How long does it take for test tube baby Beiyi to complete?
IVF is an assisted reproductive technology, which means that in the process of IVF, sperm and egg are combined, then the embryo develops to a certain stage, and finally the embryo is transferred to the mother's uterus. Compared with natural pregnancy, the process of IVF is more complex and time-consuming. The time of IVF will be different in different hospitals and individuals. The following is a detailed description of how long it takes for IVF Beiyi to complete it from four aspects.
Initial diagnosis and examination
Before IVF, you need to go to a regular reproductive medical center for initial diagnosis and comprehensive examination. Initial diagnosis usually includes doctors' detailed understanding of both husband and wife, personal and family medical history, infertility, etc. The comprehensive examination includes the semen analysis of the man, the ovarian function test of the woman, and the examination of the uterus and fallopian tubes. This phase will take days to weeks to complete.
At the initial diagnosis and examination stage, doctors will develop personalized treatment plans based on the examination results, including which assisted reproductive technology to use, medication, treatment cycle, etc. The time of this stage is the key to determine the follow-up treatment plan.
Ovulation induction and egg retrieval
In the process of IVF treatment, in order to obtain enough eggs, the woman needs to receive ovulation induction treatment. Doctors will prescribe ovulation promoting drugs according to personal conditions to promote follicular development and ovulation. The process of ovulation induction usually lasts for 10-14 days. During this period, patients need to conduct regular ultrasonic examination and blood testing to determine the development of eggs.
When the follicles reach the proper size and number, the doctor will arrange an egg retrieval operation. Egg retrieval is usually performed 36 hours after ovulation, and needs to be performed in the hospital. The operation time is relatively short, usually between 15-30 minutes. Local anesthesia is required before egg retrieval, and bed rest is required after the operation. The duration of the whole ovulation induction and retrieval phase is about 2-3 weeks.
Fertilization and culture
The removed eggs will be fertilized with sperm in vitro. The common fertilization methods are conventional fertilization and micro implantation fertilization. Conventional fertilization is to culture each egg and sperm in a culture dish and wait for fertilization to occur. Micro implantation fertilization is to inject a single sperm into the egg to promote fertilization. After fertilization, the embryo will continue to be cultured in the culture dish until it reaches the appropriate development stage.
The culture cycle of the embryo is usually 3-5 days, during which the doctor will constantly observe the development of the embryo and evaluate the quality of the embryo. Generally, high-quality embryos will be selectively transplanted into the mother's uterus. The whole period of fertilization and culture is about 1-2 weeks.
Embryo transfer and pregnancy observation
Embryo transfer is to place the cultured embryos into the mother's uterus through hysteroscopy or wire guide tube. This process is usually simple and takes several minutes to half an hour. After embryo transfer, patients need to rest and observe to avoid strenuous exercise and emotional fluctuations.
Positive differential diagnosis after transplantation can usually occur 7-14 days after transplantation. Later, the patient will conduct pregnancy observation, including blood pregnancy test and ultrasound examination, to determine whether the embryo is successfully implanted and developed. If the pregnancy is successful, the patient will enter the pregnancy period and need to continue to receive the doctor's guidance and pregnancy care.
summary
The completion time of test tube baby Beiyi is a long process, which takes about 6-8 weeks. The initial diagnosis and examination phase takes several days to several weeks, the ovulation induction and egg retrieval phase is 2-3 weeks, the fertilization and culture phase is 1-2 weeks, and the embryo transfer and pregnancy observation phase is weeks to months. Each stage is very important, and patients need to work closely with doctors and follow their guidance and suggestions.
During IVF treatment, patients need to be patient and positive to minimize the impact of pressure and negative emotions. At the same time, choosing a formal reproductive medical center and seeking the help and guidance of professional doctors can improve the chances of success of IVF.
