What is baby of the 3rd acting tube? The genetics before baby of the 3rd acting tube also says embryo is embedded is diagnosed (PGD) , before showing in test tube baby embryo transplants, the genetic matter that takes embryo undertakes an analysis, diagnose discrepant constant, choose healthy and embryonic transplanting, prevent the method that hereditary disease delivers.
Detect normally material takes 4 ~ the egg of a cell of embryo of 8 cellular period or be fertilized around just a little extremely body. Sampling does not affect embryonic growth.
Technology of newest baby of the 3rd acting tube can eliminate gene flaw, cope with hereditary disease. Introduce according to domestic reproduction expert, if connubial both sides carries hereditary disease gene, if mediterranean is anaemic, so the may be an in spite of illness child of the be pregnant with in test tube. According to the technical measure before, can let the woman be pregnant first only, be pregnant 4~6 of 7~8 Zhou He month these two phase, respectively draw-out nap and amniotic fluid will detect fetal healthy, if insalubrious choose induced labor. Such meetings cause very great harm to the female, some couples endure count even second " very reluctantly give up what one favours " , still do not conceive on healthy fetal.
To solve this difficult problem, the 3rd acting technology is in the United States emerge as the times require. Is this how a kind of magical technology? American expert says, it is with Mediterranean anaemia exemple, if both sides of husband and wife is the person that ground deficient gene is carried, the odds that has 1/4 so gives birth to the child of deficient of serious illness ground, the odds that also has 1/4 at the same time gives birth to healthy child. What should do right now is to pass technical measure winkle this " healthy 1/4 " .
The woman that is pregnant normally has an embryo only inside body, but adopt technique of test tube baby, can produce many embryo. Chinese hospital is general it is the 3rd day in embryonic development, medical personnel is met from inside every embryo a cell comes to winkle undertake detecting, single out that healthy embryo, transplant again inside the female's body. Accordingly, the genetics before the 3rd acting technology also is called embryonic transplanting is diagnosed. Like the United States and Thailand in abroad this is planted the country with more advanced technology of test tube baby, the bursa embryo that should foster embryo into 5 days normally just undertakes example undertakes sifting checking extracting an embryo, such accurately sieves check hereditary disease. At present the technology of baby of the 3rd acting tube of the United States and Thailand can have sifted fish 250 kinds of hereditary diseases. Additional, to ensure the education of bursa embryo becomes power, the United States and Thailand tube baby use technology of baby of the 2nd acting tube entirely, namely technology of odd spermatozoon inject (ICSI) , single out in order to actor or actress the most healthy the strongest spermatozoon, will let follicular be fertilized better.
No matter foster bursa embryo, odd spermatozoon injects, embryonic still sieve is checked, expended many manpower material resources, the doctor that needs to have experience very much, embryonic division and detect division will undertake, so medical treatment charge is compared common the technology of generation tube that checks without embryonic sieve is a lot of higher; And, be in Thailand and United States, the embryonic sieve that should issue an essence to allow major checks a report to need to detect with professional gene company cooperation is finished, cost accrue a lot of. The price of baby of the 3rd acting tube that at present domestic hospital makes one cycle is in above of 100 thousand RMB, foreign price is higher. If get unidentified reason is infecund, senile woman, the patient of problem of chromosome of husband and wife can choose to do baby of the 3rd acting tube.
Reveal baby of the 3rd acting tube to sift the embryonic report that check:
The embryonic A that tags color, B, D, E, F, G is health, can undertake transplanting, embryonic C, H, I, J is put in all sorts of chromosome problems, should be not transplanted. A lot of people say, husband and wife is young, healthy, without familial and hereditary disease, won't put in embryonic deformation problem, this is full of prunes idea, actually no matter size of age of male and female, put in embryonic deformation rate, just odds is smaller. Sieves of afore-mentioned baby of this the 3rd acting tube check a report to belong to a young couple (female 23 years old, male 27 years old) , the healthy rate of 10 bursa embryo is 60% . This is why sometimes young and healthy couple also can produce an embryo to stop Yo to wait not Yo is infecund circumstance.
