Will there be a situation where there are many eggs but no usable embryos when doing a test tube?

In the wonderful journey of life, the birth of every new life is full of mystery and expectation. For those who choose IVF technology to realize their family dreams, every step is full of challenges and hopes. But here

During this process, there is a phenomenon that often confuses people: Although many eggs have been taken out, why is it difficult to get usable embryos in the end?

When doing IVF,will there be a situation where there are many eggs but no available embryos?

When doing IVF, it is indeed possible that there are many eggs but no available embryos. This is mainly because although IVF technology involves multiple steps, each step is full of uncertainty. The following are a few possible reasons

Due to

t1Egg quality problem: Not all the eggs taken out are mature eggs, and the current egg maturity rate is about80%. Only mature eggs can participate in the fertilization process, while immature or poor quality eggs can participate in the fertilization process

was eliminated.

t2Fertilization problem: Even if the egg matures, it needs to be successfully combined with sperm to form a fertilized egg. However, during the fertilization process, abnormal conditions such as polyspermia and failure to directly combine sperm and eggs may be encountered, resulting in failed fertilization. In addition, subject to

Sperm rate is also affected by many factors, such as sperm quality, fertilization method, etc.

t3Cleavage rate problem: Not all successfully fertilized fertilized eggs can successfully cleave to form embryos. The cleavage rate is generallyaround 95%, and uncleaved fertilized eggs naturally cannot form embryos.

t4Embryo quality problems: The quality of embryos formed through cleavage is uneven. Embryologists will evaluate the embryos based on their morphological characteristics, and only high-quality embryos can be transplanted or frozen. Current high-quality embryo rate

Only about45%.

5But not all embryos can be successfully cultured into blastocysts. Currently, blastocyst culture is approximately

In view of this,before entering the IVF cycle, IVF fertility assistant willadvise both couples to condition their bodies before entering the week to improve the quality of eggs and sperm, which can help obtain high-quality and healthy embryos, for example

For example: adjust the diet structure, achieve a reasonable diet, maintain balanced nutrition, eat more antioxidant fruits, such as strawberries, blueberries, etc., eat more high-protein, high-fiber foods, supplement vitamins and folic acid; reduce or avoid drinking coffee

Because of the drink. In addition, women can also take coenzyme Q10 to help delay ovarian aging and improve egg quality. Men can take Nanbao Capsules to reduce sperm fragmentation rate and improve sperm vitality and quality; at the same time, strengthen physical exercise, such as slow

Running, yoga, swimming, etc. Also pay attention to rest more, avoid staying up late, and maintain adequate sleep; relax your mood, appropriately relieve stress, and maintain a happy and smooth mood, thereby conditioning your body and laying a good foundation for test-tube pregnancy assistance.

Standardize medication to promote ovulation andobtainhigh-quality eggs

Eggs and sperm are the source of life, soIVF fertility technicianswill first help obtain high-quality mature eggs and sperm. For example,IVF fertility technicianswill tailor appropriate medication plans based on women's physical conditions and ovarian function

Standardize and accurately administer drugs to ensure that the basic follicles in the ovary can develop smoothly to maturity. During the medication period, the IVFwill follow up in real time,understand the development of follicles in detail through B-ultrasound examination, and test blood to check the body's hormone levels

After that, the dosage will be adjusted according to the situation to achieve the ideal effect of promoting ovulation, help obtain high-quality mature eggs, and lay a good foundation for test tubes.

Because each woman's physical condition is different, the plan to promote ovulation for IVF is different. SpecificIVF fertility assistantswill reasonably use medication to promote ovulation based on the customer's actual physical conditions, and then use general anesthesia +B guidance when the follicles mature

method to retrieve eggs to help obtain high-quality mature eggs.

On the basis of obtaining high-quality mature eggs and sperm, theIVFwill first use single sperm injection technology to inject sperm into the egg to fertilize it, and place the fertilized egg in the culture medium. Cultivate it until thefifth or sixth day to form a blastocyst

Afterwards, the third generation of IVF PGT-M technology will be usedto conduct genetic screening and diagnosis of blastocysts to check for abnormalities in the embryo's chromosomes, and then select healthy ones. The blastocysts are implanted into the female uterine cavity

At the same time, we will protect the health of future generations and achieve excellent pregnancy and eugenics.
