1. In vitro fertilization (IVF)
In Vitro Fertilization (IVF) is one of the key technologies for the success of test tube babies with amenorrhea. IVF fertilizes the female egg and the male sperm in vitro, then cultivates the fertilized egg to the blastocyst stage, and then implants the blastocyst into the female uterus. The key steps of IVF technology include ovarian stimulation, egg collection, in vitro fertilization of sperm and eggs, and blastocyst transfer.
In the stage of ovarian stimulation, doctors will use drugs to promote women's ovaries to develop more follicles to increase the number of eggs. Then, the eggs are collected through vaginal puncture. Next, the collected eggs and sperm are placed in an in vitro liquid culture dish to promote fertilization. After a certain period of cultivation, the doctor will select high-quality blastocysts to implant into the uterus of women, hoping to successfully implant and develop into babies.
The success of IVF depends on advanced laboratory equipment and professional operation technology. Hospitals usually need to have high-quality laboratory environment, equipped with high-end microscope, incubator, culture medium and other equipment and consumables. At the same time, professional medical personnel need to have rich IVF operation experience and strict operation specifications.
2. Embryonic chromosome screening technology for IVF
In vitro embryo chromosome screening technology is to screen embryos with chromosome abnormalities and reduce the birth rate of chromosomal abnormalities. Embryo chromosome screening technology mainly includes two methods: the first is the conventional method - blastocyst ecological chromosome screening technology (PGT-A), which can screen normal embryos by analyzing the number and structure of all chromosomes sampled from blastocysts; The second is the single gene disease test tube baby (PGT-M) used for assisted reproduction to screen specific genetic diseases.
The key step of embryo chromosome screening technology is to take embryo samples for genetic testing. Generally, doctors will use special liquid tools to carefully sample when the blastocyst develops to the blastocyst stage. Then, the embryo samples are sent to the laboratory for chromosome analysis. By detecting the number and structure of chromosomes in blastocysts, normal embryos can be screened and the success rate of IVF can be improved.
The success of embryo chromosome screening technology is inseparable from high-resolution chromosome analysis technology and professional geneticist team. High resolution chromosome analysis technology can more accurately detect the chromosome number and structure of embryos, and improve the accuracy of screening. A professional geneticist team needs to have rich laboratory experience and skilled analytical techniques to accurately determine whether there are chromosomal abnormalities in embryos.
3. Embryo culture technology before embryo implantation
The embryo culture technology before embryo implantation also plays a vital role in the success of the test tube baby with amenorrhea. Embryo culture technology mainly includes the selection of embryo culture medium and the time control of embryo culture.
The selection of embryo culture medium needs to be determined according to the different development stages of blastocysts. Hospitals usually choose appropriate culture media according to the quality and development of blastocysts to provide nutrition and environment for embryo development.
The time control of embryo culture is also very important. The time of embryo culture should be determined according to the quality and development of blastocysts. The hospital usually formulates a time plan for embryo culture according to the quality and quantity of blastocysts and the specific conditions of patients to increase the success rate of IVF implantation.
4. Nutritional adjuvant treatment technology
Nutritional adjuvant therapy plays an important role in test tube infants with amenorrhea. Nutritional adjuvant therapy mainly includes adjusting diet structure and nutritional supplement.
Adjusting the diet structure can provide various nutrients and trace elements needed by the body, and increase the body's immunity and pressure resistance. Doctors usually advise patients to mix their meals reasonably and increase their intake of protein, minerals, vitamins and other nutrients.
Nutrition supplement can provide vitamins and minerals needed by the body through oral, injection and other ways. Doctors usually recommend appropriate nutritional supplements according to the specific conditions of patients.
summary
Behind the success of amenorrhea IVF lies many key technologies, such as in vitro fertilization technology, embryo chromosome screening technology, embryo culture technology before embryo implantation, and nutrition assisted therapy technology. Together, these technologies have promoted the success rate of IVF and provided hope for infertile patients to realize their reproductive dreams. With the continuous progress of medical technology, it is believed that the technology of test tube baby with amenorrhea will be more mature and perfect in the future.
