How IVF technology helps women over 40 to become pregnant
IVF technology is a kind of assisted reproduction technology, which helps infertile couples realize their reproductive dreams through in vitro fertilization, embryo transfer and other methods. For women over 40 years old, their fertility gradually decreases with age, and the probability of natural pregnancy is low. However, IVF technology provides an effective solution for these women. This article will elaborate on how IVF technology can help women over 40 to become pregnant from four aspects: in vitro fertilization, egg freezing, genetic screening and pregnancy security.
1. In vitro fertilization
In vitro fertilization is one of the core steps of IVF technology, which can effectively solve the difficulties of natural pregnancy for women over 40 years old. In vitro fertilization (IVF) combines sperm and egg in the laboratory to form a fertilized egg. After the fertilized egg is cultured to the appropriate stage of embryo development, the embryo is transferred into the female uterus. Because the quality of eggs of women over 40 years old has declined and the success rate is low, more in vitro fertilization attempts are needed. This technology can improve the probability of fertilized egg formation, and the success rate is also high.
Compared with natural pregnancy, IVF can help women over 40 years old to avoid the influence of age on the quality and quantity of eggs. In addition, IVF can also solve some infertility factors under special circumstances, such as male semen problems, female fallopian tube blockage, etc. Through in vitro fertilization technology, women over 40 years old can get a higher chance of pregnancy.
2. Egg freezing
The quality and quantity of eggs of women over 40 years old gradually decrease, and the probability of natural pregnancy is low. In order to deal with this problem, modern medicine can help these women retain their healthy eggs and delay the childbearing age by using the egg freezing technology in the IVF technology. Eggs are frozen by collecting fresh eggs, storing them with special freezing technology, and then thawing when necessary for in vitro fertilization.
The egg freezing technology provides more reproductive options for women over 40 years old. They can freeze high-quality eggs in their youth, delay the reproductive age and reduce the risk of pregnancy. With the continuous development of freezing technology, successfully thawed eggs can achieve the same fertility as fresh eggs, providing more possibilities for women over 40 years of age to become pregnant.
3. Genetic screening
Embryos conceived by women over 40 have a higher incidence of chromosomal abnormalities, such as Down syndrome and other genetic diseases. The embryo genetic diagnosis technology in the IVF technology can analyze the chromosome karyotype of the embryo, screen the embryo with abnormal chromosome, and improve the success rate of embryo transfer.
There are two main methods of embryonic genetic diagnosis, namely, preimplantation genetic diagnosis (PGD) and postimplantation genetic diagnosis (PGS). PGD is mainly used to screen cases of known genetic diseases, while PGS can screen chromosome abnormalities of embryos.
Through genetic screening technology, doctors can evaluate the health status of embryos before transplantation, select healthy embryos with normal chromosomes for transplantation, reduce the risk of abnormal fertility of women over 40 years old, and improve the success rate of IVF.
4. Pregnancy insurance
IVF technology is also very important for women over 40 years old to ensure pregnancy. Once successfully pregnant, these women need more careful pregnancy management and stronger medical support.
In order to ensure the safety and smooth progress of pregnancy, the hospital will provide more professional medical services for women over 40 years old, such as more frequent prenatal examinations, monitoring the growth and development of the fetus, and timely finding and handling pregnancy complications.
In addition, the hospital will also give guidance to women over 40 years old on pregnancy diet, physical activity, psychological adjustment and other aspects to help them overcome various difficulties and challenges during pregnancy.
To sum up, IVF technology helps women over 40 realize their dreams of pregnancy through in vitro fertilization, egg freezing, genetic screening and pregnancy security. These technologies not only improve the fertility opportunities of women over 40 years old, but also reduce the fertility risks, bringing more possibilities to these women.
