena after hysterectomy

Previous studies have shown that simple hysterectomy with both ovaries left intact may cause ovarian failure. Questionnaires on climacteric symptoms were mailed to 243 patients between 27 and 42 years old who had been hysterectomized during the past ten years in the Kiel University obstetrics and gynecology clinic. From the 164 replies we found typical signs of ovarian failure in 39%. Some of the patients were asked to undergo endocrinologic investigation, which showed biphasic cycles in most cases. However, the average progesterone and estrogen concentrations in the suspected luteal phases were lower than in healthy women in the same age group.
