Does 35 year old childbearing affect embryo quality?

With the development of modern society, more and more women choose to postpone childbearing, that is, they begin to conceive and have children around the age of 35. However, people often hear that postponing fertility has an impact on embryo quality. So, will the birth at the age of 35 really affect the embryo quality? This article will elaborate on the physical condition, egg quality, chromosome abnormalities and maternal health.

Physical condition

Although everyone's physical condition varies from person to person, the growth of age will lead to some physiological changes in women, which may affect the quality of embryos. After 35 years old, women's ovarian function begins to decline, and the number and quality of follicles will decrease. In addition, the uterine environment of women will also change with age, including the thickness of endometrium and blood supply. These changes in physical conditions may have an impact on the quality of embryos.

For example, a study conducted in a hospital in Shanghai, China, found that women over 35 years old had low embryo quality scores and low embryo implantation rate during in vitro fertilization (IVF). This result implies the influence of age on embryo quality.

However, it is worth noting that physical condition is only a factor, and it is not the only factor that determines the quality of embryos. Other influences also need to be considered.

Egg mass

With the growth of age, the quality of female eggs will gradually decline. After the age of 35, the number of female eggs decreases, and eggs may carry more chromosomal abnormalities. This means that the probability of chromosomal abnormalities in the embryos of women over 35 years old will be relatively high, which will increase the risk of pregnant healthy babies.

A study conducted in the United States shows that the quality and quantity of eggs of women over 35 years old have declined significantly, leading to a decrease in the success rate of in vitro fertilization. This also shows the influence of egg quality on embryo quality.

In addition, data from a hospital shows that the probability of chromosomal abnormalities in women under 35 years of age during childbirth is 10% to 20%, while that in women over 35 years of age will increase to 30% to 60%. This again confirmed the influence of age on egg quality and embryo quality.

Chromosomal abnormality

The risk of women carrying chromosomal abnormalities increases with age. Chromosome abnormalities can lead to abortion, birth defects and other problems. Women over 35 years old have a relatively high probability of carrying embryos with chromosomal abnormalities, which has a direct impact on the quality of embryos.

Research data show that the rate of abnormal chromosome embryos in women over 35 years old has significantly increased. A study conducted in the United States found that women under 35 years old have a 5% chance of chromosomal abnormalities, while women over 35 years old have a 20% chance. This result shows that age has a significant impact on the risk of embryo carrying chromosome abnormalities.

Health of pregnant women

In addition to affecting the quality of embryos, women over 35 years old also face the risk of maternal health during pregnancy. For example, older pregnant women are more likely to suffer from complications such as gestational diabetes and hypertension, which may affect the development and health of embryos.

In recent years, the data from a hospital showed that the risk of gestational diabetes and hypertension in women over 35 years old during pregnancy was significantly increased. These complications may lead to problems such as overweight and premature delivery of the baby, and then affect the quality of the embryo.

summary

To sum up, childbearing at the age of 35 does have an impact on embryo quality. From the aspects of physical condition, egg quality, chromosome abnormalities and maternal health, women over 35 years old may face more difficulties and risks in pregnancy, and the quality of embryos will also be affected. Therefore, it is suggested that women should plan their childbearing as soon as possible to ensure the quality of embryos and the health of pregnant women.
