Background: Surgical operation for benign ovarian tumors creates a potential risk for the ovarian reserve. Ovarian procedures including excision of cysts (cystectomy) are very commonly performed worldwide for various disorders.
Objective: To study the long term effect of ovarian surgery on blood level of anti mullerian hormone.
Patients and Methods: The present study was a prospective cohort study of patients who have benign ovarian tumor which carried on Patients from December 2019 to October 2020 at Obstetrics and Gynecology Department, Faculty of Medicine, Al-Azhar University.
Results: There was a significant decrease in Anti mullerian hormone ( AMH ) post operatively by 25.79%. There was a significant relation between level of AMH and age of the patients. The old age had a low level of AMH. Also, the bilateral lesion showed a low level of AMH less than the unilateral lesions. The cyst size more than 5 cm showed a negative relation with level of AMH. The log duration of surgery had a negative effect on the level of AMH. The endometeriotic type showed a significant decrease in AMH level more than the other histopathological findings.
Conclusion: Serum AMH levels could be preferred in determining the indication and selection of operative methods for benign gynecologic conditions, especially endometriomas.
