Success case 1: the first IVF pregnancy sac
On July 25, 1978, Robert Edwards and Patrick Steptoe, reproductive physicians at the University of Nottingham, UK, successfully created the first IVF pregnancy sac in history. The doctors used in vitro fertilization (IVF) technology to combine eggs and sperm in a culture dish and implant the fertilized eggs back into the patient's uterus. Her mother, Lesley Brown, gave birth to a healthy baby girl named Louise Brown on July 25, 1979.
This successful case marks a breakthrough in IVF technology and provides new fertility options for infertile couples. The breakthrough research work of Edwards and Stepton laid the foundation for the subsequent IVF technology and opened the door for the birth of thousands of IVF babies worldwide today.
The success of this case has led to the development of IVF technology, which has helped many couples who are unable to conceive naturally realize their dreams. Especially for those couples who have tubal problems or male sperm abnormalities, IVF technology is the only way to realize their reproductive dreams.
Success case 2: Willow lobectomy increases the success rate
With the development of IVF technology, more and more assistive technologies have been introduced to improve the success rate. One of them is willow lobectomy, which is to remove the willow like processes of endometrium through surgery, providing a better environment for embryo implantation.
In 2011, Shandong Provincial Hospital in Jinan, Shandong Province, China, conducted a study to compare the pregnancy status of the group without willow lobectomy and the group with willow lobectomy by observing 200 IVF patients. The results showed that the pregnancy rate of the willow lobectomy group was significantly higher than that of the non operation group, and the pregnancy rate of the elderly pregnant women increased significantly.
Therefore, willow lobectomy has become an effective auxiliary technology to improve the success rate of IVF, which brings greater hope to those patients with endometrial abnormalities or trauma before willow lobectomy.
Successful case 3: PGD screening for genetic diseases
IVF technology can also be combined with embryonic gene diagnosis (PGD) to screen and select genetic diseases. PGD technology carries out gene detection on embryos before in vitro fertilization to determine whether there are genetic diseases, and then select healthy embryos for transplantation.
The Assisted Reproductive Medicine Center in Chicago successfully applied PGD technology in 2013 to help couples suffering from muscular dystrophy to have healthy IVF babies. The use of PGD technology eliminates the possibility of embryos carrying genetic diseases and reduces the risk of passing diseases on to the next generation.
The development of PGD technology makes the IVF technology more feasible and humanized, providing a safe and reliable way of reproduction for couples with genetic diseases.
Success Case 4: Egg Quality Improvement
Egg quality is one of the key factors affecting the success rate of IVF. In recent years, with the continuous development of assisted reproductive medicine, many technologies have been explored and applied to improve the quality of eggs.
The research team of the University of Liverpool in the UK found that the use of cumulin can increase the quality of oocytes and fertilization ability, thus improving the success rate of IVF. The use of oocyte maturation hormone improved the quality of oocytes of patients at the initial stage of IVF, and promoted their successful development into healthy embryos.
In addition, at the Victoria Reproductive Medical Center in Melbourne, Australia, researchers developed a culture medium called ENCELLIGROW, which can imitate the natural growth process of human oocytes, improve the problems related to in vitro culture, and help oocytes develop better.
The application of these technologies has improved the quality of eggs, increased the success rate of IVF, and provided more opportunities for infertile couples to realize their dreams.
Summary
Through the above four cases, we can see that there are many successful cases of IVF pregnancy sac. From the first test tube baby in the UK to the development of auxiliary technologies such as willow lobectomy, PGD screening and egg quality improvement, the test tube baby technology has gradually become mature and perfect.
The successful case of IVF technology has brought infinite hope to infertile couples and enabled them to realize their dream of becoming parents. With the further development and improvement of technology, it is believed that IVF technology will bring good news to more couples and help them usher in a healthy and happy family.
