Taking this problem new evening paper to breath out cure big center of one courtyard reproduction seeks the solution.
The grain of rice that encountering 33 years old opportunely comes with husband resumptive they are deposited those who be here is refrigerant " embryonic " , husband and wife two tell new evening paper, they prepare to be greeted " 2 embryoes " darling. This comes to the bub on the world at the same time with his elder brother, had been in - awaited 5 years in the canister of liquid state nitrogen of 196 ℃ .
5 years ago, grain of rice and husband first time come to a hospital transplanting is embryonic. Burning hot summer, husband of grain of rice is wearing the black business suit when marrying earnestly, for the husband and wife that just conceives the child to having gone through hardships because of this day, too important.
If call sperm egg union the first pace that is born for life, so, embryonic lab is the place that life of test tube baby begins.
In last few years, the person of center of breed of a future life is increasing. Doctor An Yuan tells new evening paper, every 8-10 is infecund to there is one to be opposite in husband and wife not Yo. Be in previously outpatient service, a month can meet unexpectedly of a few little weak choice, but the man that there is an in part about now loses less essence of life, this and they stay up late, control muscularity, work and rest not the rule has immediate concern.
Go up to be not being conceived the husband and wife that the child comes round to see a doctor, the doctor should make clear the pathogeny above all. If be to have tubal block, not oviposit, uterus misshapes or the man loses less the patient of the disease such as spermatozoon disease, want the child to need to have test tube baby.
Be in reproductive center, the most mysterious place is embryonic lab, because here is a place that new student life begins. Here, embryology expert can combine parental spermatozoon and ovum, until form embryo.
From 2007 reproductive center holds water begin, ji Gongping is here " majordomo " , up to now, her administer is worn many 7000 archives.
The idea of people ran, see the patient dare not greet sb outside so, but now won't, and everybody still is met send the picture of darling actively to small letter group in; So some people think come to a center take an ovum, wait for 10 months to be able to adopt the child, but now people to test tube baby already no longer unfamiliar.
New evening paper brings young associate first people the working environment that knows embryonic lab. Unlike the crowd with bustling outpatient service, in embryonic lab quiet all the more. Embryology expert is in before entering mysterious hut, should use first cap, guaze mask, dustproof take etc " fully armed " , next repass wind drenchs disinfection. Hut imitate " mom abdomen " the environment in, not only control of dim, temperature is in the light (23 ± 2) ℃ , humidity is in 40%-60% . Every want open before the job half hours day to exceed clean workbench, hot stage, heat board, air to purify wait for equipment, check all carbon dioxide chroma that develop case and temperature, still have work station the face is mixed the temperature of heat board.
Use all sorts of high spirit device, embryology expert should undertake education radical preparation, choose the many measure such as egg, seminal processing, be fertilized, embryonic grading, embryonic transplanting, refrigerant defrost, whole process must not have one silk is careless.
When walking in the house, hold embryo child embryonic staff member is first, drawing near other personnel needs to give way, in addition, retrogression does not allow to walk inside embryonic lab, in order to prevent collision. A lot of operations need two-men to check, ensure no risk at all.
Not only such, because of embryo " be afraid of flavour " idiosyncratic, embryology expert cannot use perfume before retiring 60 years old, make up, and ask as a result of each operation asepsis, also do not allow to adorn in the job the thing of ring and so on.
Why should undertake to embryo refrigerant? Basically have two respects reason, it is mom hurried oviposit, after be united in wedlock with father's spermatozoon again, can form many embryo. After undertaking transplanting, if still remain the embryo with good quality, OK them refrigerant save. Such, if fresh transplanting does not have a success, when perhaps wanting to give birth to 2 embryoes later, OK and direct will refrigerant embryo takes transplanting, can make father mother little meet with blame. 2 it is a lot of accurate mom can appear after hurried oviposit ovarian and excessive stimulation is asked for integratedly, perhaps do not suit the situation of embryonic bed when the film inside confinement palace. To assure to follow mom and embryonic security, choice general embryo is so refrigerant save, await intrauterine this " soil " enough and fecund when reentry transplants all right.
So are these refrigerant embryo how save? Doctor An Yuan tells new evening paper, embryonic meeting is put in special and refrigerant protective agent, after the course is handled, again park - in the liquid nitrogen of 196 ℃ .
Below this kind of extremely low temperature, embryonic metabolization is dormant almost, can save for a long time. If be not taken out all the time, do not abolish, embryonic likelihood survives about a hundred years longer even.
There are 6 supports in canister of every liquid state, there are 10 tubes on every bracket, a family is in every tube is refrigerant and embryonic.
In deposit " Sleeping Beauty " in liquid nitrogen canister, the embryo that microtherm saves is put quickly into defrost fluid, embryology expert leaves elaborate operation in microscope, let embryo anabiosis step by step. Make a bit in containing a lot ofnutrition to be like the education fluid of the warmth like mom temperature again rest, embryo can be transplanted to enter mom's uterus, begin it to give birth to the new journey that hit the target.
The embryology expert here can be " appearance association " , they can choose the embryo with beautiful appearance only, open a little joke just, the opportunity that succeeds because of beautiful embryonic bed is greater, make a new life.
The arrival of husband and wife of grain of rice, let them deposited the refrigerant embryo that is here 5 years to have the opportunity that is waked up. To grain of rice, refrigerant embryo is not new, the first embryo because of her also by refrigerant over- .
Embryology expert finds the tube with refrigerant and embryonic grain of rice, took out an embryo that has 8 cells. Every other a few minutes, the liquid with immigrant and different embryo, after waiting for embryo to be extended slowly, help it again " bathe " , wash wrap up sticky on embryonic body sticky protective fluid. Next, will embryonic " armor " cut thin, undertake assisting hatch, make embryo easier embrace mom's uterus.
Grain of rice cannot help exclamation magical, this bub comes to this world at the same time with his little elder brother, but because of embryonic and refrigerant technology, their age differred 5 years old full.
Doctor An Yuan also explained the doubt of a lot of people: The meeting after aspic baby is born and average baby are euqally healthy. Current research makes clear, refrigerant embryo won't increase offspring to be born the risk of blemish, the filial generation that is born with natural conception is same.
Actually, there still is a few in canister of liquid state nitrogen " aspic darling " waiting silently to be taken to come home, in the process that await, they are discarded probably, be forgotten even.
In embryology lab, canister of nitrogen of two liquid state deposits move and parents to break couplet centrally " aspic darling " . The ethical committee of the hospital sets, break couplet the embryo of 3 months above, reproductive center has the right to abolish its. Embryology expert Zhang Yajuan tells new evening paper, they also had thought is to state other still way will abolish in the newspaper, but cannot bear again the heart is done so.
Once become pregnant successfully, a few families that plan without 2 embryoes can come a center actively, sign the agreement that agrees with abolish embryo, right now, reproductive center can hand in the agreement to the ethical committee of the hospital. Can focus a time next, the embryo that signs these deserted agreement is taken out from inside liquid state nitrogen, let them lose active. Be in several days ago, reproductive center has held a ceremony, below the testimony of ethical committee and lawyer, embryonic expert from - those embryo are taken out in nitrogen of liquid state of 196 ℃ , this also is meant, they make life without the opportunity again.
