Doing IVF can help some couples solve fertility difficulties. Before the IVF is taken, both men and women are required to undergo some tests to ensure that the IVF can proceed smoothly. Share some successful egg donation stories to eliminate some of the disadvantages of pregnancy. Now that the technology of the third generation of IVF has matured, what is the process of the third generation of IVF?
Third-generation IVF, also known as preimplantation genetic diagnosis (PGD), refers to the method of analyzing the genetic material of embryos before IVF-embryo transfer, diagnosing whether there are abnormalities, screening for healthy embryo transfers, and preventing the spread of genetic diseases. Normal pregnant women have only one embryo, but with IVF technology, it is possible to produce multiple embryos at once. On the third day of embryo development, the medical staff will select a cell from each embryo for testing, share successful egg donation cases, select healthy embryos, and transfer them into women. Therefore, the third-generation technique is also known as genetic diagnosis before embryo transfer.
The third generation of IVF technology is the selection of non-hereditary disease factors, through the screening of embryos implanted in the mother, not only to solve the fertility problem, but also to achieve eugenics, the impact on human development is far-reaching. So, what is the third generation process of IVF? Let's start with the third generation of IVF. Share successful egg donation stories
Since not every egg can be fertilized, and not every fertilized egg can develop into a viable embryo, multiple eggs need to be obtained from the woman to ensure that there are transferable embryos, which requires ovulation induction treatment for women.
There are many ovulation induction regimens, such as standard long regimens, short regimens, and antagonist regimens. The long regimen refers to the application of GnRH agonists in the luteal phase of the previous cycle, the short regimen refers to the application of GnRH agonists on the second day of the menstrual cycle, and the antagonist regimen refers to the application of gonadotropins first, and then the application of GnRH antagonists after the follicles have grown to a certain extent. The effect of a GnRH agonist or antagonist is to prevent the spontaneous release of the egg before egg retrieval.
In general, long shows have the highest success rates, but not all women who use them are suitable for long shows. Ovulation induction regimens must be tailored to each person's specific circumstances, which is called "individualized" treatment.
Before entering the IVF cycle, most of the time, women will take birth control pills in the previous cycle to suppress ovulation and thus avoid pregnancy in the natural cycle. Share successful egg donation stories. The application of GnRH agonists before menstruation can affect the fetus (which may lead to miscarriage). In addition, for people with irregular menstruation, the use of contraceptives facilitates the determination of ovulation induction time. In addition, the use of birth control pills can also prevent the formation of physiological cysts of the ovaries, which facilitates ovulation induction therapy.
On the 2nd day of the menstrual cycle, or after satisfactory GnRH agonist suppression (reproductive hormones and uterine ovarian ultrasound results meet requirements), women begin to use ovulation-stimulating drugs. Doctors judge follicle growth based on ultrasound tests and serum hormone measurements, and decide whether to adjust the dose of ovulation-stimulating drugs. When the follicle matures, hCG is injected to promote the eventual maturation of the egg. Eggs are usually taken 36-36 hours after the injection of hCG.
Sperm acquisition: When women take eggs, share successful cases of egg donation with men. After a special washing process, the sperm eggs are placed in special medium for natural binding. This is called routine fertilization. - Healthy gestational pulse
A few days after fertilization, the best embryos are transferred to the mother's uterus through the cervix with a very thin embryo transfer tube. The number of transferred embryos is determined based on age, embryo quality and previous IVF results, usually 2-3 embryos transferred. In recent years, in order to reduce the rate of multiple pregnancies, some centers have opted for a single embryo transfer or a maximum of two embryos. Since the embryo transfer tube is very thin and the doctor moves very lightly, the patient usually does not have any pain.
Due to the use of GnRH agonists/antagonists and ovulation-stimulating drugs, as well as the loss of follicular granulocytes due to egg retrieval, women often have luteal insufficiency during the egg retrieval cycle and require progesterone and/or chorionic gonadotropin for luteal supplementation/support. If you are not pregnant, stop using progesterone and wait for menstruation. If you are pregnant, continue to use progesterone, usually until 3 weeks after the ultrasound shows fetal heart rate.
Serum hCG is measured 14 days after embryo transfer to determine if pregnancy has occurred. Serum HCG is measured again 21 days after embryo transfer, and successful egg donation cases are shared to understand embryonic development. 30 days after embryo transfer, a vaginal ultrasound is performed to determine whether there is an intrauterine pregnancy and fetal heartbeat.
The most important thing about doing IVF is to treat it according to the physical condition. At the same time, the doctor should make other plans according to the specific situation of the patient, so it is necessary to follow the doctor's drug requirements for follow-up consultation. Ivy ivy ivy (IVF) 3rd generation technology is a highly specialized technology that requires the cooperation of doctors and patients. At the same time, the accuracy of the equipment and the skills of the doctor are very important, so it is also very important to choose a regular medical institution.
The third generation of IVF technology is relatively cost-effective, mature technology, and the success rate is better guaranteed, so more and more friends decide to do IVF to help infertile people conceive children themselves.
