Stage of IVF
With the development of modern medicine, IVF technology has become an important means to help couples who are unable to conceive naturally realize their reproductive dreams. The success of IVF is not achieved overnight, but needs to go through several critical stages. This article will elaborate from four aspects: preparation stage, selection of assisted reproductive technology, embryo transfer and pregnancy detection.
Preparation phase
The preparation stage of IVF is the first and crucial step in the whole process. First, couples should have a comprehensive physical examination, including reproductive system, hormone levels and other aspects, to determine whether it is suitable for IVF technology. Secondly, couples also need to be psychologically prepared, because the success of IVF technology is not 100%, and couples should have the psychological capacity to face possible failures and setbacks. Finally, couples also need to choose appropriate assisted reproductive technology centers, such as Peking Union Medical College Hospital, Shanghai Fudan University Affiliated Obstetrics and Gynecology Hospital, where professional doctors will provide advice and guidance to couples.
In the preparation stage, couples also need to carry out some auxiliary examinations, such as ovarian ultrasound examination, semen analysis, etc., to understand their fertility and determine appropriate treatment plans. At the same time, couples also need to carry out a series of genetic tests to eliminate the risk of genetic diseases. The goal of the preparation phase is to ensure that the couple is in good health and ready for the follow-up assisted reproductive technology.
Selection of assisted reproductive technology
After the preparation phase is completed, the next step is to select appropriate assisted reproductive technology. At present, the commonly used assisted reproductive technologies include in vitro fertilization (IVF) and embryo transfer. The couple and the doctor discuss and decide which technology to use, and determine the scheme according to the specific situation.
In vitro fertilization (IVF) is to combine eggs and sperm in an in vitro culture dish, form an embryo, and then transfer it to a woman's uterus to achieve pregnancy. This technology can effectively solve some infertility problems caused by fallopian tube problems, sperm quality and other reasons.
Embryo transfer is to select high-quality embryos to transfer into the uterus after in vitro fertilization, and realize pregnancy by natural means. Embryo transfer technology can improve the success rate, but it also needs to carefully grasp the opportunity and select the best embryo for transfer.
The selection of assisted reproductive technology needs to take into account the specific situation of the couple, the doctor's suggestions, the development of medical technology and other factors.
embryo transfer
Embryo transfer is one of the core steps of IVF. After in vitro fertilization, doctors will choose the best time for embryo transfer according to the development of the embryo. Embryo transfer is usually carried out at the stage when the embryo develops to 3-5 days.
Embryo transfer is usually carried out through the vagina, and the embryo is transferred into the uterus through a catheter. Doctors need to operate carefully and accurately to ensure the success rate of embryo transfer. After the operation, the couple should pay attention to rest, avoid strenuous activities, and receive relevant drug treatment and monitoring.
Generally speaking, after embryo transfer, it is necessary to wait 10 to 14 days for pregnancy test to confirm whether it is successful. If the test result is positive, it means the IVF transplantation is successful.
Pregnancy test
After the successful transplantation of test tube baby, it will enter the pregnancy period. At this time, the couple needs to receive regular inspection and guidance from the maternity obstetrician to ensure the smooth development of the embryo and the health of the couple.
During pregnancy, the doctor will carry out routine examinations of pregnant women, such as routine blood tests, routine urine tests, and ultrasound examinations to observe the development of the fetus. At the same time, doctors will also provide necessary treatment and guidance according to the specific situation, such as nutrition supplement, weight control, infection prevention, etc.
The goal of pregnancy testing is to ensure the safe and successful completion of IVF pregnancy. If all goes well, the couple will welcome their own baby.
Summary
The success of IVF needs to go through several key stages, such as preparation, selection of assisted reproductive technology, embryo transfer and pregnancy detection. Couples need to carry out comprehensive physical examination and psychological preparation, and carefully consider all factors when selecting appropriate assisted reproductive technology. Embryo transfer is one of the core steps of IVF, and pregnancy testing is the key to ensure the safe birth of IVF. Through scientific technology and the guidance of doctors, couples are expected to realize their reproductive dreams.
