Objective To explore the correlation between serum anti-Müllerian hormone (AMH) and 25(OH)D₃ levels in adolescent patients with polycystic ovary syndrome (PCOS). Methods Seventy-nine adolescent girls with PCOS and 85 non-PCOS healthy controls who walked in the gynecological clinic of our hospital from January 2019 to December 2020 were selected. Height, weight were measured and body mass index (BMI) was calculated.Hirsutism, acne and menstruation were evaluated by doctors on all subjects. Venous blood was drawn to detect levels of luteinizing hormone, follicle stimulating hormone, total testosterone, dehydroepiandrosterone sulfate, AMH and 25(OH)D₃, 25(OH)D₃ was further divided into insufficient [25(OH)D₃<30 ng/mL] and deficient [25(OH)D₃<20 ng/mL]level, then all data were compared and analyzed between two groups. Results Compared with the healthy control group, the PCOS group was more prone to have oligomenorrhea or amenorrhea, the incidence of acne was higher in PCOS group than in control group (all P values<0.05). BMI, the levels of AMH, total testosterone and dehydroepiandrosterone sulfate were significantly higher in the PCOS group compared to the control group, while 25(OH)D₃ was the opposite (all P values <0.05). AMH in the PCOS group was positively correlated with BMI and level of total testosterone, and negatively correlated with 25(OH)D₃ (all P values<0.05). The AMH level in the 25(OH)D₃ deficiency group was higher than that in the 25(OH)D₃ insufficient group, the AMH levels of the 25(OH)D₃ deficient group and control group were higher than that in the 25(OH)D₃ insufficient group,the differences were statistically significant (P<0.05). The 25(OH)D₃ deficiency rate in the healthy control group was 67.1% (57/85), while the 25(OH)D₃ deficiency rate in the PCOS group was 96.2% (76/79). The difference between the two groups was statistically significant (χ²=22.68, P<0.001). Conclusions Serum 25(OH)D₃ level was an independent factor significantly associated with AMH level in adolescents with PCOS. AMH and 25(OH)D₃ levels may be used as surrogate markers of PCOS risk in adolescents.
