What is IVF?
IVF, also known as in vitro fertilization embryo transfer (IVF-ET), is an assisted reproductive technology designed to help couples who cannot conceive naturally achieve their reproductive aspirations. It is the process of culturing and combining eggs and sperm into embryos in vitro, and then transferring the embryos to the mother's uterus for growth and development.
The normal pregnancy process is that the sperm enters the egg in the female body, and then through a series of development processes, it finally embeds into the endometrium. However, some couples are unable to conceive naturally for a variety of reasons. At this time, IVF technology becomes their hope to achieve fertility.
Procedure of testicular sperm extraction
Testicular sperm extraction is a procedure for removing sperm that cannot be discharged naturally. The general procedure of testicular sperm extraction will be introduced below.
First, the doctor will conduct a general examination of the patient to determine the patient's physical condition and suitability for surgery.
Then, the doctor will give the patient local anesthesia to reduce the pain.
Next, the doctor will inject physiological saline into the testis to help accurately locate the sperm.
Later, the doctor will use a special needle to puncture the testicle to remove the sperm.
Finally, the doctor will process and save the sperm for subsequent testing and use.
Success rate of IVF technology
The success rate of IVF technology is affected by many factors, including age, patient's physique, doctor's experience, equipment and technology. Generally speaking, the success rate decreases with age.
According to statistical data, the average success rate of IVF in the world is about 30% to 40%, which means that there is about one third to one quarter of the chance of successful pregnancy in each attempt. Of course, the success rate will vary from hospital to hospital and from region to region.
However, with the continuous progress of medical technology, the success rate of IVF technology has improved in recent years, which has realized the dream of fertility for many couples.
Prospects and prospects of IVF technology
The rapid development of IVF technology is constantly improving couples' fertility difficulties. In the future, we can look forward to the following developments and prospects.
First, with the development of gene editing technology, transmission of some genetic diseases will be avoided. Through gene editing of embryos, the existence of certain disease genes can be confirmed and their transmission to offspring can be prevented.
Secondly, IVF technology may be increasingly applied to single women or same-sex couples. With the change of social concepts, for independent women and same-sex couples, IVF technology provides them with the opportunity to achieve their reproductive aspirations.
In addition, with the further research on the process of embryo development and implantation, the success rate of IVF technology will continue to increase, bringing good news to more couples.
summary
IVF technology is an assisted reproductive technology, which helps couples who cannot conceive naturally realize their reproductive aspirations by fertilizing eggs and sperm in vitro and cultivating embryos, and then transplanting embryos into the mother's uterus. Testicular sperm extraction is a commonly used technique to remove sperm that cannot be discharged by natural means. The success rate of IVF technology is affected by many factors, but with the continuous development of medical technology, its success rate is expected to increase. In the future, IVF technology will be more applied to genetic disease screening and single women or same-sex partners. The development of IVF technology will bring fertility hope to more couples.
