Advances in medical technology for older babies
With the development of society, more and more women choose to conceive and give birth at an advanced age. However, with the growth of age, women's reproductive system function will decline, and the chance of natural pregnancy will be greatly reduced. In order to meet the needs of these women, the medical field has made continuous progress and developed many technologies to give birth at an advanced age. Next, we will introduce the progress of medical technology in elderly childbearing from different perspectives.
1. In vitro fertilization technology
In vitro fertilization (IVF) is one of the commonly used methods in assisted reproductive technology (ART), which provides older women with opportunities for pregnancy and childbirth. In IVF technology, doctors will take eggs from women in vitro and fertilize them with male sperm in the laboratory. The fertilized egg is then incubated in a petri dish for several days until it develops into an embryo. Finally, doctors transfer the embryo back to the female uterus to achieve pregnancy.
In recent years, in vitro fertilization technology has made many breakthroughs. First, doctors can select sperm with good genetic background and high development potential through ICSI (single sperm injection) technology. Secondly, doctors can use PGD (embryo gene diagnosis) technology to carry out gene detection on the fertilized eggs to screen out embryos without genetic diseases and improve the success rate of pregnancy. The introduction of these technologies provides more choices for older women to achieve fertility.
2. Egg freezing technology
With the growth of age, the number and quality of women's eggs will decline, and the difficulty of natural pregnancy will also increase. Therefore, some elderly women will consider freezing eggs to preserve young eggs and use them when necessary.
The current egg freezing technology is very mature, which can ensure the integrity and availability of eggs after thawing. In the process of freezing eggs, doctors will take out the eggs through thin tubes guided by ultrasound, and then store them with special liquids in the laboratory. When a woman is ready to become pregnant, the doctor will thaw the egg and fertilize it with sperm, and finally transplant the fertilized egg back to the uterus.
The egg freezing technology provides older women with a longer choice. They can decide when to have children according to their own wishes, which improves the chance of natural pregnancy.
3. Surrogate technology
For some elderly women, due to health reasons or other reasons, they are unable to conceive and give birth. At this time, surrogacy technology provides them with a choice to have their own children.
Surrogate technology refers to the transfer of a woman's fertilized egg into another woman's uterus, so that she can be pregnant and give birth on her behalf. During this process, the doctor will transfer the fertilized egg into the womb of the surrogate through in vitro fertilization or transfer technology, and she will be responsible for the pregnancy and delivery of the child. This technology provides hope for women who cannot conceive and gives them the opportunity to become mothers.
4. Pre embryo transfer genetic screening technology
For some elderly women, the pregnancy success rate is low due to the decline of the reproductive system and the decline of the quality of embryonic development. In order to improve the success rate of pregnancy, medical technology has introduced the pre embryo transfer genetic screening technology.
This technique allows doctors to perform genetic tests on embryos before they are transferred back to the uterus to exclude embryos carrying genetic diseases or chromosomal abnormalities. By selecting high-quality embryos for transplantation, the risk of abortion is reduced and the success rate of pregnancy is improved.
summary
With the continuous progress of medical technology, it has become possible to have babies at an advanced age. In vitro fertilization technology, egg freezing technology, surrogacy technology and pre embryo transfer genetic screening technology provide older women with more choices. These advances have brought hope and opportunities to women who wish to conceive and give birth at an advanced age.
