Polycystic ovary syndrome, or PCOS for short, is a common endocrine metabolic disorder in women of reproductive age and has a high prevalence of 8-12%. Many of the infertility patients I regularly encounter in the clinic are suffering from this disease. As a doctor, I encounter a group of patients with many similarities, such as: obesity, menstrual disorders, mostly manifested as delayed menstruation or even amenorrhea, hirsutism, acne on the face, and a history of spontaneous abortion. Of course, due to both environmental and genetic factors, there are many differences, such as: thin polycystic patients, patients with only high androgen and ultrasound ovarian polycystic-like changes, but very regular menstruation. These patients have a great confusion and are the ones who want to come to the hospital and have their doctors definitely fix their irregular periods. The ideal is good, but because the cause of this disease is unknown, our current treatment methods vary according to the patient’s needs and require symptomatic treatment. 1. Do not expect to be able to get your doctor to adjust your periods to normal before you get pregnant, this is not realistic and not necessary; 2. Tell your doctor your main needs: for example, I currently have no requirement to get pregnant, so we just need to adjust my periods to monthly or every 2 months, either with birth control pills (Daimler-35 or Mafron or Eusebio) or with progesterone ( The main purpose is to prevent endometriosis; if my main purpose is to get pregnant, then tell the doctor, the doctor will use the contraceptive pill to adjust the hormone to normal levels, and then use ovulation drugs to promote ovulation treatment, many patients can achieve the purpose of pregnancy, but…, must have patience, not only the patient, but also the doctor with ovulation drugs, need to have patience; 3. Patients who are overweight should actively lose weight, which is better than taking any medication, exercise more and eat less calorie-rich food, many patients can lose weight and control their weight to help them get pregnant and help reduce the miscarriage rate; 4. There are a lot of polycystic patients in the clinic who got pregnant easily, but the embryo stopped or miscarried because of insufficient luteal function, which is a pity. I hope what I wrote can help you. I wish every patient a speedy recovery and a good pregnancy!
