Diversity of assisted reproductive selection
With the continuous progress of science and technology, assisted reproductive technology plays an important role in solving fertility problems such as infertility. In addition to IVF, there are many other assisted reproductive options, such as artificial insemination, frozen embryo transfer, embryo screening, and so on. This article will elaborate on these aspects one by one.
1. Artificial insemination
Artificial insemination is a common assisted reproductive technology, which is applicable to sperm abnormalities caused by male reproductive system diseases or infertility caused by female reproductive system diseases. This technology increases the probability of pregnancy by directly injecting treated and selected sperm into the uterus of women. For example, the Reproductive Medicine Center of Peking Union Medical College Hospital in Beijing, China, provides artificial insemination services. Through the cooperation of professional teams, it has helped many couples successfully achieve a healthy birth.
Artificial insemination technology can be divided into two ways: family artificial insemination and hospital artificial insemination. Domestic artificial insemination refers to the self conducted by the husband and wife. After purchasing medical semen, they use syringes and other tools to inject semen into women's uterus. Hospital artificial insemination is carried out in the hospital, and doctors will inject semen into the uterus through a long tube at an appropriate time. Although the artificial insemination technology is relatively simple, it also needs the guidance of professional doctors and strict operating procedures to ensure safety and effectiveness.
Artificial insemination is a low risk, low-cost assisted reproductive technology, which has a good effect on infertility caused by some sperm abnormalities or unknown reasons. It can be used as an alternative to assistive technology to help infertile couples improve their chances of pregnancy.
2. Frozen embryo transfer
Frozen embryo transfer is an assisted reproductive technology to realize pregnancy after in vitro fertilization by freezing and preserving the surplus fertilized eggs, thawing and implanting them into the female uterus at an appropriate time. The Assisted Reproduction Center of Peking Union Medical College Hospital provides frozen embryo transfer services, by placing frozen implanted embryos in the uterus of patients to make them pregnant. This technology can maximize the use of high-quality embryos and improve the pregnancy rate.
Frozen embryo transfer technology can solve a problem faced by infertile couples in vitro fertilization, that is, how to deal with the surplus fertilized eggs. By cryopreservation, these fertilized eggs can be thawed and implanted into the uterus of women at the right time, increasing the probability of pregnancy. In addition, frozen embryo transfer technology can also solve the problem that some patients cannot immediately carry out IVF for various reasons, thus giving them more choices and opportunities.
3. Embryo screening
Embryo screening is a technology that detects genes and chromosomes of embryos to screen out embryos carrying certain genetic diseases or chromosome abnormalities, and select healthy embryos for transplantation. This technology can avoid the transmission of some genetic diseases and embryo termination caused by chromosome abnormalities, and improve the success rate of pregnancy. The assisted reproduction center of Peking Union Medical College Hospital also provides embryo screening services to select the healthiest embryos for patients by screening their embryos.
Embryo screening technology has a wide range of applications. It can detect most common genetic diseases and chromosomal abnormalities, such as Down syndrome, blastocysts, etc. Screening can not only reduce the occurrence of genetic diseases and the risk of disease, but also improve the quality and success rate of embryo transfer.
four
It is a kind of assisted reproductive technology that uses the uterus of other women as a container to receive fertilized eggs and implant them to conceive the fetus. Although it is prohibited by law in China, technology has been widely used internationally. Some internationally renowned assisted reproductive hospitals, such as reproductive medicine specialist hospitals in the United States and centers in Thailand, provide services.
The technique is mainly applicable to couples with abnormal uterus, no uterus or serious health problems. By implanting the fertilized egg into the uterus of other women, they can become pregnant and give birth to a healthy baby. Although technology has played a positive role in solving the problem of infertility, it also has some legal and ethical disputes. Therefore, careful consideration should be given to the choice.
Summary
In addition to IVF, modern medicine also provides a variety of assisted reproductive options. Artificial insemination, frozen embryo transfer, and embryo screening are all common assisted reproductive technologies. These technologies have a wide range of applications and can help many infertile couples achieve their fertility aspirations. However, each technology has its indications and risks. Therefore, when choosing assisted reproductive technology, a reasonable decision should be made according to personal conditions and doctors' suggestions.
