What is the operation process of IVF?
IVF is a kind of assisted reproductive technology, which can realize the process of pregnancy and delivery by fertilizing sperm and eggs in vitro and cultivating them into embryos, and then implanting the embryos into the mother's uterus. The operation process of IVF will be introduced in detail in terms of indication selection, egg retrieval, in vitro fertilization and embryo implantation.
1、 Select indications
IVF is suitable for couples who need assisted reproduction, including infertile or infertile couples, women with premature ovarian failure, women with blocked or abnormal fallopian tubes, and men with abnormal sperm quantity or quality.
After consulting with a regular hospital, couples need to carry out a series of physical examinations, including basic reproductive function, sex hormone level and sperm quality, to determine whether it is suitable for IVF.
The doctor will arrange the next procedure after confirming that it is suitable for couples of IVF according to the results of various examinations.
2、 Egg retrieval
Fetching eggs is an important part of the IVF process. Usually, egg retrieval needs to be carried out during the female's ovulation period. First, doctors will use ovulation promoting drugs to promote ovarian development, so that the ovary can develop multiple follicles at the same time.
Then, through techniques such as fallopian tube intubation, ultrasound guidance or laparoscopy, the doctor punctures the ovary with a slender needle to extract the eggs from the follicle. Usually, multiple eggs can be obtained at one time to improve the success rate of IVF.
The egg retrieval operation is generally carried out through local anesthesia or general anesthesia, and the operation time is usually 15-30 minutes.
3、 In vitro fertilization
In vitro fertilization (IVF) refers to the combination of the extracted eggs and sperm provided by men in the laboratory for in vitro fertilization. First, the doctor places the egg and sperm in the culture medium respectively.
Then, select the best quality sperm to inject into the egg, or directly place the egg and sperm together to let them self fertilize. Usually, the fertilized eggs will be cultured in the incubator for 2-6 days to form embryos.
In the process of culture, doctors will monitor the development of embryos and choose the best time for embryo implantation.
4、 Embryo implantation
Embryo implantation is the last step in the IVF process. The doctor selects the embryo most likely to be implanted and developed according to the embryo development and the mother's intrauterine environment.
Implantation is usually performed by hysteroscopy or painless acupuncture. The doctor will send the selected embryo into the mother's uterus through an appropriate way to achieve the purpose of implantation and pregnancy.
After implantation, luteal support treatment is usually required to increase the success rate of pregnancy.
Summary
The operation process of IVF includes four main aspects: selection of indications, egg retrieval, in vitro fertilization and embryo implantation. After the physical examination of the couple and determination of the applicable disease, the doctor will take out the eggs during the female's ovulation period. Then, eggs and sperm are fertilized in vitro in the laboratory to form embryos. Finally, the doctor selects the best embryo for embryo implantation according to the embryo development and the mother's intrauterine environment.
The development of IVF technology provides a way of hope for infertile couples. However, IVF is not applicable to all infertility symptoms. It needs to be operated and treated under the guidance of professional doctors to improve the success rate and safety.
