test-tube baby technology exists to help the families of a lot of infertility, test-tube baby is an in vitro fertilization and embryo transfer technology, ivf procedure is complicated, however, also have to be careful operation, but said to thousands of times, ten thousand times more difficult than natural pregnancy is the process of the test tube babies now, general surgery is: drug stimulate ovulation - take eggs, fertilization, embryo transfer confirmation conception, can say to undergo the process of woman, go to hell for a while.
1, from a woman's body of multiple eggs
in general woman can only output one egg a month, and not every egg fertilization, so in order to get more eggs, mom needs promoting ovulation drugs in advance, but the ovulation drugs side effects is very big, can appear pregnant mother, nausea, vomiting, abdominal discomfort, weight gain, oliguria renal failure, such as ovarian hyperstimulation syndrome.
puncture take eggs
2. Under the guidance of ultrasound, with take eggs through vaginal puncture needle, extract the mature follicle, although take the eggs are generally carried out under intravenous anesthesia, but women still can feel the pain of puncture needle is.
3, side effects caused by puncture take eggs,

artificial take fine
4. Accept the in vitro fertilization (ivf)
women take eggs, men also need to take fine, semen in specially after washing with eggs to produce container, make the combination of the two kinds of material nature embryos.
to cultivate a fertilized egg
5, for embryo transfer
1 ~ 3 days later, sperm egg to form multiple embryos, the doctor will have 1 ~ 3, picked up with a very fine embryo transfer pipe, through the vagina and cervix will be implanted in the womb - not every fertilized egg develops into a dynamic embryos, so doctors often according to age, embryo quality, determine the number of embryos, such as embryonic implantation successfully, if necessary, the doctor will be reduction surgery.
due to multiple embryos to the uterus, lead to multiple pregnancy rate was significantly higher than that of natural pregnancy, pregnancy late-term abortion and the risk of preterm birth is significantly higher than single pregnancy, mothers with gestational diabetes, gestational hypertension, occurred during childbirth, and significantly increased the risk of postpartum hemorrhage.
6, confirm pregnancy
the embryo in the uterus, growth, two weeks after can go to check whether pregnant women.
a fertilized egg implanted
normal need meet sperm and egg in the fallopian tube pregnancy, and the combination, form a fertilized egg to the uterine cavity continue to pregnancy, and "test-tube baby" can be simply interpreted as experimental test tube instead of the function of the oviduct and referred to as the "test-tube baby";If implantation of a fertilized egg can not get in the woman's uterus, the above steps need to come again, the woman again want to face a new wave of hurt.
