POI impacts fertility, hormone production, and long-term health. Emerging research reveals that our understanding of its triggers has transformed dramatically.
Researchers at a Hungarian university hospital wanted to explore whether diagnosis of POI has changed over the past four decades as awareness of POI has changed. They compared two groups of patients:
Historical Cohort (1978-2003): 172 women
Modern Cohort (2017-2024): 111 women
The study tracked four main causes: genetic, autoimmune, medical treatments (iatrogenic), and unknown (idiopathic).
The researchers found a major shift in diagnoses over the last 40 years:
Unknown causes dropped by half, falling from 72.1% to 36.9%.
Cases caused by medical treatments jumped more than fourfold, from 7.6% to 34.2%.
Autoimmune-related cases more than doubled, rising from 8.7% to 18.9%.
Genetic factors stayed steady, moving slightly from 11.6% to 9.9%.

The drop in unknown cases may suggest that diagnostic testing is improving as sciences is evolving. Better genetic and autoimmune screening allows doctors to pinpoint exact causes, thus reducing the number of cases deemed as idiopathic.
The rise in treatment-induced cases highlights a critical modern need. Women facing cancer therapies or major surgeries require proactive fertility counselling. Modern care relies heavily on comprehensive family history assessments and expanded genetic screening. Uncovering a familial link not only provides answers for the patient but also allows family members to seek early screening and protective care.
Turning research into self-advocacy:
If you are facing medical therapies that may affect fertility, bring this research to your oncology or surgical team. Use the stark rise in iatrogenic cases to insist on immediate, pre-treatment fertility-preservation counselling.
Talk to family members- tracing autoimmune disease or family history of POI or early menopause might be important for understanding your diagnosis.
