A newsiest clinical study (Vaez et al., 2022) has found that, after 12 weeks of QUR treatment, there was no significant difference in BMI and hormone levels between the QUR and PCOS groups, but patients from the QUR group had lower LH than before treatment (4.35 ± 1.62 vs. 3.06 ± 1.43 mIU/ml; p = 0.029). Here, PLOD1 is linked to polycystic ovary syndrome.
