What is the time period of IVF?
Test tube baby is an assisted reproductive technology, which combines sperm and eggs in vitro, cultivates them into embryos, and then implants the embryos into women's uterus to achieve the purpose of pregnancy and fertility. The time cycle of IVF is a complex and long-term process, and I will elaborate from different stages below.
Phase I: Assessment and preparation of women's reproductive system
The first condition for successful IVF is an appropriate female reproductive system. At this stage, women need to conduct a detailed reproductive system assessment, including tubal patency, cervical status, endometrial conditions, etc. In addition, women also need to carry out some relevant tests, such as blood routine test, hepatitis B virus, AIDS, etc., to ensure that their physical health meets the requirements for IVF.
According to the arrangement of the hospital and the physical condition of the women, this stage usually lasts for 1-2 months. If there are some physiological problems, additional surgery or treatment may be required, and the time may be prolonged.
Stage II: Egg taking and sperm collection
At this stage, women need to inject ovulation promoting drugs to increase the number of eggs. The doctor will monitor the development of the follicle, and when the follicle develops to the appropriate size, an egg retrieval operation will be performed. The operation is a minimally invasive operation, which is usually performed under general anesthesia.
Men need to collect semen, usually by manual stimulation or using a sperm extractor. This process is usually fast, but some men may need to collect more than once to get enough sperm.
This stage usually lasts for 2-3 weeks, and the specific time will vary according to personal conditions.
Stage 3: In vitro fertilization and embryo culture
The obtained eggs and sperm are fertilized in vitro, that is, sperm is injected into the eggs. After that, the embryos will be cultured in a laboratory dish. The culture time depends on the embryo quality, usually 3-5 days.
At this stage, doctors will select the best embryos for transplantation according to the embryo quality assessment. If several embryos are successfully cultured, they can be frozen for future use.
The whole process of IVF and embryo culture usually takes about one month.
Stage 4: embryo transfer and pregnancy observation
The selected embryo will be inserted into the woman's uterus through a thin tube at a specific time point. This process is usually painless and can be completed within 20 minutes.
After transplantation, women need to take some drugs to regulate hormone levels and promote implantation and embryo growth. Within 14 days after transplantation, blood tests will be performed to determine if pregnancy has occurred.
The whole process of embryo transfer and pregnancy observation takes about two months.
How to plan the time of IVF?
The time planning of IVF is a comprehensive result of personal conditions and doctor's guidance. Generally, women are advised to consult and check in advance, and make time plans according to their personal conditions.
First, determine whether you meet the conditions for IVF, which can be known through relevant inspection and evaluation. If there are some physiological problems, it may be necessary to carry out surgery or treatment in advance to ensure that the health meets the requirements.
Secondly, according to the doctor's guidance, determine the time point for egg collection and sperm collection. This process requires women to inject ovulation promoting drugs, so it needs to plan a time several weeks in advance.
In addition, determine the time of IVF and embryo culture with the doctor. Generally, the whole process takes about a month.
Finally, determine the time of embryo transfer. This needs to be arranged according to women's cycle and embryonic development.
To sum up, the time cycle of IVF varies according to individual circumstances, and generally takes about two to three months. A time plan should be made according to the doctor's guidance and personal conditions to ensure the smooth progress of each stage.
summary
The time cycle of IVF mainly includes the preparation of women's reproductive system assessment, egg retrieval and sperm collection, IVF and embryo culture, embryo transfer and pregnancy observation.
Women need to make sure that they are suitable for IVF through evaluation and examination, and carry out some additional surgery or treatment to ensure that their physical health meets the requirements.
It usually takes several weeks to collect eggs and sperm. Women inject ovulation promoting drugs to increase the number of eggs. Men usually collect sperm quickly.
The process of IVF and embryo culture usually takes about a month. The embryo will be cultured in the laboratory dish, and the doctor will select the best one for transplantation according to the quality of the embryo.
Embryo transfer and pregnancy observation usually take about two months. Women need to take drugs to regulate hormone levels to promote embryo growth and implantation.
According to personal conditions and doctor's guidance, develop a suitable time plan for IVF to ensure the smooth progress of each stage.
