Polycystic ovary syndrome (PCOS) manifests as absent or irregular menstrual periods, and is also associated with obesity, hirsutism, insulin metabolism disorders, as well as elevated blood sugar and cholesterol levels. The mechanism behind the development of PCOS is unclear but may be related to genetic factors, diet, and lack of exercise. Due to the irregular menstrual cycles, which stem from anovulation (lack of ovulation), the likelihood of pregnancy decreases. It is challenging to calculate the specific probability of pregnancy, but overall, the chances of becoming pregnant with PCOS are very low, although there is still a possibility. Treatment for PCOS generally starts with lifestyle changes, such as avoiding staying up late and refraining from eating sweets. Weight management is also crucial; weight gain is recommended for those who are underweight, whereas weight loss is advised for those who are overweight, along with appropriate exercise.
