This year, the “comprehensive two-child” policy was introduced, opening the door to families previously constrained by policy, remarried families, divorced families, and others who, because of their relative desire to have monkey treasures。
In the large workforce, there are not a few elderly families looking for children. In an interview with the minister of health, dr. Wang xiaoyu, director of reproductive medicine, beijing maternity hospital, stated: “it is clear that there is an increase in the number of people in their 40s who want to be in vitro babies, even in their 50s and 60s.”
The country's already high demand for assistive reproductive technology, combined with a “full-scale two-child” reproductive army, has led to a small number of centres of reproductive medicine being overcrowded. Moreover, the success rate of in vitro infants is still between 30 and 40 per cent, so it is not easy to have a child of their own。
In this situation, do you have any reluctance to try the test tube baby
Don't be afraid, healthy men have brought in experts today to give you all the test tube babies you should know
First, let us look at the process that is needed to allow a new life to be formed in vitro and to be conceived in a special way in the womb
Comprehensive medical examination
Ovulation treatment
Not every egg is fertilized, not every fertilized egg develops into a viable embryo, and therefore multiple eggs from the female body are needed to ensure transplantable embryos, requiring female ovulation therapy。
Take the eggs
The doctor, under superdirection b, uses a special needle to pierce a mature ovoli through the vagina to suck out the egg. The removal of eggs is usually carried out under intravenous anesthesia, so that women do not feel the pain caused by the piercing process。
In vitro fertilization
When women take eggs, men take them. After a special washing process, the sperm is placed in a special culture base for natural integration. It's called conventional fertilization. Icsi conventional in vitro fertilization may be necessary for some people with very few sperm. The conventional approach is not appropriate。
Embroidery transplant
A few days after fertilization, the best embryos are moved to the mother's womb through the cervix with a thin embryo transplant tube. Depending on age, the quality of the embryo and the outcome of the previous ivf, the number of embryos to transplant is determined, usually two to three。
Embroidery freeze
If there are remaining available embryos, they can be refrigerated and transplanted after the fresh cycle (that is, the ovulation cycle) has failed. This step is not experienced by everyone, as women with poor ovaries often do not have excess embryos。
Yellow body support
As a result of the application of gnrh agonists/resistants and anti-ovulation drugs, as well as the loss of ovulation granule cells resulting from the taking of eggs, women are generally under-functional in yellow during the ovulation cycle and need to be supplemented/supported with yellow ketone and/or fuzzy membranes。
Determination of pregnancy
The serum hcg was determined 14 days after the embryo transplant to determine if it was pregnant. The serum hcg was recalculated 21 days after the embryo transplant to understand the development of the embryo. 30 days after the embryo transplant, a vaginal ultrasound is conducted to determine whether there is an intrauterine pregnancy and whether there is a heartbeat。
Knowing the process, the good health man has invited many experts to answer your questions about the in vitro baby
Are you fit for test tube baby
Q: which population does in vitro baby technology apply to? Are older people more suitable for choice
Prof. Sovry, chief expert at the reproductive centre of the beijing gynaecology hospital, described “technology of in vitro infants” among the following groups: female ovarian tubal infarction, ovulation disorder, intrauterine anisopathy, male incompetence or incompetence insufficient for artificial insemination, immunopregnancy, and infertility for unknown reasons. The general physician advises the patient to consider in vitro baby techniques only if the patient is still unable to perform endocrine treatment, artificial insemination, etc。
In general, over 35 years of age, the need for women who clearly go downhill with ovarian functions is greater. I do not encourage media reports that a 60-year-old divorced woman has obtained a pair of twins through an in vitro baby. The birth of a child at an older age is of little benefit to the next generation, and the success rate of in vitro babies is decreasing as age increases。
Yu qi, deputy director of gynaecology and gynaecology at beijing and hospitals: the fit population of in vitro babies is not necessarily related to age, and the age factor affects the average female and in vitro babies equally, without regard to other factors. For example, an in vitro baby can also be tested if there are problems for women, such as the lack of a tube。
The expert cautioned that, for both financial and therapeutic reasons, patients were advised to proceed with treatment step by step, starting with the choice of the most natural and simple way. However, it is possible to give preference to in vitro babies in the case of older women and those with low ovaries。
Repeated egg removal affects women's health
Q: does the removal of 10 or so eggs from the female body have an impact on the woman's health during the ovulation phase
Zhang moon-lian, deputy director of the reproductive medicine centre of the general air force hospital: there are still no findings in this regard and there may be some implications. Because the removal itself is an irritation and damage to the female ovaries, the occasional removal of an egg will have no significant impact, but some women may experience a four-to-five cycle of treatment, which may have some physical impact. It is also uncertain whether the taking of eggs will lead to an earlier age of menopause for women, since the age of menopause for different women is itself very different, and it is not certain that there is a necessary link between early menopause and the use of ovulation drugs。
Wang xiaoyu, director of reproductive medicine, beijing maternity hospital, medical university of the capital: the extraction of eggs is guided by ultrasound, and the application of ovary piercing and ejection techniques using needles does not cause significant damage to ovaries, but it is important to avoid blood vessels and check for haemorrhage. An ovarian action per se generally has no effect on the function of the ovarian, which is much smaller than an ovarian perforation operation to treat ovarian syndrome. Of course, the safety of any operation of assistive procreation techniques is being tracked and continuously studied。
About $30,000 a month and a half
Q: how long does it take to be an in vitro baby for a cycle? How much would it cost
