This cross-sectional study aims to compare the effectiveness of oral contraceptives, oral progesterone (didrogesterone), and inositol in regulating menstrual cycles among women diagnosed with polycystic ovary syndrome (PCOS). PCOS is a common endocrine disorder affecting reproductive-aged women and is associated with menstrual irregularities, hyperandrogenism, and polycystic ovarian morphology. While oral contraceptives are the mainstay of treatment, their use may be contraindicated in patients with cardiovascular risk factors, liver dysfunction, or in those who desire pregnancy. This study investigates whether oral progesterone and myo-inositol can serve as effective and safer alternatives for menstrual regulation and improvement of ovarian morphology and hyperandrogenic symptoms. A total of 150 women aged 15-40 years with a diagnosis of PCOS will be enrolled and divided into three equal groups: Group 1: Oral contraceptive users Group 2: Oral progesterone users Group 3: Inositol users The study will assess changes in menstrual regularity, ovarian morphology (via ultrasound), and clinical features such as hirsutism and acne before and after treatment.
