Significant differences in LH, T, sex hormone-binding globulin (SHBG), PRL, and E2 between the PCOS non-ow group and the Control non-ow group, differences in LH, T, SHBG, and E2 between the PCOS non-ow group and the PCOS ow group, and differences in LH, FSH, T, SHBG, and E2 between the Control ow group and the PCOS ow group were observed (all p < 0.5, Table 2). Here, PRL is linked to polycystic ovary syndrome.
