According to data released by the National Health and Planning Commission at the end of September: since China’s full liberalization of the two-child policy on 1 January this year, the national maternal mortality rate in the first half of the year has been on an upward trend, reaching 18.3 per 100,000 live births, an increase of 30.6 per cent over the same period last year. Although some scholars have pointed out that maternal deaths are mainly in the perinatal period, and children after the liberalization of the two-child policy will not be born until the end of the year, so the increase in the maternal mortality rate in the first half of the year has nothing to do with the full two-child. However, with the liberalization of the two-child policy, in addition to the obvious shortage of medical resources, mothers of two children themselves are facing great challenges. Whether you can fulfill your own wishes or the expectations of your mother-in-law, but also depends on the following 7 major difficulties you can successfully pass. 1, too old “old” is the first problem. The best age for women to have children is 21-30 years old, and the curve of fertility from the age of 30 years old is on a downward trend. 35 years old when fertility declined to only equal to 50% of 25 year old women, 38 years old to 25%, over 40 years old is less than 5%. Some women even lose their fertility 7-8 years before menopause. 2, the decline of ovarian reserve The primordial follicles contained in the ovarian cortex of human females are called ovarian reserve. At the birth of a baby girl, there are enough eggs stored in the ovaries to last a lifetime. When a girl enters puberty, every 28 days or so, there will be 1 (rarely 2) primary oocytes stimulated by sex hormones to wake up, develop and mature into eggs, and be discharged. With age, women’s ovarian reserve function declines, the number of sinus follicles decreases, and follicle stimulating hormone (FSH) values rise, leading to a decrease in the ability to ovulate. 3, the quality of the egg is reduced The age of the egg is basically the same age as the age of the person, the later the age of fertility, the older the egg, the greater the impact of the egg by the environment and pollution, the quality of the egg cell is also the worse. Not only are eggs prone to chromosomal abnormalities, which can lead to the birth of deformed children, but also increase the chances of fetal arrest and miscarriage. For example, the incidence of congenital trisomy 21 will increase exponentially with the age of the pregnant woman. Medical research predicts that the incidence of trisomy 21 will increase from 0.11% at the age of 25-29 to 0.26% at the age of 30-35, and to 0.56% at the age of 36-40. 4, the endometrium is too thin Fertilized eggs in the endometrium is the beginning of the conception of the embryo, but with the increase in age, the endometrium in the form and function of a series of changes will occur. As a woman approaches menopause, the lining of the uterus may become thinner and less suitable for a fertilized egg. As the saying goes, “no good crop grows in saline soil”. In addition, the vaginal secretions will become less fluid, also not conducive to sperm entry. 5, complications due to older, second-trimester pregnant women in many people may have a slight diabetes or hypertension, usually normal body functions, did not realize. Once pregnant, changes in body functions and hormone levels will induce these hidden diseases, not only affect the normal development of the fetus, but also bring life-threatening risks to pregnant women. 6, work, life stress Generally this stage of the female, after the struggle of the early struggle, career is in a good time to flourish. The pressure of work, coupled with the “old, young” family status, so that many women are physically and mentally exhausted. Long-term overwork, accompanied by insomnia, tension, anxiety, many women doubt their ability to have the energy to take advantage of a policy. 7, he can still cooperate with it Although men’s fertility is a little stronger than women, but they are after 35 years old sperm quality will also decline day by day. Although there are many cases of old married couples, there are also men who are still fertile even at the age of 60 or 70, but the quality of his sperm has greatly declined compared to when he had his first child. Therefore, mothers of two children should not only pay attention to their own pre-pregnancy conditioning, but also make sure to ask their husbands to join them and go to relive the blissful beauty of pregnancy tests together. The difficulties faced by elderly second-born mothers are numerous, and here is also a reminder to everyone, do not think that you have already given birth to a child, now must be no problem. Emphasizing pre-pregnancy testing and scientifically preparing for pregnancy with a positive mindset is key!
