Why is it necessary to undergo chromosome screening when going to Jilin for pregnancy assistance?

Clinical data from Tulip International Reproductive Center shows that embryos with internal structural abnormalities can be directly eliminated through chromosome screening. This means that doctors can accurately select healthy embryos for transplantation, significantly improving the clinical pregnancy rate of a single transfer and avoiding patients wasting time and money on ineffective embryo transfers.

Screening blastocysts and eliminating abnormal embryos

Q1: Why is it necessary to perform embryo chromosome examination during in vitro fertilization?

In assisted reproductive therapy in Kyrgyzstan, chromosome testing (usually referred to as PGT, pre implantation genetic testing) has become a key step in improving pregnancy outcomes. Its core purpose is to solve the quality problem of "seeds".

In natural conception or early IVF techniques, we mainly rely on the morphology of the embryo - that is, whether it looks good or not - to judge its quality. However, embryos with high external scores and uniform cell division do not necessarily indicate that their internal genetic material is normal. If the embryo has chromosomal aneuploidy (such as an extra or missing chromosome), it can still lead to implantation failure.

Q2: How can chromosome testing reduce the risk of miscarriage?

Miscarriage is the most heartbreaking experience that many expectant parents are unwilling to face. Scientific research has shown that a large part of natural miscarriage and biochemical pregnancy in early pregnancy are caused by chromosomal abnormalities in the embryo itself. This is a biological 'natural elimination' mechanism.

If an untested embryo is blindly transplanted, although successful implantation may be possible, chromosomal errors can cause fetal development to stagnate as the embryo develops, ultimately leading to miscarriage or fetal arrest. This not only causes physical damage to women, but also brings huge psychological trauma.

At the Tulip International Reproductive Center, PGT-A technology is used to screen embryos for 23 pairs of chromosome numbers and structures, effectively identifying abnormal embryos that can cause miscarriage (such as trisomy 16). Choosing embryos with normal chromosomes for assisted reproductive transplantation can reduce the risk of miscarriage from the source and make pregnancy smoother.

Q3: Can chromosome testing block the transmission of genetic diseases?

Yes, this is precisely the important value of the third-generation IVF technology. For couples carrying specific genetic disease causing genes, chromosome and genetic testing are the "firewall" to ensure the health of their offspring.

If both or one spouse suffers from monogenic genetic diseases such as thalassemia, hemophilia, spinal muscular atrophy, or structural abnormalities such as chromosomal translocation, these problems are easily inherited by the next generation.

Through PGT-M (Single Gene Disease Detection) and PGT-SR (Chromosome Rearrangement Detection) techniques, laboratory experts at Tulip International Reproductive Center can accurately analyze whether embryos carry pathogenic genes before embryo transfer. We only choose healthy embryos that do not carry pathogenic genes for transplantation, effectively blocking the transmission of genetic diseases in the family and achieving eugenics.

Q4: At which stage is chromosome examination performed? Will it cause damage to the embryo?

Chromosome examination is usually performed during the "blastocyst stage" of embryonic development on the 5th or 6th day.

At this point, the embryo has already differentiated into "inner cell clusters" (which will develop into a fetus in the future) and "trophoblast cells" (which will develop into a placenta in the future). The Tulip International Reproductive Center uses internationally recognized biopsy techniques, extracting only 3-5 cells from the trophoblast layer for DNA analysis.

Due to the fact that the sampling site is the part that will develop into the placenta in the future, and there are a large number of blastocyst cells, this operation will not touch the main cells of fetal development. Therefore, it has no negative impact on the subsequent development potential of the embryo and the health status after birth, and is safe and reliable.

Q5: Are there any real cases of successful reproduction through chromosome testing?

Case study: Overcoming genetic barriers, a 38 year old couple realizes their dream in Kyrgyzstan

Ms. L, 38 years old, has had two natural pregnancies in China before, but both experienced miscarriage around 8 weeks of pregnancy. After a detailed examination, it was found that Ms. L's husband has a chromosomal Roche translocation. This means that their probability of naturally conceiving healthy embryos is much lower than that of the general population, and most embryos will miscarry due to chromosomal imbalances.

With last hope, Ms. L and her husband contacted Tulip International Reproductive Center and decided to go to Kyrgyzstan for third-generation IVF treatment.

Treatment process:

Promotion of ovulation and egg retrieval: The doctor developed an antagonist regimen based on Ms. L's ovarian function and successfully obtained 12 mature eggs.

Fertilization and blastocyst culture: Six blastocysts with good appearance ratings were cultured through single sperm injection (ICSI) fertilization.

PGT-SR testing: The laboratory conducted targeted chromosome structure screening on these 6 blastocysts.

The results were astonishing: the test report showed that out of 6 blastocysts, 4 had chromosomal abnormalities (aneuploidy or imbalanced translocation), while only 2 were healthy embryos with completely normal chromosomes. If blindly transplanted at the beginning, it is highly likely to repeat the tragedy of fetal arrest.

The doctor transplanted one of the healthy male embryos into the body of a caring assisted reproductive mother (due to severe damage to Ms. L's endometrium, she chose the assisted reproductive plan). On the 12th day after transplantation, the blood test was positive for HCG, and everything went smoothly during pregnancy. Finally, a healthy male baby was born at full term.

The arrival of every life should not rely solely on the gift of luck, but rather the result of scientific selection. In Kyrgyzstan, Tulip International Reproductive Center firmly believes that through rigorous chromosome screening and professional fertility assistance programs, it can help more families avoid risks and make eugenics no longer a luxury. Don't let unknown genetic risks become a stumbling block on your fertility journey. We are willing to use professional skills and warm companionship to protect you and welcome your healthy and intelligent baby back home.
