What is IVF, and is it really living in a test tube? How does it come to be? How does it absorb nutrients? This is such a fascinating procedure! Let's take a closer look at what IVF is. It's not a child growing inside a test tube; they still exist within the mother's womb. Currently, most people only have an initial understanding of this new technology, but their deeper insights into its underlying principles are not as comprehensive or profound.
In vitro fertilization (IVF) is a new assisted reproductive technology, which is not yet mature in China. Therefore, experts suggest that couples who have undergone scientific treatment and still cannot conceive should consider the last option: IVF.
This means that it is not a relatively safe and reliable method of fertility treatment. Of course, if you consider undergoing an in vitro fertilization (IVF) procedure, you should also consider the possibility of its failure and prepare accordingly.
In vitro fertilization (IVF) is a new assisted reproductive technology. It is not yet mature in China, so experts suggest that couples who have exhausted all other options and are unable to conceive through conventional treatments should consider the last resort of IVF only if absolutely necessary.
So, what are the requirements for in vitro fertilization? Let's take a look together.
1. Submit a marriage certificate, ID card, and a proof of family planning services.
2. Inquire about the woman's medical history, surgical history, and infertility history through a clinical examination and treatment process. Accept a general physical examination and a gynecological and pelvic examination.
Additionally, for patients with infertility due to uterine factor issues, it is necessary to submit records of uterine examinations.
3. On days 2-3 after the menstrual cycle, test the basal hormone levels of women, and conduct a pelvic ultrasound examination and vaginal discharge examination.
4. When necessary, uterine biopsy and cervical cytology examination should also be performed.
5. Inquire about the patient's medical history and conduct a physical examination, including routine semen analysis.
6. The couple undergoes tests for hepatitis B, C, HIV antibodies, syphilis serology, liver function, blood type.
The female party is also required to undergo routine blood tests, including erythrocyte sedimentation rate (ESR), complete blood count (CBC), urine routine, coagulation function tests, electrocardiogram (ECG), and chromosomal analysis.
Who are suitable for IVF? 1. Women under the age of 30 (the younger, the better).
2. Post-infection (with a history of pregnancy) especially in cases of ectopic pregnancy, indicates that the embryo is viable.
3. The embryo culture in vitro is ideal, with multiple high-quality embryos available for transplantation.
4. For those with normal uterine conditions and successful embryo transfer, it is easier to insert the transfer catheter into the uterine cavity.
IVF Process: 1. Infertility Treatment, since not every egg can be fertilized and not every fertilized egg can develop into a viable embryo, it is necessary to obtain multiple eggs from the female body in order to ensure the presence of an embryo that can be transferred. This necessitates ovulation induction therapy for the female.
There are many different ovulation induction protocols, such as standard long protocol, short protocol, and anti-fertility agent protocol.
The long protocol involves the initiation of GnRH agonist therapy during the proliferative phase of the previous cycle, while the short protocol starts with GnRH agonist therapy starting on the second day of the menstrual cycle. The anti-progestin protocol involves initiating GnRH antagonist therapy after the follicles have grown to a certain size and following the administration of gonadotropin.
The purpose of using GnRH agonists or antagonists is to prevent the spontaneous ovulation before egg retrieval.
Generally speaking, the long-term method has the highest success rate, but it is not suitable for all women.
The ovulation induction regimen should be tailored to each individual's specific circumstances, which is what we call "individualized" treatment.
In the pre-IVF cycle, most women are given a contraceptive pill to suppress ovulation. This is done to avoid pregnancy from natural cycles and to minimize the risk of miscarriage during the menstrual phase when GnRH agonists are used (which could cause miscarriage).
Additionally, for individuals with irregular menstrual cycles, using contraceptives facilitates the determination of ovulation times.
Additionally, the use of contraceptives can also prevent the formation of physiological ovarian cysts and is beneficial for ovulation induction therapy.
In the 2nd day of the menstrual cycle, or after suppressing with GnRH agonist (the results of reproductive hormones and uterine ultrasound examination are required), women begin to use ovulation-inducing drugs.
Based on ultrasound monitoring and serum hormone testing results, the doctor determines the condition of follicular growth and decides whether to adjust the dosage of ovulation-inducing drugs.
When the follicle matures, hCG injection is administered to promote final maturation of the oocyte.
Usually, ovulation is induced by injection of hCG at 36-38 hours after the administration.
2. The oocyte retrieval procedure is performed under ultrasound guidance using a special oocyte retrieval needle, which is inserted through the vagina to aspirate mature follicles and retrieve eggs.
Oocyte retrieval is usually performed under sedation, so women do not feel the pain of the procedure.
3. In vitro fertilization sperm collection: When the female undergoes oocyte retrieval, the male performs sperm collection.
