How long does IVF pretreatment take?
The pretreatment of IVF is a part of assisted reproductive technology. The eggs and sperm are artificially combined and cultured. Finally, healthy embryos are transferred to the female uterus to achieve the purpose of pregnancy. This technology has been widely used in modern medicine. However, the pretreatment process of IVF needs to go through many important steps. Therefore, the pretreatment time will vary from hospital to hospital and from case to case.
1. Diagnosis and evaluation:
The first step of IVF pretreatment is to conduct a comprehensive physical examination and health assessment for both spouses. The doctor will conduct gynecological examination for women, including the assessment of uterine shape and ovulation function, and semen analysis for men. In addition, the genetic disease and venereal disease examination of both spouses is also essential. This step usually takes 2-3 weeks.
After completing the physical examination, the doctor will formulate a personalized treatment plan based on the examination results of both the husband and wife, and consult and answer possible problems. This process usually takes 1-2 weeks.
In summary, the diagnosis and evaluation phase usually takes 3-5 weeks.
2. Ovulation promotion and ovarian stimulation:
The second step of IVF pretreatment is to stimulate ovarian growth and ovulation by using ovulation promoting drugs. The use of these drugs may require multiple injections within a month, combined with regular ultrasound and blood tests. By monitoring the drug response, doctors can determine the best time to collect eggs. The duration of ovarian stimulation varies from case to case, about 2-4 weeks.
During ovarian stimulation, the doctor will conduct regular ultrasound examination to observe the number and size of follicles. Once the follicle reaches the proper size, the doctor will recommend the next step of pre fertilization examination.
Therefore, the duration of ovulation induction and ovarian stimulation is usually about 2-4 weeks.
3. Pre fertilization inspection:
Pre fertilization examination is one of the core processes of IVF pretreatment. In this step, doctors will collect mature eggs from women and sperm from men. When eggs and sperm combine, doctors will cultivate them in the laboratory to observe the development of the embryo.
The examination before fertilization takes about 3-5 days. During this period, doctors will select the best embryo for transplantation according to the development of the embryo.
4. Embryo transfer and observation:
On the 3rd to 5th day after fertilization, the doctor will select the best embryo to transfer to the female uterus. This process usually requires no surgery, but a simple operation to pour the embryo into the uterus.
After embryo transfer, doctors will observe for a period of time to ensure that the embryo is successfully implanted and continues to develop into a baby. This observation usually lasts for 1-2 weeks.
Summary:
To sum up, the pretreatment time of IVF varies with the specific operation of each stage and individual cases. Generally speaking, the whole pretreatment process from diagnosis and evaluation to embryo transfer and observation may take 8-12 weeks. However, the hospital's professional experience, technical level and the matching degree of individual cases will also have an impact on time. Therefore, it is recommended that couples discuss in detail with the doctor before choosing a hospital and starting pre-treatment, and understand the specific schedule.
