What is the time period of IVF?
Test tube baby is a kind of medical assisted reproductive technology. Many couples choose test tube baby as their way to realize their reproductive dreams. However, how long is the time period of IVF and how many attempts are needed? The following will elaborate on this issue from four aspects.
Embryo culture and screening
In the process of IVF, eggs and sperm need to be obtained first. Then, in the laboratory, the doctor combines the egg with the sperm to form a fertilized egg. Next, the fertilized eggs need to be cultured and screened. Generally, embryos need to be cultured in the laboratory for 3-5 days to ensure that they have sufficient development potential. In the process of embryo culture, the doctor will carefully observe the development of the embryo and select the well developed embryo for subsequent transplantation.
The whole process of embryo culture and screening usually takes 5-7 days. Doctors will decide the best time for transplantation according to the development and quality of embryos, so as to improve the success rate of IVF.
embryo transfer
Embryo transfer is a key step in the process of IVF. Before transplantation, doctors will prepare the endometrium to create the best breeding environment. Endometrial preparation usually requires taking hormone drugs to adjust hormone levels and promote endometrial thickening, thus increasing the chances of successful embryo implantation.
Once the endometrium is ready, the doctor will select a well developed embryo for transplantation. Embryo transfer is a simple and rapid process, which usually takes only a few minutes. The doctor will use a catheter to carefully transfer the embryo into the uterine cavity. After transplantation, women need to rest and recover to increase the chances of embryo implantation.
Number of pregnancy tests and attempts
After embryo transfer, pregnancy test is carried out about 14 days later to confirm whether the pregnancy is successful. This can be determined by the level of progesterone in blood or urine. If the result shows that the pregnancy is successful, you will start the monitoring and nursing during pregnancy.
However, if the attempt fails, that is, the pregnancy fails, the couple can choose to try IVF again. The number of attempts varies depending on the couple's personal circumstances. Some couples may succeed in their first attempt, while others may need to try many times to achieve their fertility goals. Doctors will make personalized treatment plans according to the specific conditions and needs of each couple.
summary
The time period and the number of attempts of IVF vary according to the individual situation of the couple. Embryo culture and screening usually take 5-7 days, and embryo transfer only takes a few minutes. The number of attempts depends on the pregnancy test results. Some couples may succeed once, while some couples may need to try many times. However, by cooperating with doctors and fully understanding their personal situation and the hospital's actual operation process, couples can better understand the time cycle and number of attempts of IVF and make more intelligent decisions.
