In 88 institutions, an officialallowed to run in vitro fertilization - embryo transfer, intracytoplasmic sperm micro-injection technology, which is commonly known as the "test-tube baby."It is reported that this is the only province officially approved by the Ministry of Health officially launched "test-tube baby" technology institutions."Test-tube baby" was born in what?Recently, the reporter went into anReproductive Medicine Center, has witnessed the test-tube baby "born" the process.
Five-day test-tube baby "born"
Test-tube baby "born" is the first step.Remove eggs after treatment, the Add to cultivate a mature medium.Remove the eggs as a result of the maturity of different culture, like the time is not generally in the 24-48 hours between.Center for Reproductive Medicine, a medical doctor needs to closely monitor the culture medium of the egg, the egg once the sperm mature and started to admit it.After the sperm out, the need for microscopic examination, the selection of better quality, using a needle injected into fertilized eggs in the formation of, and sometimes their doctors directly on a Petri dish, the natural formation of fertilized eggs.
Fertilized egg to embryo, the need for three days.Three days, the fertilized egg, "sleep" in the warmth of the training box, while fertilized eggs divide, becoming two cells, four cells, eight cells.
When the embryo formed, the doctor will use a special tube into the uterus, in B-guided embryo transfer in the cavity.In this way, the eggs in about five days to leave the mother and then returned to the body in situ, a small life quietly in her mother's body is "born" and began breeding.
Test-tube baby "born" may seem simply a few steps, but in reality every step of the operation are demanding performance standards.Fertilized eggs for the time being "live" box of the incubator temperature must be maintained at 36 degrees to 37 degrees, simulating body temperature, so that fertilized eggs split, growth; medical personnel before entering the laboratory, in addition to the basic disinfection, but also "wind water" half minutes,dust and fiber body.
Eggs in the human body because the environment is dark, so the eggs in vitro and transplantation process requires the body in a similar environment under the light.The first time in order to prevent the failure of embryo implantation, the extra embryos will be 196 degrees below zero in liquid nitrogen tanks to preserve for the next transplant.Save ALS method must be used, surplus embryos were put into the first Michael tube, and then 4 degrees Celsius on the environment, and then transferred to 80 degrees below zero environment, and finally transferred to 196 degrees below zero frozen in liquid nitrogen tanks .
Embryo transfer into the mother from the moment, in vitro fertilization pregnancy back and natural, like a child "conceived in October," experience, then they will and natural pregnancy baby What's the difference?According to security expertsReproductive Medicine, the test-tube baby in the intellectual, physical aspects of pregnancy and natural child birth is no different.
