What are the injection time options for IVF?
IVF is a method to help infertile couples realize their dreams of fertility through artificial pregnancy technology. In the whole process of IVF, injection is a very important part. It can help control ovarian function, maintain luteal function, and regulate progesterone levels. Next, we will discuss the injection time of IVF from different perspectives.
1. Preparation before pregnancy cycle
Before receiving IVF treatment, women need to undergo a series of physical examinations to ensure their health. The injection at this stage usually includes the injection of ovulation promoting drugs. The purpose of ovulation promoting drugs is to make the ovary produce more eggs and increase the chance of pregnancy. The injection time is selected according to the specific hospital's plan, which usually starts on the second day of the menstrual cycle and lasts for 5-12 days.
During this period, patients need to inject drugs at a specific time every day according to the doctor's instructions. These drugs are generally given by subcutaneous injection, which is simple and less painful.
After drug injection, ultrasound monitoring is usually required to determine the growth of follicles. The doctor will adjust the dosage of drugs according to the ultrasound results to ensure that the ovarian response is appropriate.
2. Control during pregnancy
After the egg develops to a mature stage, the ovulation promoting drugs are usually stopped or the dosage is halved. At this time, the injection time will change. Generally speaking, the doctor will make an appointment for the operation the next day after stopping the medicine. At this time, patients need to inject drugs to maintain luteal function on time to promote the smooth progress of implantation.
The injection time may be adjusted in the first three months after conception. Some hospitals will conduct the first blood HCG test 14-15 days later to confirm whether the implantation is successful. If the test result is normal, the doctor will adjust the dose and time of injection according to the specific situation. Usually, at least 1-2 injections per week are necessary.
In addition, regular ultrasound examination is required to monitor the development of embryos. Doctors will adjust the use and dosage of drugs according to the ultrasonic results.
3. Management during pregnancy
Once IVF implantation is successful, women will enter the pregnancy management stage. The injection time is usually within the first 6-8 weeks after implantation. The injection at this stage is mainly to maintain the luteal function and avoid the risk of abortion due to the decrease of progesterone level.
The injection time is usually every night to ensure the stability and effect of the drug. The duration is determined according to the scheme of the specific hospital, usually 6-8 weeks.
In the process of pregnancy management, regular prenatal examination and ultrasound examination are also required to ensure the healthy development of the fetus. The doctor will adjust the dosage and use time of drugs according to the examination results.
4. Precautions for injection time
During IVF treatment, the time of drug injection is very important, which needs to be carried out in strict accordance with the doctor's instructions. If you miss the injection time, you should consult your doctor in time and do not adjust the dose and use time by yourself.
At the same time, patients need to master the correct injection skills to ensure the accurate injection of drugs. During the injection process, the injection site should be kept clean and disinfected to avoid the risk of infection.
In a word, the injection time of IVF includes the preparation before the pregnancy cycle, the control during pregnancy, and the management during pregnancy. There are specific arrangements and precautions for injection time at each stage. Patients should strictly follow the guidance of doctors to ensure the smooth progress of treatment.
Summary:
The injection time of test tube babies covers several stages, such as ovulation promoting drug injection before the pregnancy cycle, luteal function maintaining drug injection during pregnancy, and pregnancy management. There are specific arrangements and precautions for injection time at each stage, and patients need to strictly follow the guidance of doctors. Correct injection time and techniques are crucial to the success rate of IVF and the health of mothers and infants. Therefore, patients should maintain good cooperation and communication throughout the process, and report any problems and conditions to doctors in time to ensure the smooth progress of treatment.
