Relative mRNA expression of GPX4, HP, HAMP, A2M, FTH1 and NCOA4 gene was downregulated in PCOS patients with short cycle length (< 28days) compared to females with long cycle length (> 35 days), although the difference was statistically non-significant (Fig. 3A). This evidence concerns the gene FTH1 and polycystic ovary syndrome.
