Polycystic ovary syndrome (PCOS) is a hormonal disorder associated with the endocrine system that is found in around 10% of women during their fertile years. This disorder includes the development of sac on the ovaries that are filled with fluid accompanied by hormonal imbalance as well as metabolism issues. In our study, FSH/LH ratio strongly correlated with the LH concentration. Various studies have shown that FSH/LH ratio is elevated secondary to lower LH and not due to higher FSH concentrations ( 3, 15, 16 ). However, Mukherjee et al. reported that 11 out of 14 patients had elevated FSH/LH ratio in their study ( 5 ).In young women without PCOS, the ratio of LH to FSH is approximately 1:1, while women with PCOS might see this ratio as high as 2:1 or 3:1.
