test tube baby the same as artificial insemination ?
is of course different.
The main difference between the two is the place of insemination. Artificial insemination is in vivo fertilization, and IVF is in vitro fertilization.
Artificial insemination is a simulation of natural law, and IVF is a self-made law of artificial intervention. The analogy is the same as beauty, some people have a facelift completely changed face, some people have a partial or nose, or eye, or mouth trim. Another example is tourist scenic spots. Some places are built entirely artificially, and some are partially increased or decreased.
Can you understand the mystery? Can the experience be the same?
(1) Test-tube baby
Test-tube baby in the general public's psychology has been given modern science mystery, the last hope of holding a child. But IVF is not suitable for anyone. The birth of a method is not omnipotent, it has the most suitable audience.
IVF is the common name of in vitro fertilization-embryo transfer technology, which uses artificial methods to fertilize eggs and sperm in vitro (in vitro), and carry out early embryonic development (3 days to 6 days), and then transfer to the mother A baby born in the womb.

, the first generation of IVF technologyThe general solution is infertility caused by female factors. Get eggs and sperm, let them be fertilized in vitro and then transplanted into the uterus;
such as: severe fallopian tube disease, such as pelvic inflammatory disease lead to blockage of the fallopian tube of , water; or tuberculosis of the uterus Normal endometrium; or ectopic pregnancy postoperative fallopian tube blockage; endometriosis, immune infertility, unexplained infertility, unruptured follicle syndrome, etc.;
second-generation IVF Technology generally solves the infertility caused by male factors, namely oligospermia, asthenospermia, and teratospermia. After taking the egg and sperm, injects sperm into the egg allows it to be fertilized and then transplanted into the uterus for pregnancy .
The third-generation IVF technology solves the genetic factors of existing disease manifestations in the families of both males and females, that is, those who have genetic diseases that need to be diagnosed before transplantation, take eggs and sperm, and allow them to undergo natural in vitro fertilization. , Carry out in vitro embryo screening, weed out embryos with genetic diseases, selects healthy embryos and then transplanted into the uterus for gestation.
At present, there are more than 100 genetic diseases that can be diagnosed and detected in the third-generation IVF, such as thalassemia , hemophilia and so on. There are more than 4,000 kinds of genetic diseases in the world. If the genetic diseases can be determined before embryo transfer, the risk of miscarriage will be greatly reduced and the quality of babies after birth will be improved.
Therefore, each generation of IVF has its own special scope of application, and each has its own advantages and disadvantages. It is not that the higher the algebra, the better.

Artificial insemination refers to the collection of semen and sperm using non-sexual intercourse methods such as masturbation or special methods to take sperm.It is a assisted reproduction technology that sends sperm directly to the female reproductive tract after artificial processing and purification to achieve the purpose of conceiving a woman. Its fertilization is carried out naturally in the body, so the processing is simple, has less artificial interference, natural selection, survival of the fittest, and conforms to the laws of biology.
Artificial insemination has husband's sperm artificial insemination, artificial insemination with sperm.
Husband's semen artificial insemination indications: male genital malformations such as epispadias, hypospadias, refractory non-ejaculation, severe premature ejaculation, reverse ejaculation, or drugs, psychological, physiological factors that cause impotence, no ejaculation or Other sexual dysfunction conditions; abnormal semen quality in men, such as oligospermia, excessive semen viscosity, low sperm motility rate, poor semen liquefaction, etc.; women’s vaginal stenosis, intravaginal scar adhesion, and too loose vagina to store semen , Sperm dysfunction in the female reproductive tract or abnormal cervix and mucus, such as inflammation of the cervix and the presence of anti-sperm antibodies in the mucus; unexplained infertility.
Sperm donor semen artificial insemination Indications: Men are absolutely infertile, mainly azoospermia, teratozoospermia, teratozoospermia, etc., which are not effective after multiple treatments; men have serious genetic defects or Inherited diseases, or men who carry bad genetic genes, who are considered to be at high risk for babies born with inherited diseases after genetic counseling; special blood type incompatibility or other immune incompatibility factors between husband and wife can cause miscarriage, premature birth and newborn Infant malformation or severe fetal hemolysis; male vas deferens blockage, trauma or vas deferens ligation can not be re-canned after vasectomy, resulting in impaired sperm drainage; other unexplained infertility for which the treatment is ineffective.
