What is IVF?

IVF, also known as assisted reproductive technology (ART), refers to the process by which couples who are unable to conceive naturally can achieve fertility through artificial assisted technology. This technology was first invented by Robert Edwards and Patrick Steptoe of the University of Edinburgh in 1978, and the world's first test tube baby was born successfully. Subsequently, the IVF technology gradually improved and developed, becoming the gospel of millions of infertile couples.

Steps of IVF technology

IVF technology is mainly divided into the following steps: 1. Ovulation promotion: The woman first receives hormone treatment to promote ovarian ovulation through drugs, so that multiple mature eggs can be discharged from the ovary at the same time. 2. Egg collection: under the ultrasonic guidance of the woman, the doctor uses a slender needle to empty mature follicles and collect eggs. 3. Sperm collection: The man provides fresh semen samples, or provides frozen semen through the semen bank, and then extracts the sperm through special treatment. 4. Fertilization: In the laboratory, the collected eggs and sperm are fertilized in vitro to make the sperm enter the egg. 5. Embryo culture: The fertilized eggs continue to be cultured in the laboratory to form embryos. 6. Embryo transfer: The doctor will select the embryo most likely to be implanted and insert it into the woman's uterus through the fallopian tube for embryo transfer. 7. Pregnancy test: After embryo transfer, the woman needs to observe for a period of time. If the fertilized egg is successfully implanted, there will be signs of pregnancy.

Common IVF technology

IVF technology covers a variety of methods, the most commonly used ones include: 1. In vitro fertilization embryo transfer (IVF-ET): fertilize eggs and sperm in vitro in the laboratory, cultivate them into embryos, and then transfer them to the woman's uterus. 2. Minimally invasive sperm injection (ICSI): This is a method of directly injecting single sperm into oocytes, which is applicable to the poor quality of male sperm. 3. Pre soaked embryo diagnosis (PGD): genetic testing is carried out by taking pre embryonic cells to screen chromosome and gene abnormalities, so as to select healthy embryos for transplantation.

Development and application of IVF technology

With the continuous development and improvement of IVF technology, more and more infertile couples have the opportunity to achieve fertility. At the same time, IVF technology also provides solutions to reproductive problems in other diseases and situations, such as polycystic ovary syndrome, fallopian tube blockage, male sperm quality problems, etc. Nowadays, there are many medical institutions specialized in IVF technology around the world, such as Mayo Clinic in the United States, Bourn Hall Clinic in the United Kingdom, etc. Conclusion: IVF is a method to help couples who cannot conceive naturally to achieve fertility through artificial assistance technology. The specific steps include: ovulation induction, egg collection, sperm collection, fertilization, embryo culture, embryo transfer and pregnancy detection. Common IVF technologies include IVF-ET, ICSI and PGD. The development and application of IVF technology provides hope for infertile couples and solutions to other reproductive problems. Professional medical institutions around the country also provided support for the promotion and implementation of this technology.
