When encountering infertility problems, many people are torn between being sick and not sick, seeing or not seeing, and treating or not treating, even those with a medical background. Some people are so desperate that they look at the doctor to find the disease and suspect the disease, leading to excessive examination and treatment. Some people are insensitive, “teenage” ambition does not say worry, there is a disease to avoid the disease does not see the doctor, find their own reasons for blind optimism, lost the best time to have children. The best age for people to have children is just over 10 years, such as no extremely special circumstances, at what age should do things. Especially in fertility issues, it is necessary to identify problems in time to solve them. In the following, we will talk about how to conduct self-examination for infertility and determine whether you need to go to the hospital for further treatment through self-examination. 1.Time to try to conceive Couples who have normal sexual life without contraception for one year and fail to conceive are diagnosed with infertility. If the couple is often separated, the time of trying to conceive can be extended to 2 years appropriately. Normal sexual life is generally 2~3 times a week. Therefore, for couples who have been trying to conceive for less than 1 year, they need not be too nervous and just relax. 2. Age Infertility is a disease closely related to age within a certain range. As age increases, the incidence of female infertility increases and fertility decreases. When it comes to fertility, younger people can be capricious, while older people need to be stupid birds first. If a 25-year-old infertility patient is hesitant to accept the treatment proposed by her doctor and hesitates, I can give her 5 years to think about it. For a patient who is 35 years old or older, early intervention and aggressive treatment is the best policy. 3. Menstrual condition Generally speaking, normal menstruation indicates normal endocrine function and normal ovulation. The normal menstrual cycle is 25~35 days and the period is 3~7 days. If menstruation is irregular, too much or too little, it may affect ovulation leading to infertility. Occasional changes in the menstrual cycle do not need to be too stressful, and excessive concern may instead affect the regularity of menstruation. Menstrual changes may also occur in healthy women, especially when there are large emotional swings. In addition, special attention should be paid to the presence of dysmenorrhea, which is also often associated with infertility. 4. Past medical and surgical history Previous endocrine diseases and autoimmune diseases, such as thyroid disease, diabetes, rheumatoid arthritis and systemic lupus erythematosus, are associated with infertility. Previous history of pelvic and abdominal infections and surgeries, such as pelvic abscess, appendicitis, pelvic and abdominal tuberculosis, pelvic inflammatory disease, intestinal obstruction, endometriosis, ectopic pregnancy, cesarean section, abortion, etc., may affect the function of the fallopian tubes and lead to infertility. 5, weight Weight is one of the important signs of a person’s health status. Both being too fat and too thin are detrimental to fertility. Abnormal weight is often associated with endocrine disorders, some of which manifest as irregular menstruation, scanty menstruation, or even amenorrhea. Medical science is based on body mass index. Body mass index (BMI) = weight (kg)/height (m) squared. The normal BMI is 18~25, 25~30 for overweight, >30 for mild obesity, >35 for moderate obesity and >40 for severe obesity.