After special washing, semen was placed in special culture medium for natural fertilization.
This is the so-called normal fertilization.
4. After fertilization, a very fine embryo transfer catheter is used to insert the best embryos into the mother's uterus through the cervix. The number of embryos transferred is determined based on age, embryo quality, and previous outcomes from IVF, typically involving the transfer of 2-3 embryos.
In recent years, to reduce the rate of multiple pregnancies, some centers have opted for single embryo transfers or up to two embryos in a transfer.
Due to the thinness of the embryo transfer tube and the gentle movements of the doctor, patients usually do not experience any pain.
5. luteal support: due to the use of GnRH agonists/antagonists and ovulation induction drugs, as well as the loss of follicular granulosa cells during oocyte retrieval, women often exhibit luteal insufficiency during their oocyte retrieval cycles. Luteal supplementation or support is required, which involves the administration of progesterone and/or hCG.
If there is no pregnancy, discontinue the administration of progesterone and await menstruation.
If pregnancy is confirmed, continue the use of progesterone until three weeks after a fetal heartbeat is seen by ultrasound.
6. The determination of pregnancy is based on the serum hCG measurement taken 14 days after embryo transfer, to determine whether pregnancy has occurred.
At 21 days after embryo transfer, the serum hCG level was remeasured to assess the development of the embryo.
At 30 days after embryo transplantation, the intrauterine pregnancy was confirmed by transvaginal ultrasound examination and the presence of fetal heartbeat was determined.
The price of in vitro fertilization (IVF) is generally divided into two main parts: the cost of ovulation induction drugs, which can be expensive due to the use of imported medications, ranging from a few thousand to tens of thousands.
Additionally, the older an individual is, the larger the dosage of medication and the higher the cost.
The other part is the surgical and laboratory fees, which vary depending on different treatment methods.
Generally around 10,000 yuan.
According to surveys, the cost of in vitro fertilization treatment is generally between tens and hundreds of thousands of yuan.
The cost of in vitro fertilization (IVF) is related to the following factors: 1. The age, ovarian function, and whether there has been any abdominal surgery history determine the dosage of medication used.
2. You choose the method of in vitro fertilization, either the first generation (IVF-ET) or the second generation (ICSI), etc. ICSI technology requires higher technical standards and costs, so it is more expensive.
3. Depending on what medication you choose (imported + imported, imported + domestic, domestic + domestic, or micro stimulation).
4. If more eggs are harvested, they need to be cryopreserved and subsequently thawed during the transplantation process, which will increase the costs.
Therefore, the cost of in vitro fertilization treatment varies from person to person, depending on various factors such as the selection of services and different types of medications.
However, this is often just the cost of trying IVF once.
In fact, the success rate of in vitro fertilization is extremely low, often requiring multiple or even dozens of attempts to succeed, and the cost remains high
What should I do about infertility? There are ways to achieve a harmonious family relationship. Online consultation experts remind us that in vitro fertilization is not only expensive, but also has a low success rate of only about 30%. Normal people should not undergo in vitro fertilization, and try to choose natural conception. Although in vitro fertilization brings good news to infertile patients, it is only an assisted reproductive method and is only adopted when necessary
In vitro fertilization (IVF) has drawbacks such as high costs, low success rates, significant risks, and a higher rate of chromosomal abnormalities. Therefore, couples who wish to conceive naturally should not consider IVF.
All things have their own laws, and it's only by following nature's rhythm that we can be trusted. The best way to conceive is naturally.
During the process of in vitro fertilization (IVF) transfer, there are several key points to pay attention to: Currently, most people have only a preliminary understanding of this new technology. However, gaining a deeper and more comprehensive understanding of it is not as thorough as one might hope.
Individuals undergoing in vitro fertilization (IVF) transfer have even more reason to take care of their health. In addition to the general precautions, such as resting in bed for 48 hours after arriving home, and choosing to lie flat, sideways, or prone, except for using the toilet, it is important not to get up. This positioning is not conducive to the success of IVF. It is acceptable to lean against the bed, but the angle must be less than 45 degrees.
In addition, please be sure to avoid bathing for 48 hours.
After transplantation, it is advisable to avoid strenuous physical activities such as jogging or cycling. However, walking slowly is beneficial for health and safety. Try to keep your body in a state of rest without overexertion.
Make sure to get plenty of rest and sleep.
Beyond physical health, it's crucial to maintain a sense of peace and tranquility.
If there is abnormal abdominal pain, abdominal distension, or vaginal bleeding, it is imperative to immediately contact a medical institution for prompt management of the condition.
Beyond that, it is imperative to seek medical advice and strictly follow the doctor's instructions.