Professor sowery, chief specialist of the reproductive centre of the beijing maternity hospital: we will determine the programme based on the age of the patient, the function of the ovary, etc. But if the ovarian function is poor and old, we predict that it will receive fewer ovarian cells and remove the pre-egg decomposition link (i. E. Inhibiting its own ovarian function), essentially for two weeks or so。
As for costs, the general public hospital has a cycle of around $30,000, and the beijing paoshima maternity hospital, although it is a high-end private maternity hospital, is not very expensive because it has just been applied for an in vitro baby project, at around $40,000 per cycle. In vitro babies are more expensive than fertilisation in a cycle of $1,000 - 2000 and are often given up for several cycles if they are not more economically powerful households。
Wang xiaoyu, director of reproductive medicine and deputy director of the prenatal diagnostic centre, beijing maternity and gynaecology hospital, university of the capital medical sciences: it will normally take about two months for both men and women to undergo pre-operative examinations in the first month and for the second month to start the cycle of ovulation, egg removal and transplantation. The cost depends on age, ovarian function and semen. Young women, ovarian functions are normal, male semen is generally normal and costs are low. If the ovarian function is poor, the ovulation time is extended, the dose is increased, or the man needs a single sperm injector for severe, weak and degenerative conditions, at a higher price than the regular patient. Prices therefore vary from person to person。
The success rate is around 30 to 40 per cent
Q: since the birth of the first in vitro baby, the success rate for in vitro babies is still around 30 to 40 per cent, and what factors may affect success? Are there clinical indicators that tell us how many cycles of failure are to be judged hopeless
Zhou liyong, deputy director of reproductive medicine at beijing maternity hospital: many factors affect the success of in vitro babies. Age is a very important factor, with women over the age of 35, the loss of ovarian reserve function, changes in the quality of ovarian cells, a corresponding increase in chromosomal anomalies, and a decrease in embryo cultivation, which also leads to low success rates。
Reina, wang, north medical centre for reproductive medicine: in vitro babies, where possible, choose high-quality embryos for transplantation, but it is true that there are people who have been embedding high-quality embryos on several occasions and are still unable to have a successful pregnancy, about 50% - 75% of this is due to the inability of embryos to grow successfully. Repeated implants failed in two cases: a single transplant of three high-quality embryos and three failed cycles of high-quality embryo transplants; and multiple transplants of more than 10 embryos failed to get pregnant。
Leftover: there is actually no precise periodic limit, and we do not generally refuse to do so as long as the patient requests it. Some people with poor ovarian functions, who do a cycle that is often ineffective, such as lack of access to ovarian cells or to embryos that can be transplanted, spend additional periods saving several more ovarian cells for in vitro fertilization and then a single transplant。
Moreover, it was often people with poor ovaries who suddenly became pregnant during a certain cycle, but also had a miscarriage, which gave her a glimmer of hope and wanted to continue。
Drugs cause premature ovulation? I don't know
Q: does the use of drugs to fill ovaries negatively affect women and lead to early ageing
Leavenley: it's actually not much. The promotion of ovulation may lead to the development of small ovulations, which are locked in the absence of maturity and generally have no impact on the ovaries function. There is insufficient evidence of premature failure。
Wang xiaoyu: appropriate ovulation promotion programmes do not generally lead to early female mortality. Every month, women have a normal advantage in ovulation, while several to a dozen have collapsed. The ovulation cycle is one in which dying eggs mature together under the effect of an ovulation drug, without affecting other ovulations in the ovaries. Despite this, there is still a need to control the volume of ovulation drugs in the development of ovulation programmes to prevent excessive irritation and reduce unnecessary complications。
If you're pregnant with multiple babies, i'd recommend a reduction
Q: can you ask for multiple babies when you're in vitro? What if we have multiple children
Wang treeyu: multiple births are complications from in vitro baby technology. The control of multiple births, the reduction of double births and the strict prohibition of three births are among the technical standards that are strictly applied. Double and multiple placentas cause hyperplasia, miscarriages, premature births, stillbirths, etc., which are far more risky than single births and can even put mothers at risk for their lives. The growth space is insufficient, the fetus is also at risk of stunting and the risk of deformation increases。
Three pregnant women are usually reduced to two or one, and two pregnant women are recommended for reduction to one. Teenage technology is a mature technique, where early birth reduction does not require injection of drugs, where embryos are generally in different velvet cavities, and ultrasound choices to retain a well-developed embryo do not generally result in retained fetal malformations, which rarely result in abortion. There is no significant risk for pregnant women or the reserved foetus。
Gender assessment only excludes genetic diseases
Q: can a baby with an in vitro have sex
Zovenli: the gender assessment of in vitro babies is not done solely for the purpose of identifying gender, but for the purpose of extracting gender-related genetic diseases, which we call the third-generation in vitro infant technique (i. E. Pre-plant genetic diagnosis pgd). Because of the gender-related nature of some genetic diseases, it was necessary to screen healthy embryos through gender-based identification, which could not be carried out for the sole purpose of sex selection. The national commission on health and family planning currently requires that reproductive centres that have been running in vitro babies for more than five years can submit applications for the pgd project for approval。
After learning about the technology of the in vitro baby, we'll look for a regular hospital where human assisted procreation can take place。
The minister of health has been informed by the beijing city health plan commission that there are currently only 12 institutions in beijing, except the military hospital, that can develop human assisted procreation techniques. Depending on, for example, the level of technology, different institutions do not perform the same technology。
