What is the third generation of IVF?
IVF, also known as artificial assisted reproduction technology, is a way to help couples who cannot conceive naturally achieve their reproductive aspirations. The first generation of test tube baby refers to the world's first test tube baby born in 1978 by Louisa Brown of Wales, England. The third generation of IVF is an advanced technology with higher success rate and less risk based on the first generation and the second generation, combined with the latest technological progress.
How to carry out IVF?
Artificial IVF mainly includes the following steps:
First, women receive ovulation guidance or pricking for eggs to increase the number of eggs. This process usually requires drug treatment to stimulate the ovary to produce more eggs.
Then, eggs are collected from the female body, usually through surgery or the placement of ovarian puncture needle, and eggs are taken under the guidance of ultrasound. This process is usually performed under general anesthesia to ensure maximum safety and comfort for the patient.
Next, sperm can be collected from the male body by hand or by testicular biopsy. Then, sperm and eggs are placed in an in vitro culture dish for in vitro fertilization (IVF) or oocyte microinjection (ICSI).
Finally, the fertilized eggs are transferred to the female uterus for embryo transfer. In this process, the fertilized eggs can be directly transferred into the uterus, or the embryos can be frozen and preserved first, and then transferred at the best time.
Progress in IVF technology
With the continuous progress of science and technology, IVF technology is also developing. Compared with the first generation and the second generation, the third generation IVF has made progress in the following aspects:
First of all, the new generation of IVF technology uses more sophisticated embryo screening and selection methods, improving the success rate of embryo transfer. By means of gene sequencing, chromosome screening and other means, the health status of embryos can be assessed, and the failure probability caused by abnormal embryos can be reduced.
Secondly, the third generation IVF technology has also introduced new assisted reproductive technologies, such as preimplantation genetic diagnosis (PGD) and fresh embryo transfer (NEET). PGD technology can diagnose whether an embryo carries a certain genetic disease, and NEET technology can directly transplant fresh fertilized eggs into the uterus, improving the success rate of transplantation.
In addition, the third generation IVF technology also introduced new culture media and conditions in the process of embryo culture, improving the quality and survival rate of embryos. By optimizing the nutrients and growth factors in the culture environment, we can help the embryo develop better and improve the pregnancy success rate.
Summary
The third generation of IVF is an advanced reproductive technology based on the first and second generation of IVF, combined with the latest technological progress. In vitro fertilization includes ovulation, oocyte retrieval, sperm retrieval, in vitro fertilization and embryo transfer. The progress of the third generation IVF technology is mainly reflected in the accurate embryo screening and selection, the application of assisted reproductive technology and the improvement of embryo culture conditions. These advances make IVF technology have a higher success rate and fewer risks, providing better hope for couples who cannot conceive naturally to achieve their reproductive aspirations.
