Inclusion criteria

Inclusion criteria: All patients aged 18 to 45 years with PCOS presenting with symptoms of oligomenorrhea to the gynecology clinics of Valiasr Hospital and Rouyesh Infertility Center in Birjand, who have been diagnosed with PCOS by a gynecologist using the Rotterdam criteria, will be included. Malignancies, pregnancy, and other hormonal causes of oligomenorrhea must be ruled out at baseline, ensuring that oligomenorrhea is solely due to PCOS. Furthermore, patients who are reluctant to use conventional chemical drugs or invasive/semi-invasive procedures, and for whom the gynecologist deems traditional medicine treatment and a 12-week observation period without conventional interventions safe and non-detrimental, will be voluntarily referred to the researcher. Participants will enter the study after providing informed consent.

Exclusion criteria

Exclusion criteria: 1. Co-morbid diabetes, dyslipidemia, or hypertension.2. Presence of treated or clinical hyper/hypothyroidism.3. Co-existing hyper/hypoprolactinemia.4. Concurrent cardiac, hepatic, renal, or adrenal diseases.5. Presence of Cushing's syndrome.6. Use of ovulation-inducing drugs within the last three months.7. Use of insulin-stimulating medications within the last three months.8. Pregnant or breastfeeding women with infants under 6 months of age.9. Women planning to become pregnant within the next three months.10. Patient's withdrawal of consent to continue treatment.11. Occurrence of allergic reactions to the medications used in the study, particularly to the Apiaceae (Umbelliferae) family.

Design outcomes

Primary

MeasureTime frame
Incidence of menstrual bleeding and regularization of cycles. Timepoint: THREE menstrua cycles. Method of measurement: The study participants will be divided into two groups of 30: Group A (herbal intervention) and Group B (Dydrogesterone 10 mg). *Group A will receive an herbal formulation based on Aslaq (comprising Daucus carota* seeds, Mentha pulegium, and Vitex agnus-castus), with the dosage adjusted according to Persian Medicine (PM) pharmacopeia, administered in two divided doses for three weeks (starting from day 7 of the menstrual cycle). *Group B will be treated with Dydrogesterone (10 mg/day) during the last ten days of their menstrual cycle. The intervention in both groups will be repeated for three consecutive menstrual cycles. A follow-up will be conducted in the fourth month (without medication) to evaluate the incidence and regularity of menstruation. The Higham Chart (Pictorial Blood Loss Assessment Chart, PBAC) will be utilized to determine the volume of menstrual bleeding.

Secondary

MeasureTime frame
Menstrual bleeding volume, duration, and cycle length are considered *secondary outcomes. The changes in FSH, LH, Prolactin, TSH, Free Testosterone levels, and the LH/FSH ratio will be assessed and analyzed at both baseline and the end of the intervention. Furthermore, clinical improvements in hyperandrogenism symptoms, including acne and hirsutism (evaluated using the Ferriman-Gallwey score), will be recorded at the beginning and end of the study. Patient satisfaction with the treatment will be assessed at the end of the third month using the Visual Analogue Scale (VAS). Additionally, potential adverse drug reactions (ADRs) will be monitored and documented via a structured checklist. Timepoint: Three menstrual cycles per patient. Method of measurement: The changes in *FSH, LH, Prolactin, TSH, Free Testosterone levels, and the LH/FSH ratio will be analyzed at baseline and at the end of the intervention. Furthermore, clinical improvements in hyperandrogenism-related symptoms, specifically acne and hirsutism (evaluated via the Modified Ferriman-Gallwey (mFG) score), will be assessed at the beginning and end of the study. Patient satisfaction with the treatment will be measured at the end of the third month using the Visual Analogue Scale (VAS). Potential adverse drug reactions will be monitored and recorded using a structured checklist.Statistical Analysis:Qualitative data will be described using frequency tables, while quantitative data will be presented as mean ± standard deviation (SD) or median (interquartile range, IQR). Data normality will be assessed using the Kolmogorov-Smirnov (K-S) test. For the comparison of qualitative variables, the Chi-square test or Fisher's exact test will be employed. To compare quantitative data between the two groups, the Independent T-test or Mann-Whitney U test will be utilized. If the sample size is sufficient, Analysis of Covariance (ANCOVA) or logistic regression will be used to control for confounding factors, depending on the
