The family planning policy is gradually relaxed, many eligible families can have a second child, so more people are concerned about the considerations of having a second child at an older age. For
For older couples over 35 years old, welcoming a new baby is not so easy. In general, there are four difficult hurdles to overcome when having a second child at an older age.
Pregnancy is difficult;
Easy to miscarry;
Birth defects;
The risk of hemorrhage is high.
Therefore, older parents planning to have a second child should be prepared to face bad news.
Difficulty 1: Pregnancy is difficult
The chances of pregnancy for women over the age of 35 start to decline, and the cumulative chance of conception in a year is about 75%. Therefore, women over the age of 35 who are trying to conceive have no chance of conceiving after 6 months of active trying.
If you have not conceived after 6 months of active attempts, it is time to consult a fertility specialist.
Women over the age of 40 have a dramatic decrease in their ability to conceive, with a cumulative chance of conception of about 40% to 50% a year. At this age, even with in vitro fertilization (IVF), the pregnancy rate is only
10%. This is due to the fact that the number of normal egg cells in the ovaries of women over the age of 40 is greatly reduced. Therefore, women over the age of 40 who wish to become pregnant after 3 months of trying
If you have not conceived after 3 months of trying, you should seek the help of a fertility specialist.
For women over the age of 45, pregnancy is very difficult and the chances of conception are less than 1%. This is because almost all of the remaining eggs in women over 45 are genetically abnormal. Those who are over 45
Almost all successful pregnancies over the age of 45 are the result of donor eggs.
Difficulty #2: Prone to miscarriage
The miscarriage rate is about 15% in the population as a whole, with a gradual increase with age.
Pregnancies at age 35 have a miscarriage rate of about 25%;
At the age of 40, the miscarriage rate is about 35%;
At the age of 45, the miscarriage rate is already about 50% to 60%.
The main cause of miscarriage in older pregnancies is chromosomal abnormality of the embryo, so usually there is no point in fertility treatment to prevent the miscarriage from happening.
Difficulty 3: Many birth defects
As women age, the quality of their eggs declines and the probability of having problems with fertilized eggs rises significantly. This is only the probability of chromosomal abnormalities and does not include the higher incidence of fetal structural defects, which can be seen as a high risk.
Difficulty 4: High risk of hemorrhage
There are many advantages of normal delivery, such as less damage and faster recovery. The risk of hemorrhage is much lower for women who had their first child by normal delivery compared to women who had their first child by cesarean section. Therefore, the risk of hemorrhage mentioned here is mainly for women whose first child was delivered by cesarean section.
In China, there is no official cesarean rate, which is 46.2% according to a WHO survey in a sample of three Chinese provinces and cities. According to this analysis, the cesarean rate in large cities is higher than
50%. In other words, nearly half of the women who have a second pregnancy have a history of cesarean delivery. Once the placenta of these women is implanted in the lower uterine incision, it will become the so-called “dangerous placenta praevia”. The thought of these “time bombs” makes obstetricians sleepless. Because of the high probability of postpartum hemorrhage, severe cases require hysterectomy and may even lead to maternal death in some cases.
Summary
What about the risks of having a second child at an older age? You have to break through one level after another.
So, to have a baby, you have to take advantage of the early; want to have more births, the birth of good.
