News | Study finds no direct association between serum ferritin levels and fertility or metabolic health in women with PCOS
A study led by the University of Oulu in Finland and published in Fertility and Sterility found that although women with polycystic ovary syndrome (PCOS) generally have higher serum ferritin levels than other women, ferritin was not significantly associated with fertility or metabolic health.
Using health data collected from Finnish women aged 34–36 between 2020 and 2022 as part of the WENDY Women’s Health Study, the researchers examined associations between ferritin levels and clinical features of PCOS. The results suggested that neither high ferritin nor iron deficiency significantly affected the ability of women with PCOS to conceive.
High ferritin does not equal infertility or metabolic problems, and women with PCOS need not be overly concerned
Women with PCOS had significantly higher ferritin levels than the control group. This was mainly influenced by typical PCOS features such as irregular menstrual cycles, changes in menstrual blood loss, and elevated insulin levels.
‘Previous studies have observed associations between high ferritin and metabolic abnormalities such as insulin resistance and cardiovascular risk,’ said lead author Dr. Virtanen. ‘But among women with PCOS, these associations were actually weaker than among women without PCOS.’
The team also analyzed the relationship between ferritin and infertility. Neither high nor low ferritin was statistically associated with the likelihood of conception. The researchers emphasized that although adequate iron stores remain important for maternal and fetal health during pregnancy, ferritin alone is not a reliable indicator of whether a woman with PCOS is likely to conceive.
Ferritin as an inflammatory marker should be interpreted in context, not used as a stand-alone diagnostic tool
Ferritin is the main iron-storage protein in the body, and its concentration in the blood is commonly used to assess overall iron stores. The researchers cautioned, however, that inflammation must also be considered when interpreting ferritin results. Ferritin is an acute-phase protein and may rise in chronic inflammatory states such as obesity and insulin resistance, potentially distorting the assessment of actual iron stores.
A study collaborator noted, ‘This is one reason elevated ferritin in women with PCOS should not automatically be interpreted as iron overload or poor metabolic health.’
Researchers call for a return to fundamentals in PCOS care and caution against overinterpreting laboratory results
Polycystic ovary syndrome is the most common endocrine disorder in women and affects approximately one in six women of reproductive age worldwide. It is characterized by polycystic ovarian morphology, elevated androgen levels, and ovulatory dysfunction and is often associated with increased risks of obesity, insulin resistance, type 2 diabetes, and cardiovascular disease.
The team therefore emphasized that assessment of women with PCOS should not focus narrowly on a single measure such as ferritin. It should instead consider overall metabolism, the hormonal environment, lifestyle, and other factors together.
