Pregnant test tube baby is an important achievement of modern medical technology, which brings good news to those couples who cannot conceive naturally. However, many people have some doubts about the process and time of IVF. Next, we will elaborate on the time of IVF pregnancy from many aspects.
Seek medical advice
The first step of IVF pregnancy is to seek medical advice. Couples need to seek professional medical help after encountering the problem of unable to conceive naturally. They can choose the nearest hospital for consultation, and determine the cause of infertility through physical examination and various examinations. In China, famous hospitals such as Peking Union Medical College Hospital and Shanghai Jiaotong University Medical College Affiliated Obstetrics and Gynecology Hospital have set up professional reproductive medicine centers, which can give patients the most professional guidance and help.
In the process of seeking medical advice, the doctor will work out a reasonable treatment plan according to the specific situation of the couple. For some simple infertility problems, it may be possible to achieve the goal of pregnancy only through some drug treatment; For some complicated cases, IVF technology may be required. Therefore, the treatment time will vary according to individual conditions.
The whole process of seeking medical advice and medicine usually takes several weeks, including hospital visits, preliminary examinations, further special examinations, and development of treatment plans. This stage is the first step of IVF pregnancy.
Ovulation induction and egg collection
Once the IVF technology is decided, the next step is to promote ovulation and collect eggs. At this stage, hormone therapy is needed for the woman to promote ovarian development and expel multiple mature eggs through drugs.
When the ovulation period is approaching, eggs are collected by surgery. This operation is generally non-invasive or minimally invasive and will be performed under anesthesia. Generally, the collection of eggs only takes about half an hour, but the preparation and recovery time may take 2-3 days.
Fertilization and embryo culture
After the eggs are collected, they need to be fertilized with sperm in vitro. This stage usually takes 1-2 days to complete the fertilization. The doctor will cultivate the healthy fertilized eggs selected and incubate them in the medium with good comprehensive conditions. This process takes 4-5 days.
The duration of embryo culture varies from individual to individual, but generally, the most energetic and healthy embryos are selected for transplantation on the third or fifth day, and the remaining high-quality embryos can be frozen for future use.
Embryo transfer and results
Embryo transfer is the last step of the whole process. At this time, the doctor will implant the selected embryo into the woman's uterus. This process usually takes only a few minutes, which belongs to minimally invasive surgery. After the operation, the woman needs to rest and follow the doctor's advice for a period of time.
In general, about two weeks after transplantation, the result of pregnancy can be obtained by blood test. If the pregnancy result is positive, further prenatal examination and observation are required; If the result is negative, it is necessary to carry out treatment again or expand the study in other ways.
In general, the whole process of IVF pregnancy takes several weeks to several months, and the specific time will vary depending on individual differences and medical plans. In the whole process, couples need to pay patience and understanding, and pay close attention to the guidance of doctors to improve the success rate.
From the above description, we can draw the conclusion that the time for IVF pregnancy is a relatively long and patient process, which usually lasts for weeks to months. The time and specific scheme of each stage will be different due to individual differences, which needs to be adjusted and customized according to the specific situation. However, with the continuous progress of medical technology, the success rate of IVF is increasing, which brings hope to those families who are eager to have healthy babies.
