Calculation method of IVF pregnancy
With the development of technology, IVF has become the gospel of many infertile couples. The improvement of IVF success rate cannot be separated from accurate pregnancy calculation method. This article will elaborate on the calculation method of IVF pregnancy from four aspects: cycle monitoring, follicle observation, embryo transfer and HCG monitoring.
Periodic monitoring
Periodic monitoring is the first step of IVF pregnancy calculation, aiming to determine the accurate time of female ovulation. Doctors usually use a variety of methods to monitor the cycle, including menstrual records, basal body temperature and urine ovulation test paper. First of all, women need to record their menstrual date to understand the length of their cycle. Then, by measuring the basic body temperature every morning, we can find that the increase in body temperature is a sign of ovulation. Finally, the urine ovulation test paper is also a simple and effective method to monitor ovulation. Women can use the test paper a few days before and after the expected time of ovulation, and judge whether ovulation occurs according to the color changes displayed on the test paper.
On the basis of periodic monitoring, doctors can formulate the next treatment plan according to the ovulation time, including drug treatment and assisted reproductive technology.
Follicle observation
Follicle observation is a key link in IVF pregnancy calculation. The follicle is the main physiological structure of women before ovulation. By observing the size and number of follicles, we can judge the ovulation of women. The common observation methods of follicles include ultrasonic examination and blood hormone detection.
Ultrasonography is a non-invasive inspection method, which uses ultrasonic equipment to observe the condition of follicles in the ovary. Doctors can judge whether a woman is about to ovulate according to the size and number of follicles. In addition, blood hormone detection is also a commonly used method to observe follicles, including detection of luteinizing hormone and ovulatory stimulating hormone levels. These test results can help doctors predict the time of ovulation and make appropriate treatment plans.
embryo transfer
Embryo transfer is a key step in IVF pregnancy calculation. After the egg and sperm combine, the embryo will develop in a culture dish for several days, and then be transplanted into a woman's uterus. Doctors usually determine the best transfer time according to the time when the egg and sperm combine and the development of the embryo.
After embryo transfer, women need to take proper rest and take medicine prescribed by doctors to promote implantation. Within a few weeks after transplantation, women can judge whether they are pregnant according to their body reactions, including breast pain, nausea and vomiting. In addition, nurses or doctors also conduct regular HCG monitoring to determine whether or not they are pregnant.
HCG monitoring
HCG monitoring is an important part of IVF pregnancy calculation. HCG is a hormone produced by embryo, and its level will gradually rise after pregnancy. By regularly detecting the changes of HCG levels in urine or blood, we can judge whether a woman is pregnant.
For IVF infants, HCG monitoring usually starts 10-14 days after embryo transfer. The doctor will instruct women to have a HCG test every few days until they can confirm pregnancy through ultrasonic examination. The results of HCG monitoring are very important to ensure the success of IVF pregnancy.
summary
The calculation methods of IVF pregnancy include cycle monitoring, follicle observation, embryo transfer and HCG monitoring. By accurately calculating the time of pregnancy, infertile couples can be helped to achieve their reproductive aspirations. Different calculation methods complement each other and provide reliable support for the successful pregnancy of IVF.
