A recent study from the University of Oulu, Finland, has found that women with polycystic ovary syndrome (PCOS) tend to have higher average ferritin levels compared to women without the condition. However, these elevated ferritin levels do not appear to significantly impact fertility or metabolic health.
The study, part of the Women’s Health Study (WENDY), conducted between 2020 and 2022, explored how ferritin levels affect the health of women with PCOS. Ferritin, a protein that stores iron in the body, is often used to assess iron levels. The findings show that factors such as irregular menstruation, menstrual bleeding volume, and elevated insulin levels—common symptoms of PCOS—are linked to higher ferritin levels. Despite this, the association between high ferritin and poorer metabolic health was weaker in women with PCOS than in women without the condition.
One key takeaway from the research is that iron deficiency does not seem to be associated with infertility in women with PCOS. While maintaining adequate iron stores is essential for the health of pregnant women and their babies, the study concluded that low iron levels are not a cause of infertility in women with PCOS.
PCOS, which affects roughly one in six women, is characterized by polycystic ovaries, irregular menstrual cycles, elevated androgen levels, and an increased risk of diabetes and heart disease. Despite the link to metabolic issues, the role of ferritin in PCOS remains unclear, and the findings challenge previous assumptions about its effect on fertility.
In interpreting ferritin levels, the study emphasized the importance of considering inflammation markers, as ferritin levels can rise in response to inflammation, potentially skewing the results.
