Detailed questioning is the key to the diagnosis and treatment of infertility. We must be sincere and patient, clear the patient’s tension and concern, and induce the patient to give a comprehensive and detailed medical history. In addition to the general medical history, special attention should be paid to the following: 1. Menstrual history including age of menarche, menstrual cycle, menstrual volume, duration, accompanying symptoms and the first day of the last menstrual period, etc., which are important for the diagnosis of ovulation, endometriosis or inflammation. 2. Marital history Age of marriage, number of marriages, history of contraception and the method and time of contraception, etc. 3.Previous pregnancy history Any history of miscarriage (including abortion), premature delivery, stillbirth; for those who have given birth at full term, we should know whether there are any abnormalities during pregnancy, delivery and postpartum, such as whether there is difficult delivery, postpartum bleeding, etc. We should also know about lactation. 4. Sexual history Pay attention to the frequency and duration of sexual life, the relationship with ovulation, and the presence of sexual life disorders and abnormal sexual desire. 5. Past medical history: To know whether there is mumps, measles, scarlet fever, tuberculosis, schistosomiasis, metabolic endocrine diseases, vaginitis, etc.; to know whether there is malnutrition; to pay special attention to the history of surgery, such as appendicitis, intestinal obstruction, ectopic pregnancy, etc.; to know whether there is a history of abortion and other uterine operations. The time and place of surgery and the special circumstances before and after surgery should be recorded. 6, family history The presence of congenital and hereditary diseases, to understand the fertility of both parents and siblings in pregnancy. 7.Relationship between weight gain or loss and sexual desire Understand the change of weight, body shape and sexual desire. 8.Occupation, family and hobbies Understand the nature of occupation, labor intensity, whether there is exposure to radiation or chemical toxins, and whether there are hobbies such as smoking and alcohol. 9.
