IVF.
Introduction: It is a common name for in vitro fertilization embryo transfer technology, which refers to the use of artificial methods to fertilize egg cells and sperm in vitro, and carry out early embryo development, and then transfer to the mother's womb to develop and birth of a baby. It is not a baby that is actually grown up in a test tube, but a few eggs are taken from the ovaries, and they are combined with the man's sperm in the laboratory to form an embryo, and then the embryo is transferred to the uterus, so that it implants in the mother's uterus and becomes pregnant.
Process: The first month: The first is to have a physical examination of both husband and wife to see if it is suitable for IVF.
The second month: start the drug to induce ovulation, and after the stimulation, in order to prevent the egg from being released, the drug will be used to inhibit ovulation. After the follicles are matured, the follicles are then sucked out of the ovaries with a special needle, which is egg retrieval (done by **), and this process can be carried out under general anesthesia without pain. The retrieved eggs are packed into a special culture vessel and sent to the laboratory to be matched with the prepared sperm, and if the endometrial thickness and hormone levels in the current month meet the criteria for transplantation, then the next month can be directly transferred.
If the second month is not suitable for transplantation, then wait until the endometrium and hormones have reached the optimal state for transplantation in the third month, and then proceed with the transplant.
Finally supported with corpus luteum**.
Indications:1Bilateral tubal blockage that cannot be unblocked, tubal effusion, or bilateral salpingectomy.
2.Difficulty in ovulation, such as polycystic and premature ovarian failure.
3.Endometriosis or adenomyosis.
4.The man has severe oligospermia, dead sperm, and azoospermia.
5.If you have a genetic history (chromosomal problems), you need to do a third-generation test tube.
6.Self-requested, such as asking for a gender.
The difference between one, two and three generations (one female, two males, and three genetics).
Generation: This technology is suitable for female infertility caused by fallopian tube blockage, endocrine disorders, immune infertility, poor ovarian function and other diseases, by removing women's eggs and male sperm in vitro for free combination of fertilization to form embryos, and then transplanted back to the uterus for conception.
Second generation: suitable for some infertility caused by male oligospermia, asthenospermia, azoospermia, and malformed sperm, mainly to remove the mature eggs of women, and then screen out all the sperm with good vitality and normal morphology and inject them into the follicular plasma for fertilization.
Three generations: on the basis of the first and second generation of technology, there is an additional genetic testing technology, suitable for patients with family genetic history, chromosomal abnormalities, multiple abnormal miscarriages and unable to conceive healthily, advanced age and want a healthy baby, by doing test-tube sex selection to avoid heredity, but also to screen out x (girls) and y (boys) sex selection couples. After the embryo is cultured with blastocysts, peripheral cells can be extracted for detection and identification, and embryos with a family history of genetic disease or chromosomal abnormalities can be diagnosed before embryo transfer, leaving healthy embryos for transfer.
