For infertile families, the purpose of choosing IVF is to get a healthy and smart child through this technology, however, Hengjian Overseas recommends that before doing IVF, we must understand the entire process steps of IVF to help everyone better complete IVF treatment and arrange life and work in advance.
How long does it take to do an IVF process? IVF is medically known as IVF – embryo transfer. The whole test tube process down, generally a test tube takes about twenty-five days to thirty days.
Test tube process:
1. Physical examination before surgery
In order to determine whether both husband and wife are suitable for IVF, women need to undergo a comprehensive physical examination as soon as possible, such as checking the level of hormones in the body, checking whether the uterine environment is suitable for conceiving a new life, checking gynecological aspects, and avoiding symptoms such as acute infection of the reproductive tract affecting the success rate.
2. Downgrade
Before performing IVF, women need to do a ultrasound examination, and then choose a suitable surgical plan according to their own situation and follow the doctor's advice.
3. Ovulation induction therapy
Since 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.
4. 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.
5, 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.
6. Embryo transfer
A few days after fertilization, a very thin embryo transfer tube is applied, the best embryo is transferred into the mother's uterus through the cervix, and the number of embryos transferred is determined according to age, embryo quality and previous IVF outcomes, usually 2 to 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.
7. 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 3 weeks after ultrasound sees fetal heartbeat.
8. 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 that since the opening of the two-child policy, there are really people who are happy and some who are sad. When receiving counseling, patients who are planning to conceive a second child often ask, I am more than 40 years old, can I still do IVF? Does it mean that girls over the age of 40 should not go to IVF, in fact, is this not the case? The best age for women is 25-28 years old, more than 30 years old, women's ovarian function began to show a downward trend, 35-40 years old decline is more obvious, fertility after 40 years old is extremely significantly reduced, 40-45 years old fertility rate is left 10-20%, after 45 years old can naturally conceive only in 1% -2%, less than 5%.
Although women are too old, the ovarian response to drugs will be reduced, and the rate of fetal malformations is higher than that of young women, it can only be said that too old age affects the success rate of IVF, but it does not mean that ivy cannot be done at an older age. And in recent years, the majority of elderly patients in IVF people, however, the success rate is also increasing year by year, so patients should not be too pessimistic, but do not take it lightly. It is recommended that women who want to do test tubes should be early.
