The characteristics of polycystic ovary syndrome include amenorrhea, obesity, infertility, acne, hirsutism, and hormone level tests generally indicate high testosterone, high luteinizing hormone, and low estrogen levels. Therefore, dietary intake should avoid large portions of meat, high-fat, and high-calorie foods. It is beneficial to consume more vegetables and fruits, and foods that are high in estrogen levels, such as beans and soy products, especially soy milk made from black soybeans. Besides pharmacological treatments, it is crucial for patients with polycystic ovary syndrome to regulate their daily routines and diet. If a patient is significantly overweight, it is essential to lose weight through exercise.
