Many mothers-to-be have mixed emotions when it comes to conceiving a baby, from the joy of being “upgraded” to becoming a mother to the worry of ensuring a healthy birth. In recent years, whether we see and hear, or happen around us to let us personally feel, is that the “birth control army” is growing. It is reasonable to say that now the conditions are much better than the parents generation, mothers and mothers-in-law in their daughters-in-law after the pregnancy will be changing ways to give them more nutrition, why are people now so “fragile”? This issue of the article we will talk about the reasons for this problem! 1, age is the key factor The age of pregnancy is an important factor in the increase in the number of birth control. In the past, the majority of women’s first pregnancies were between the ages of 23 and 28, but now it is not uncommon for women over 35 to have their first pregnancy, and there are even pregnancies in their early forties. Have you ever been pushed by your elders to have a baby? They always say that if you don’t take advantage of it now, you will not be able to have a baby later. This statement not only contains the care of your elders, but also contains some scientific truth. Because a woman’s fertility declines rapidly after the age of 35, even though some women now have a well-maintained appearance and still look like young girls in their 20s in their 30s, which is something to be thankful for, but our bodies do not lie, ovarian function continues to decline after the age of 35, so even if you have a childlike face can not make up for the fact that your ovaries are in decline. As we all know, pregnancy requires a “good” egg, which is produced by the ovaries, and the probability of infertility not only skyrockets after the age of 35, but the risk of pre-eclampsia also increases greatly even if conception is successful. Therefore, it is best for senior pregnant women to do a comprehensive pre-conception checkup before getting pregnant, and also to regularly test blood hormone levels and thyroid function after pregnancy, and if abnormalities are found, timely medication needs to be given high priority. 2, stress, too much pressure In today’s competitive world, stress is something that everyone can not avoid. Too much stress can lead to endocrine disorders, which can cause preterm abortion. Therefore, the population of birth control “white-collar”, teachers are common, rural pregnant women are rare, a large reason is because the first two work at a fast pace, mental stress. The first principle is to rest in bed after a pre-eclampsia miscarriage, and it is very important for pregnant women with pre-eclampsia miscarriage to take good psychological care. Pregnant women may have bad emotions such as anxiety, fear and tension due to pre-miscarriage, which may accelerate miscarriage. As pregnant women should not be frightened and overly mentally stimulated, family members should cooperate and not let pregnant women get angry and sad, they should make pregnant women emotionally stable and mentally happy. The incidence of pre-eclampsia miscarriage after conception through artificial insemination, in vitro fertilization – embryo transfer and other assisted reproductive technologies is higher than that of natural conception. 1988, the first IVF baby was born in the Third Hospital of Peking University on the mainland, and since then IVF has brought hope to many infertile families, but according to relevant statistics, by 2013, there have been In China alone, more than 500,000 IVF cycles were performed in one year, and in that year, the number of newborns in the country was about 16.4 million, and considering the success rate of IVF cycles, almost 1 out of 500,000 newborns was an “IVF baby”. The number of births in the country in that year was about 16.4 million, and considering the success rate of IVF cycles, about 1 in 500,000 births was an “IVF baby. Women who conceive through embryo transfer generally have blood tests drawn on the 12th day after the embryo transfer, and those whose early test results are not ideal are often aggressively placed on birth control. Couples performing assisted reproductive technology were originally unable to take the road to natural conception for various infertility reasons, and these causes of infertility are often factors of pre-eclampsia. 4, too many uncertainties Electromagnetic radiation, air pollution, etc. can lead to a decrease in the quality of eggs and sperm, and a decrease in the quality of embryos resulting in an increase in pre-eclampsia miscarriages. Finally, we remind all pregnant mothers-to-be not to work too hard during pregnancy, and if symptoms of pre-eclampsia miscarriage such as vaginal bleeding, lumbago and abdominal pain appear, they must go to the hospital in time. Fertility preservation is a race against time, and the earlier it is detected, the better the treatment.
