What is the first generation of IVF?
In vitro fertilization (IVF) is a reproductive technology that promotes the fertilization of eggs, cultivates embryos, and then implants embryos into women's uterus to develop them into babies. The first generation of test tube babies refer to the first test tube babies successfully born, and their birth marks a major breakthrough in human reproductive medicine.
The concept of the first generation of test tube baby first appeared in the 1970s. In 1978, Robert Edwards and Patrick Steptoe of Cambridge University, England, successfully gave birth to the world's first test tube baby for an infertile couple. This breakthrough success led to the development of IVF technology, enabling thousands of infertile couples to achieve artificial assisted reproduction.
Precautions for IVF
As a complex reproductive technology, IVF requires couples to make necessary preparations and precautions before treatment. First of all, couples need to choose the right diagnosis and treatment team in normal hospitals or professional reproductive medical institutions. Secondly, couples need to undergo comprehensive physical examination and disease screening to ensure that they can withstand the physical conditions of IVF treatment. In addition, couples also need to understand and sign relevant consent forms, and be prepared and supported psychologically.
During the specific operation of IVF, couples need to follow the guidance and requirements of doctors. They need to take hormone drugs on time, regularly check the growth of follicles, and determine the most appropriate time for egg retrieval under the guidance of doctors. During fertilization and embryo culture, couples need to ensure good living habits and avoid smoking, drinking and overwork. Finally, after embryo implantation, couples need to follow the doctor's advice, pay attention to rest, and check whether there are any abnormal symptoms.
Success rate and risk of IVF
The success rate of IVF is one of the important indicators that couples pay attention to. According to medical statistics, the success rate of IVF is usually between 30% and 40%, and factors such as age, infertility cause and weight will affect the success rate. In addition, IVF will also face some risks, including multiple pregnancy, pregnancy complications, abortion, etc. Therefore, when choosing IVF technology, couples need to fully understand the success rate and risks, and make reasonable decisions according to their own conditions.
Development of the second generation of IVF
The second generation of IVF is based on the first generation of IVF technology, combined with more advanced assisted reproductive technology and research on interference factors, which has improved the success rate and safety of IVF. The development of the second generation IVF technology mainly includes the following aspects:
First of all, the operation steps and equipment of IVF technology have been improved more precisely and automatically, which has improved the operation efficiency and survival rate of eggs and embryos. Secondly, the development of gene screening technology enables couples to choose healthy embryos for implantation, reducing the incidence of chromosome abnormalities and genetic diseases. In addition, advances in embryo freezing technology have also provided couples with more time and opportunities for multiple IVF treatments.
To sum up, the birth of the first generation of IVF has brought hope to infertile couples and promoted the development of IVF technology. IVF treatment requires couples to carefully select hospitals and teams, and follow the doctor's instructions and precautions. The continuous development of the second generation IVF technology has further improved the success rate and safety. With the continuous progress of science and technology, it is believed that IVF technology will get greater breakthrough and improvement in the future.
