Brief summary: This is a single-center, non-randomized, open-label clinical study to investigate the efficacy and safety of Dingkundan (DKP) combined with compound oral contraceptives (COC) in the treatment of PCOS. This study is mainly to compare the effect of COC plus DKP verse COC on reducing androgen, improving the function of ovarian and the individual metabolism. The secondary objective of our study is to explore the efficacy of DKP on pregnancy in patients with PCOS and its safety.

Detailed description: In this study, the decreased level of serum androgen was used as the main outcome index. It was assumed that PCOS patients treated with Dingkundan combined with compound oral contraceptives for 3 menstrual cycles had decreased serum androgen by 0.53nmol/L. It was assumed that the serum androgen decreased by 0.21nmol/L after 3 menstrual cycles of combined oral contraceptives alone. If α = 0.05, the test degree was 80%, and the dropout rate of 20%, considering that the sample size ratio between the experimental group and control group was 1, the sample size of experimental group and control group were 60 cases each, and 120 cases in total. All the samples were recruited from the Department of Gynecology and Women's Health Care of Guangdong Women and Children's Health Hospital.

This study was approved by the Ethics Committee of the hospital, and all participants are required to sign informed consent.

Before the study, researchers should be trained in a unified and standardized manner, including medication methods, observation indicators, judgment and treatment of adverse reactions/events, and reporting of serious adverse events.

The researcher must adequately and accurately record the research process so that the research data can be verified. These records can be divided into two categories: study documents and raw patient data. Study documents include protocols and amendments, sample informed consent forms, researcher resumes and authorization forms, and other required documents and correspondence. Original documents of patients' include patient inpatient/outpatient records, doctor's and nurse's orders, appointment dates, original laboratory reports, ultrasound, signed informed consent forms, patient screening forms, etc.

During the study period, if the subject withdraws the informed consent, or refuses the further follow-up, or loses follow-up, or dies, the sample will be disqualified.

If the subject withdraws consent, refuses to continue the study, or the investigator determines that the subject's clinical symptoms/physical condition has worsened and that the subject is no longer suitable for the study, or the subject develops toxicity intolerance, such as any clinical AE, laboratory abnormalitiesor, or the investigator determines that the subject has reached the study endpoint, or any circumstances warrant discontinuation of this study judged by the investigator, or the study sponsor discontinues the study, this study will be stop.

Anyway, this clinical study is conducted in accordance with the Declaration of Helsinki and relevant regulations on clinical trials in China. It can only be carried out after obtaining the approval of the Ethics Committee. The modification of clinical research protocols, informed documents and other materials involved in clinical research should be approved by the Ethics Committee before implementation. The investigator should protect the rights and privacy of the subject.
