Premature Ovarian Insufficiency: An Adolescent Series.

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.
