Concept and background of the third generation of IVF
IVF is a kind of baby developed by artificial assisted reproduction technology, in which sperm and egg are fertilized and combined in an in vitro culture room, and then the fertilized egg is implanted into the mother's uterus. IVF technology is widely used, which not only solves some reproductive problems, but also brings good news to those couples who cannot conceive naturally. With the continuous advancement of science and technology, IVF technology has also continued to develop, entering the third generation of IVF stage.
The third generation of IVF is a technology that has been improved and innovated on the basis of the second generation of IVF technology. The second generation of IVF mainly achieved pregnancy by implanting embryos into the mother's uterus. The third generation of IVF uses more accurate screening and culture technology to improve the success rate of pregnancy.
Flow of the third generation IVF
The process of the third generation IVF generally includes the following steps:
The first step is superovulation, that is to promote ovarian development and collect multiple follicles through drugs. This can increase the number of fertilized eggs and improve the success rate.
The second step is egg collection. After certain cultivation and preparation, doctors will collect mature eggs from women's ovaries through surgery.
The third step is sperm processing. Doctors will collect semen from men and extract sperm for preparation by centrifugation and other methods.
The fourth step is in vitro fertilization. The collected eggs and sperm are fertilized in vitro in a culture dish to form a fertilized egg.
The fifth step is embryo culture. The fertilized egg will be cultured in a petri dish until an embryo is formed.
The sixth step is embryo transfer. Doctors will choose the most promising embryos to transfer to the mother's womb, waiting for pregnancy.
Time required for the third generation IVF
The time required for the whole process of the third generation IVF will vary depending on individual differences and the actual situation of the hospital. But generally speaking, the whole process takes about 4-6 weeks.
During ovarian hyperstimulation, women need to receive medical treatment for a period of time, usually lasting 7-14 days. The egg collection operation needs to be carried out a few days before female ovulation, and the operation time is relatively short, usually about 30 minutes. Sperm processing, in vitro fertilization and embryo culture generally take 3-5 days. Finally, embryo transfer requires a simple operation, and the operation time is generally between 15-30 minutes.
In the whole process, the most critical stage is embryo culture and transfer. Through the improvement of the third generation IVF technology, doctors can more accurately screen and culture embryos, and improve the success rate of pregnancy. However, because each individual's situation is different, the success rate will also be different.
Summary
The third generation of IVF is an artificial assisted reproduction technology based on the second generation of IVF technology. The process includes superovulation, egg collection, sperm treatment, in vitro fertilization, embryo culture and embryo transfer. The whole process takes about 4-6 weeks, and the most critical step is the embryo culture and transfer stage. Through the application of the third generation IVF technology, doctors can improve the success rate of pregnancy and bring good news to those couples who cannot conceive naturally. However, due to the different circumstances of each individual, the success rate will still be different, which needs to be conducted under the guidance of professional doctors. With the continuous breakthrough of science and technology, the future fourth generation IVF technology may further improve the success rate and provide convenience for more couples to achieve their reproductive aspirations.
