1, if you take the market commonly used short-acting compound oral contraceptive pills, such as mafenac, yosmin, etc., stopping the drug after a menstrual period, you can consider preparing for pregnancy. 2.If you have placed an ordinary intrauterine device or a contraceptive ring containing medication, such as Mannuelle, you can consider getting pregnant after a period after removing the ring, and you don’t need to use contraception for 3-6 months as rumored by the rumor mill. 3, there has been an ectopic pregnancy of women, and then more than 90% of pregnancy can be pregnant in the uterus, if the operation goes well, recovery is normal, three months after the operation can consider getting pregnant again, not before pregnancy must be carried out hysterosalpingography. But once pregnant, the risk of ectopic pregnancy still exists, and higher than the general population, should be consulted as soon as possible to ask the doctor to determine the location of the embryo bed. 4. For women who have had a first-born cesarean section, considering the scarring on the uterus caused by the previous surgery, and the physical strength and energy that may be required to raise a second child, it is recommended that pregnancy be considered two years after the surgery. 5. Women with a history of cesarean section do not always have to have another cesarean section when they get pregnant again. They should consult their obstetrician if they can try to have a vaginal delivery. Women who want to give birth should pay attention to their teeth. If you do not have the habit of visiting the dentist regularly, it is recommended that you visit the dentist before you prepare for pregnancy to solve any dental problems that may have existed but have been neglected, and to have your teeth cleaned once. 7. Women with chronic diseases such as high blood pressure or diabetes must have their diseases stabilized under control, and then have their pregnancies fully evaluated by an internist/endocrinologist and an obstetrician/gynecologist, and decide whether to use contraception or not after they are fully aware of the risks of pregnancy. 8. Women over 35 should be aware of the fact that their chances of conception are significantly lower than those of the younger age group. The chances of conception for each menstrual cycle of women over 40 are only 1/100, and if they have not been pregnant after trying for 6 months, a more proactive approach would be to consult a specialist in reproductive medicine and receive the necessary medical assistance. 9. Pregnancy in women over the age of 35 is known medically as a high-risk pregnancy, and once successful conception has taken place, more attention should be paid to prenatal checkups. The risk of delivering a chromosomally abnormal fetus increases at an advanced age, and the risk of delivering a Down’s syndrome child is less than 1/1000 for a 25-year-old woman, 1/365 for a 35-year-old, 1/85 for a 40-year-old, and as high as 1/30 for a 45-year-old. 10, even if a woman over the age of 40 is in good health, she should also be routinely screened for high blood pressure and diabetes and other illnesses prior to conception. 11, advanced age is not an absolute indication of cesarean section, to determine the ability to deliver several major elements are as follows: strong force of birth, generous birth canal, not too large fetus, fetal prelude and pelvic position of the relationship. If all these conditions are present, the labor can be successful even in older pregnancies. Perineal massage can be performed during pregnancy to minimize the risk of severe tearing and lateral incision. 12. Older fathers appear to increase their wives’ risk of spontaneous abortion, certain autosomal dominant disorders, autism spectrum disorders, and schizophrenia. Counseling for these possible risks, albeit small, should be performed if the man is older than 40 years. 13. Among the causes of infertility, female factors account for 40-55%, male factors account for 25-40%, couple factors account for 20%, and immune and unknown causes account for 10%. Infertility needs to be investigated by both men and women, women see obstetrics and gynecology, men see male department, to find out the cause of infertility in order to target the treatment. Infertility and gynecology are both areas where over-treatment is rampant, so it is important to go to a regular hospital.
