1. Decline of reproductive capacity
With the growth of age, women's reproductive capacity will gradually decline. Most women's egg quality and quantity will decline significantly after the age of 40, leading to increased difficulty in childbirth. According to statistics, the success rate of 46 year old women's natural pregnancy is about 1%.
First of all, the quality of female eggs will decline after the age of 40, and the formation and development ability of fertilized eggs will be weakened, leading to an increased risk of implantation failure. Secondly, after the age of 40, the number of follicles in women's ovaries will become less and less, the follicles will develop slowly, and the frequency of releasing eggs will also be reduced, reducing the chance of pregnancy. In addition, elderly women have a high probability of suffering from various chronic diseases, such as hypertension, diabetes, etc. These diseases will affect the intrauterine environment and reduce the probability of successful pregnancy.
Therefore, 46 year old women do not have a high chance of natural pregnancy and need the help of assisted reproductive technology.
2. Application of assisted reproductive technology
For women over 45 years old, the opportunity to have children mainly depends on assisted reproductive technology, such as IVF technology. In vitro fertilization (IVF) is a technology that can culture the fertilized eggs to the embryonic stage, and then transfer the embryos to the mother's uterus.
The success rate of IVF mainly depends on many factors, including female age, egg quality, uterine environment, etc. Although age has a certain impact on the success rate, the continuous progress of modern medical technology enables even older women to achieve fertility through IVF technology.
According to the statistics of a famous hospital in China, many women around 46 years old have successfully given birth through IVF technology every year, with a success rate of about 20%. This shows that although the probability of natural pregnancy is low, 46 year old women still have a considerable chance to achieve their reproductive aspirations through assisted reproductive technology.
3. Health risks of elderly mothers
Although the probability of elderly mothers giving birth exists, it should be noted that there are certain health risks associated with elderly mothers giving birth.
First, the older you are, the higher the risk of pregnancy complications such as gestational diabetes mellitus and pregnancy induced hypertension. These complications will cause some harm to both mother and fetus.
Secondly, the older the pregnant woman, the higher the risk of genetic defects and chromosomal abnormalities. For example, about 9% of pregnant women have abnormal chromosomes.
In addition, 46 year old women may face greater risks during pregnancy and childbirth after giving birth, such as increased risks of premature delivery, low birth weight, and delivery complications.
4. Age selection and family planning
Faced with the uncertainty of the fertility rate of the 46 year old and the existence of health risks, women should make rational choices in family planning.
First of all, women should plan their childbearing in advance and should not postpone it to a higher age. When young, women are most fertile, and the quality and quantity of eggs are relatively good.
Secondly, women should consult with professional doctors when choosing to give birth and evaluate their own fertility. Doctors can evaluate from many aspects, including the number of follicles, egg quality, gynecological diseases, etc.
At the same time, women can also choose to use frozen eggs and other assisted reproductive technologies to provide better protection for future fertility.
Summary
The probability of childbirth at the age of 46 is low, and the success rate of natural pregnancy is about 1%. However, through assisted reproductive technologies such as IVF, 46 year old women still have considerable opportunities to achieve fertility. However, older mothers need to be aware of health risks, including increased risks of pregnancy complications and fetal chromosomal abnormalities. Therefore, women should plan their childbearing in advance, consult with professional doctors, and assist reproductive technology to freeze eggs in advance, so as to provide better guarantee for future childbearing.
