Objectives: An increase in homocysteine (Hcy) concentration is closely related to polycystic ovary syndrome (PCOS). This study aimed to further explore serum homocysteine concentration and its influencing factors in clinically young (≤ 35 years) patients with PCOS and hyperandrogenism.

Material and methods: An electrochemical immunoassay was used to investigate the changes in serum homocysteine and related indexes in clinically young patients with PCOS and hyperandrogenism, and the results were statistically analyzed.

Results: Serum homocysteine concentration in clinically young patients with PCOS and hyperandrogenism (n = 208) was found to be significantly higher than in the control group (n = 663) (15.21 } 9.99 vs 12.56 } 7.20 μmol/L, p < 0.0001), and the total testosterone concentration (1.65 } 0.68 ng/mL) was higher in the PCOS group than in the control group (1.52 } 0.58 ng/mL), p = 0.007. The receiver operating characteristic curve showed that the area under the curve of homocysteine in predicting PCOS was 0.606, and the 95% confidence interval (CI) was 0.563–0.650 (p < 0.001). The homocysteine concentrations of the two groups were graded, and it was found that the percentage of patients with homocysteine levels > 15 μmol/L was 26.92% in the PCOS group and 19.15% in the control group; the difference between the two groups was statistically significant (p = 0.0143). The serum homocysteine levels of the two groups were higher in obese patients than in non-obese patients (normal weight vs overweight), and the difference in the control group was statistically significant.

Conclusions: Serum homocysteine concentration in clinically young patients with PCOS and hyperandrogenism is elevated, so hyperhomocysteinemia can be used as one of the potential indicators of PCOS. In the process of the diagnosis and treatment of patients with PCOS, serum homocysteine concentration and body weight should both be considered.
