How long is the cycle of IVF?
IVF, also known as artificial assisted reproduction technology, is a method to help couples who cannot conceive naturally achieve fertility through in vitro fertilization or embryo transfer. The cycle of IVF refers to the time from the start of assisted reproduction to successful pregnancy. The cycle of IVF will be described in detail from four aspects.
Women's physical examination and preparation stage
The first stage of the IVF cycle is women's physical examination and preparation. A woman needs to undergo a series of physical examinations, including gynecological examination, breast examination, endocrine examination, etc., to ensure that her physical condition is suitable for IVF. Doctors will develop personalized assisted reproduction programs based on the results of physical examination.
At the same time, at this stage, women also need to prepare their own bodies. They need to maintain good living habits, such as quitting smoking, limiting alcohol intake, eating a balanced diet and exercising moderately. In addition, women also need to avoid tension and anxiety and keep their body and mind relaxed.
The whole women's physical examination and preparation phase usually takes 6-8 weeks, depending on the hospital arrangement and personal physical condition.
Egg retrieval and sperm processing stage
Once the woman has completed the physical examination and is ready, the next stage is egg retrieval and sperm processing. At this stage, women will receive ovulation induction treatment, and use drugs to stimulate ovarian development and increase the number of follicles in the ovary.
After the ovary has developed to a certain extent, the doctor will use ultrasound to monitor the condition of the ovary and determine the best time to take eggs. The collection of eggs is carried out through the technology of vaginal egg retrieval, and the doctor will extract the eggs from the follicle in the ovary.
Similarly, at this stage, the husband or donor of the patient will also provide sperm samples, which will be processed to obtain high-quality sperm for subsequent in vitro fertilization.
In vitro fertilization and embryo culture stage
After treatment of eggs and sperm, the next stage is in vitro fertilization and embryo culture. In the laboratory, doctors place sperm and eggs in culture dishes for in vitro fertilization. Common in vitro fertilization methods include common in vitro fertilization and single sperm injection. In vitro fertilization (IVF), sperm is directly added to the culture dish and naturally fertilized with eggs; Single sperm injection is the injection of a single sperm into an egg.
After fertilization, the doctor will observe and evaluate the development of the embryo. They will select the embryos with the most developmental potential, culture them and prepare them for transplantation.
Embryo transfer and pregnancy testing
After embryo culture, the remaining embryos will be transferred. Embryo transfer is to promote pregnancy by placing an embryo into a patient's uterus. This is a short process that usually takes only a few minutes.
After embryo transfer, women will receive pregnancy tests. This is usually done by measuring the level of HCG (human chorionic gonadotropin) in the blood to determine whether or not you are pregnant. If a woman becomes pregnant successfully, she will enter the normal pregnancy care procedure and receive prenatal examination regularly.
In general, the IVF cycle usually takes 6-8 weeks, depending on personal physical conditions and hospital arrangements. The whole process requires the joint efforts and patience of doctors and patients to achieve a better fertility desire.
Summary
The length of IVF cycle consists of women's physical examination and preparation stage, egg retrieval and sperm processing stage, in vitro fertilization and embryo culture stage, as well as embryo transfer and pregnancy detection stage. The whole process usually takes 6-8 weeks. Women need to undergo physical examination, prepare their bodies, perform ovulation induction therapy and take eggs, then conduct in vitro fertilization and embryo culture, and finally conduct embryo transfer and pregnancy testing. The cycle of IVF is a complex and sophisticated medical technology, which requires the joint efforts and cooperation of doctors and patients.
