Going to the United States for IVF:5Will the embryos of the sky continue to be raised？

Embryo culture is an important project in clinical embryology of in vitro fertilization。It depends on the stability of the reproductive center、High quality embryo culture system、Proficient embryo culture techniques and doctors' profound understanding of embryo quality。nowadays,With the continuous development of assisted reproductive technology、Continuous optimization of ovulation promotion programs and improvement of embryo culture systems,The success rate of in vitro fertilization has also greatly increased。

usually,The reproductive doctor will culture the fertilized egg into an early embryo on the third or fifth day,Then transplant it into the female uterine cavity,In order to facilitate smooth implantation,Improve the pregnancy rate of women。Regarding blastocyst culture,Some friends asked,Go to the United States for in vitro fertilization5Will the embryos of the sky continue to be cultured?

Go to the United States to do a test tube,5Will the embryos of the sky continue to be cultured?

United StatesHRCReproductive experts say,In vitro fertilization blastocyst culture generally takes five to six days,This is the final stage of in vitro embryo culture,Embryos are composed of100Composed of multiple cells,Complete structure,Shape stability,Strong vitality,Embryos are more in line with the physiological state of the female uterus,Implantation into the uterine cavity can quickly adapt to the uterine environment,Continue to grow and develop,therefore,Embryo transfer can greatly improve implantation rate and female pregnancy rate。

Go to the United States for in vitro fertilization,5The blastocyst of the sky will continue to be cultured, which depends on the actual situation,Because each fertilized egg is different,Some fertilized eggs do not form blastocysts by the fifth day of cultivation,Not reaching the ideal state,Then the embryo specialist will continue to cultivate it,Until the sixth or seventh day, check the morphology and structure of the embryo(Not exceeding7day),Assist in obtaining high-quality mature blastocysts,Lay a solid foundation for the next stage。

Tips:Usually on the the fourth day,Cells enter rapid division phase,Formed on the fifth or sixth day100Multiple cells,Composed of pluripotent cells,Strong stimulation of developmental potential,Has the potential to develop into a complete fetus；Regulation ability of blastocyst cells、Strong adaptability and implantation ability,More in line with the physiological state of the uterus,Implantation into the uterine cavity can synchronize with the growth of the endometrium,Can quickly implant and conceive,therefore,Now going to the United States to become a test tube expert is to cultivate fertilized eggs into blastocysts,Then perform genetic testing,Then select high-quality and healthy blastocysts for transplantation into the female uterine cavity,In order to facilitate smooth implantation and complete pregnancy。

The key to successfully cultivating test tube embryos for the United States lies in the following three points:

(1)Advanced laboratory instruments and equipment

One of the keys to successfully cultivating blastocysts is having an advanced embryo laboratory,Because it is a high-tech assisted reproductive technology。Only at temperature、Appropriate humidity、sterile、Cultivate in a dust-free laboratory,The fertilized egg can grow and develop smoothly to the blastocyst stage。for example,There are three in the United StatesHRCThe reproductive hospital has been approvedCLIA、CAPAdvanced embryo laboratory with dual level certification,Can provide a good environment for blastocyst culture and even the entire test tube operation。

According to experts,United StatesHRCThe laboratory is equipped with a microscope operator、Embryo culture incubator、Spindle observation system、Laser film breaking instrument、PHMeasuring instrument、Incubator、Complete and advanced instruments and equipment such as air purification systems,Simulation of female uterine environment in blastocyst culture incubator,Place the fertilized egg in temperature and humidity、oxygen content、Growing and developing in an environment similar to that of the female uterus, such as acidity and alkalinity,Successfully developed to the blastocyst stage。

(2)Develop high-quality culture medium

High quality culture medium is another key factor for successful blastocyst culture,Because the energy source for the growth and development of fertilized eggs is the culture medium,Therefore, its energy matter、Nutrition、Osmotic pressure andpHThe value must be consistent with the growth environment of the embryo in the maternal environment,To ensure the smooth growth and development of fertilized eggs。

United StatesHRCReproductive hospital embryology experts will develop high-quality culture media based on the nutrients secreted by the female uterus,Like amino acids、vitamin、Proteins, etc,To ensure the smooth growth and development of fertilized eggs into blastocysts。

(3)Expert qualification in embryology

Embryo culture also has high requirements for embryology experts。They are in the United StatesHRCThe reproductive hospital has qualified embryology experts。They have professional medical knowledge,Proficient in advanced blastocyst culture techniques,Having rich training experience。for example,Experts strictly control and regulate the use of incubators、Dosage and replacement of culture medium、Embryo development and time monitoring,This helps to obtain high-quality blastocysts。

United StatesHRCReproductive experts will utilize advanced third-generation in vitro fertilization technology,Genetic screening and diagnosis of all chromosomes in blastocysts,Check for chromosomal duplication in blastocysts、Abnormal situations such as loss or translocation,Does it carry genetic defects or mutations that cause certain diseases,Then choose high quality、Transplanting healthy blastocysts,Thus effectively avoiding adverse situations such as fetal arrest and miscarriage caused by chromosomal abnormalities,Preventing the transmission of genetic diseases,Ensuring the health of future generations,Realize eugenics and nurturing。
