American IVF experts answer:Why some fertilized eggs cannot be cultured into blastocysts!

The fertilized egg is the root of life。When the egg and sperm combine to form a fertilized egg,It means the beginning of a new life。IVF refers to doctors first extracting female eggs and male sperm,In vitro fertilization,Cultivate into an embryo,Then transplant it back into the female uterine cavity,Ensure its smooth implantation,To achieve the goal of pregnancy。

Tips:Embryos are the final stage of in vitro culture of embryos,Usually formed after fertilization of the egg5~7day,It refers to the100Embryo fluid composed of multiple cells and embryos within the blastocyst cavity。Due to its stable morphology、Complete structure、Strong vitality、Strong activity,High implantation rate after transplantation。therefore,in the U.S.,IVF experts usually cultivate fertilized eggs into blastocysts before transplanting them back into the female uterine cavity,To increase the pregnancy rate。

that,Why can't some fertilized eggs be cultured into blastocysts during the IVF cycle?

United StatesHRCReproductive experts say,After successful fertilization of the egg,Start dividing and developing,Early embryo formation on the third day,Morula formation on the fourth day,On the fifth day, blastocysts are formed,Then implant it into the endometrium,Absorb maternal nutrients,Then continue to grow and develop。

There are three main reasons why fertilized eggs cannot form blastocysts:One is the quality of sperm and eggs。If the quality of sperm and eggs is poor、Low activity、Abnormalities or chromosomal abnormalities,The fertilized egg cannot develop smoothly into a blastocyst。second,Poor quality of culture medium。In vitro culture mainly involves placing fertilized eggs into a culture medium,Therefore, the quality of the culture medium is very important。Energy substance、Nutrients、Osmotic pressure andpHThe value must be consistent with the growth environment of the embryo in the maternal environment,To ensure the smooth development of the fertilized egg to the blastocyst stage。third,Laboratory environment and equipment,Embryo cultivation is an advanced assisted reproductive technology,High requirements for the laboratory,Advanced medical equipment and instruments are needed as support,Need to be at an appropriate temperature、Successfully cultivated in a humidity and dust-free sterile environment。

therefore,There are many factors that affect blastocyst culture,Like the quality of sperm and eggs、Quality of culture medium、Laboratory equipment、Instruments and environment, etc。Given this,Suggest choosing reliable in the United States、A reproductive hospital with strong comprehensive strength begins its cycle,Make the success rate higher、More security。

Four important tools to improve the success rate of blastocyst culture

1〡Obtain high-quality eggs and sperm

in the U.S.HRCReproductive Hospital,Experts will first use medication to promote ovulation to help obtain high-quality and mature eggs,Using new sperm washing techniques to wash and optimize semen,Remove poor quality、Low activity、Sperm with high fragmentation rate,Ensure sperm quality,Then, single sperm injection technology is used to combine sperm and egg,improve fertilization rate ,Assist in obtaining multiple mature fertilized eggs。

2〡Highly qualified embryology experts

The success of blastocyst culture cannot be achieved without the operation of embryology experts,The use of incubators for cultivation、Dosage and replacement of culture medium、Embryo development and time monitoring, etc。,This requires strict control and standardized operation by experts。If any problems arise during this period,Embryos may stop developing or die。

in the U.S.HRCThe reproductive hospital has qualified embryology experts。They have professional medical knowledge,Proficient in advanced training techniques,Has rich training experience。Through standardized operations and strict control,Experts can improve the success rate of cultivation,Assist in obtaining high-quality blastocysts。

3〡Specially developed high-quality culture medium

Culture medium is the main source of nutrients for the growth and development of in vitro fertilization embryos,Its quality is the key to successful cultivation。in the U.S.HRCReproductive Hospital,Experts will develop high-quality culture media based on the nutrients secreted by the female uterus,Like amino acids、Vitamins and proteins,To ensure the smooth growth and development of the fertilized egg into a blastocyst。

4〡Having advanced laboratories and equipment

United StatesHRCReproductive Hospital throughCLIAThere are three、CAPThe advanced embryo laboratory with dual level certification is equipped with advanced and complete instruments and equipment,Including microscope operator、Embryo culture incubator、Spindle observation system、Laser film breaking instrument、PHMeasuring instrument、Incubator、Air purification system, etc。in addition,Embryo culture incubator simulates the uterine environment of women,Keep the fertilized egg at a constant temperature、constant voltage、sterile、Growing and developing in a dust-free environment,Ensure the smooth and successful cultivation,Assist in obtaining high-quality blastocysts。
