With the continuous development and progress of IVF technology, more and more infertility families have been selected, but due to the particularity of IVF, the vast majority of patients are first contact with this fertility technology, so many people do not know much about IVF, especially the specific operation process of IVF. So, what is the specific process of IVF?
Hengjian Overseas said that as long as the early stage of pregnancy preparation, through the physical examination, in line with its test tube standards can be prepared to enter the week, once officially into the IVF treatment cycle, it means to start such a series of processes and steps, including preoperative routine examination, the establishment of medical records, the signing of informed consent, ovulation induction, egg retrieval, embryo transfer, etc. The whole treatment process cycle is longer than the general surgery, about 25-30 days, due to each person's age, physical conditions are different, the treatment cycle will fluctuate to a certain extent, but the overall difference will not be very large.
In general, ivory infants follow the steps needed to determine the needs from the initial induction to the final pregnancy:
1. Ovulation induction therapy
When couples who are trying to conceive plan to do IVF, women need to first undergo ovulation induction therapy. This is because not every egg can be fertilized, not every fertilized egg can develop into a viable embryo, so multiple eggs must be obtained from the woman's body to ensure that there are embryos that can be transferred, which requires ovulation induction treatment for women.
2. Egg retrieval
Under the guidance of ultrasound B, the doctor applies a special egg retrieval needle to puncture the mature follicles through the vagina and aspirate the eggs. Egg retrieval is usually performed under intravenous anesthesia, so women do not feel the pain caused by the puncture process.
3, IVF
Sperm retrieval: When a woman retrieves an egg, a male performs a sperm retrieval. After the semen undergoes a special washing process, the sperm eggs are placed in a special medium in order to combine naturally. This is called conventional fertilization.
4. Embryo quality screening diagnosis
PGS/PGD This is the third generation of ivy technology unique, the use of technical means to screen and detect embryonic cells, screening out bad genes, chromosomal abnormalities and genetic diseases, select healthy and high-quality embryos for transfer, but also to improve the success rate of IVF and ensure the health of the baby after birth, to avoid the fetus after birth by health problems, to truly achieve eugenics.
5. Embryo transfer
A few days after fertilization, a very thin embryo transfer tube is applied to transfer the best embryos into the mother's uterus through the cervix, and the number of embryos to be transferred is determined according to age, embryo quality and previous IVF outcomes, usually 2-3 embryos. In recent years, in order to reduce the rate of multiple pregnancies, some centers have opted for single embryo transfer, or up to 2 embryos. Because the embryo transfer tube is very thin and the doctor moves gently, the patient usually does not have any pain.
6. Luteal support
Due to the use of GnRH agonists/antagonists and ovulation-stimulating drugs, as well as the loss of follicular granule cells due to egg retrieval, women often have luteal insufficiency during the egg retrieval cycle and require luteal supplementation/support with progesterone and/or chorionic gonadotropin. If you are not pregnant, stop progesterone and wait for menstruation. If pregnant, progesterone is continued, usually up to 3 weeks after ultrasound B sees fetal heartbeat.
7. Determination of pregnancy
Serum hCG is measured 14 days after embryo transfer to determine pregnancy. Serum HCG is measured again 21 days after embryo transfer to understand how the embryo is developing. 30 days after embryo transfer, a vaginal ultrasound is performed to determine whether there is an intrauterine pregnancy or not, with fetal heartbeat.
Hengjian overseas tips: IVF as a medical operation, there is currently no 100% success, so not every female friend who does IVF can be 100% pregnant, at present, the domestic success rate is generally around 40%, and foreign countries are relatively high, reaching more than 70%. Therefore, patient friends must not put too much pressure on themselves and learn to relax their mentality, because no matter how much pressure, the final result is only two - success or failure.
