Specific steps of the second test tube baby
The second test tube baby refers to the second child born by both husband and wife after successful pregnancy through assisted reproductive technology and in vitro fertilization embryo transfer (IVF-ET). The process includes the following specific steps:
Step 1: Preparation
Before carrying out the second test tube baby, women need to go through physical examination and consultation to ensure that their physical condition is suitable for pregnancy. At the same time, the doctor will also evaluate the woman's ovarian function, endometrial thickness, uterine cavity morphology and other factors.
If women have basic diseases or old age and other factors that are not conducive to pregnancy, they may need to take some treatment or adjust their physical status to improve the probability of pregnancy.
Step 2: ovulation induction process
Ovulation promotion process refers to the use of hormone drugs to promote ovarian development, so that the ovary can produce multiple mature follicles. Doctors will regularly carry out ultrasound and blood tests to monitor the effect of treatment according to the development of women's follicles.
Generally speaking, the woman needs to inject follicle stimulating hormone. At the same time, the doctor will adjust the drug dose according to the situation until the follicle is mature.
Step 3: Egg collection and sperm extraction
When the follicle develops to the mature stage, the doctor will arrange an ovarian puncture to take out the mature egg. This process is usually carried out in the operating room, and the follicles are punctured to extract eggs under the guidance of ultrasound.
At the same time, when eggs are collected, sperm is taken from the man, and high-quality semen is obtained through sperm treatment and washing.
Step 4: In vitro fertilization and embryo transfer
The removed eggs are fertilized with sperm in vitro, usually in the laboratory. The doctor will put the sperm into the culture dish and combine it with the egg for a period of time until the fertilization rate reaches the ideal state.
Then, doctors will select the best quality fertilized eggs for embryo transfer. Put the embryo into the uterine cavity through the vaginal catheter, and let it naturally embed into the endometrium, waiting for the arrival of implantation and pregnancy.
What is the effect of the second born test tube baby on the body?
1. Changes in body hormones
In the process of the second test tube baby, women need to inject a lot of hormone drugs to promote ovarian development. These hormones can cause changes in female body hormone levels, which may lead to emotional fluctuations, breast pain, headache and other uncomfortable symptoms.
In addition, in the process of ovarian puncture and embryo transfer, some temporary slight pain or discomfort may occur, but usually these discomfort will disappear in a short time.
2. Psychological pressure
The process of carrying out second child IVF may bring some psychological pressure, especially for couples who have already experienced IVF. They may be full of expectation and anxiety about the outcome of pregnancy and fear of failure again. Therefore, it is suggested that both husband and wife should have psychological consultation before starting treatment and seek relevant support.
3. Risk of multiple pregnancy
Compared with the natural pregnancy, the pregnant women who gave birth to the second tube baby were more likely to have multiple pregnancies. This is because during in vitro fertilization, doctors will transplant multiple fertilized eggs into the uterus to improve the success rate of pregnancy.
However, multiple pregnancy will increase the health risks of pregnant women and fetuses, such as premature delivery, low birth weight and pregnancy complications. Therefore, the number of embryos to be transferred should be carefully selected to reduce the risk of multiple pregnancy.
4. Economic and time pressure
The process of second child IVF usually requires high economic and time costs. Including medical expenses, hormone drugs, surgery expenses, examination expenses, etc. In addition, the whole process may require multiple hospital visits and treatment, which will occupy more time for both spouses.
Summary
Two child IVF is an assisted reproductive technology, which is realized through a series of specific steps. This process will have a certain impact on women's body, such as hormonal changes, psychological pressure, etc. In addition, the risk of multiple pregnancy and economic time pressure also need to be considered.
Therefore, before couples decide to carry out the second IVF, they should fully understand the impact on the body and the possible risks, and carry out under the guidance of professional doctors.
