NCT07571096

Brief Summary

This observational case-control study aims to develop a multidimensional risk assessment model for thrombophilia-related abnormalities in females with polycystic ovary syndrome (PCOS). The study will analyze endocrine, metabolic, and genetic factors associated with decreased protein C and/or protein S levels in participants with PCOS. The results are expected to provide evidence for risk stratification and individualized management in this population.

Study Population

Female participants aged 14 to 45 years with polycystic ovary syndrome will be enrolled. Participants will be classified according to the presence or absence of decreased protein C and/or protein S levels.

You may qualify if:

  • Female participants aged 14 to 45 years
  • Diagnosis of polycystic ovary syndrome (PCOS)
  • Irregular menstrual cycles are defined as follows: more than 1 year and less than 3 years after menarche, menstrual cycles shorter than 21 days or longer than 45 days; more than 3 years after menarche to perimenopause, menstrual cycles shorter than 21 days or longer than 35 days, or fewer than 8 cycles per year; any cycle longer than 90 days more than 1 year after menarche; or primary amenorrhea by age 15 years or more than 3 years after thelarche
  • No use within 3 months before blood sampling of anticoagulant drugs, procoagulant drugs, oral contraceptives, or other medications that may affect sex hormones, insulin, glucose metabolism, or coagulation function

You may not qualify if:

  • Confirmed pregnancy
  • Hematologic disease
  • History of malignant tumor
  • Use of medications within 12 weeks before enrollment that may interfere with study assessments
  • Disorders that may cause hyperandrogenism or ovulatory dysfunction, including congenital adrenal hyperplasia, Cushing syndrome, functional hypothalamic amenorrhea, thyroid disease, hyperprolactinemia, or primary ovarian insufficiency
  • Disorders that may affect protein C or protein S levels, including antiphospholipid syndrome, liver disease, or tumor-related conditions
  • In adolescents, polycystic ovarian morphology alone will not be used to establish the diagnosis of PCOS
