What is IVF
In Vitro Fertilization (IVF), also known as assisted reproductive technology, is a process that enables infertile couples to achieve fertility through in vitro artificial fertilization with the help of physical and medical technology. This technology can help couples who are unable to conceive naturally for various reasons to successfully conceive and have healthy babies.
The process of IVF mainly includes egg collection, sperm acquisition, in vitro fertilization, embryo culture and transplantation. First, the woman received ovulation promoting drugs to increase the number of eggs. Then, after the ovarian puncture operation, the doctor collects the eggs and uses the microscope to load them into the culture dish. Next, the man provides a semen sample, which is processed and processed, and then the sperm is extracted. Doctors place eggs and sperm together in vitro to promote fertilization. When an egg is fertilized and an embryo is formed, the doctor will select the healthiest embryo for culture, usually for 2-5 days. Finally, the doctor transferred the embryo into the woman's uterus through a non-invasive method, hoping to successfully implant and develop into an embryo.
IVF is a complex medical technology, which needs professional doctors and equipment to implement. At present, there are many specialized medical institutions and hospitals around the world that provide IVF services, such as Peking Union Medical College Hospital in China, Mayo Clinic in the United States, etc.
Indications for IVF
IVF technology is widely used in the following situations:
1. The fallopian tube is blocked due to inflammation of the fallopian tube or pelvis, resulting in the inability of sperm and eggs to combine naturally.
2. Follicle dysplasia caused by polycystic ovary syndrome (PCOS) and other causes ovulation disorders.
3. The quantity or quality of the male's sperm is abnormal, and natural fertilization is impossible.
4. The woman is older, and the number and quality of eggs decline.
5. Infertility caused by other factors, such as endometriosis, immune infertility, etc.
In these circumstances, IVF technology can provide an effective reproductive choice for infertile couples.
Success rate and risk of IVF
The success rate and risk of IVF technology vary depending on individual differences and medical conditions. However, on the whole, the success rate of IVF has increased year by year, and it has become a very mature assisted reproductive technology.
The success rate is affected by many factors, such as age, quality of eggs and sperm, uterine environment, etc. According to statistics, about 30% to 40% of IVF cycles can achieve successful pregnancy. However, success does not mean absolute live birth rate, because spontaneous abortion may still occur after embryo transfer.
In addition, IVF technology also has some risks. These include the risk of multiple pregnancy, the occurrence of ovarian hyperstimulation syndrome, and fertilization failure caused by abnormal sperm or egg quality during in vitro fertilization. Therefore, before IVF, the couple should fully communicate with the doctor to understand the relevant risks and precautions.
The significance of IVF to infertile couples
IVF technology is the hope for many infertile couples to realize their dreams of fertility, which is of great significance.
First, IVF technology provides a choice for couples who cannot conceive naturally due to physiological problems. It changed their lives and gave them the opportunity to become parents.
In addition, for couples carrying certain genetic diseases or chromosome abnormalities, IVF technology can also carry out genetic diagnosis, screen and prevent the genetic transmission of certain diseases.
In general, IVF technology provides a feasible solution for infertile couples, which has important social and psychological significance.
Summary
IVF is a process to help infertile couples achieve fertility through IVF with the help of physical and medical technology. This technique is applicable to a variety of infertility symptoms, and has a certain success rate and risk. For infertile couples, IVF technology is the hope to realize their reproductive dreams and has important social and psychological significance.
