Abstract
STUDY OBJECTIVE: To study the presentation and causes of premature ovarian insufficiency (POI) in adolescents. DESIGN: Retrospective notes review. SETTING: Tertiary referral outpatient clinic for pediatric and adolescent gynecology. PARTICIPANTS: Adolescents with POI. INTERVENTIONS: Standard POI evaluation. MAIN OUTCOME MEASURES: Age and clinical symptoms at presentation, causative factors for POI, if identified. RESULTS: We identified 22 girls with POI, with a mean age of 15.6 years. Eight of them presented with delayed puberty, 3 with primary amenorrhea, and the remainder presented with either irregular bleeding (n = 9) or secondary amenorrhea (n = 2). For those who presented with delayed puberty, only 3 were found to have a sex chromosome abnormality. A clear cause for the POI was identified in 3 further cases. CONCLUSION: Although POI in adolescents traditionally is associated with primary amenorrhea and delayed puberty, a proportion of girls will present with irregular bleeding that might be mistaken for expected menstrual disturbances of puberty, thus delaying the diagnosis. We identified a clear cause for POI in 6 cases. Although there were no familial cases of POI, it remains a possibility that genetic reasons might be involved in the pathogenesis.
