In vitro fertilization is a common method that is often chosen for the treatment of rare late. The beta hCG test after 14 days of embryo transfer is very important to help determine whether the conception process is successful or not.
1. In vi vism fertilization
In vi vism in vism fertilization is a rare treatment in which fertilization takes place in vi test tubes, after the embryo forms will be transferred into the woman's uterus to continue development.
In vism in vism fertilization usually undergoes the following steps:
- Examination and assessment of the couple's state of sexual health. The wife will be given genital hormone dosing tests, blood tests to check for infectious diseases and gynecologic ultrasound. Meanwhile, the husband will do tests to assess the quality of sperm and test for infectious diseases.
- The wife will be injected with ovarian stimulants for 9-11 days. The process of ovarian stimulation should be closely monitored to determine the right time for ovulation injections.
- After 36-40 hours of ovulation, the wife will be anesthetic to poke the eggs while the husband will be taken sperm.
- Eggs and sperm will be transferred in viinal fertilization to create embryos. This culture usually takes place 2-5 days before transferring the embryo into the wife's uterus. The fertilization process can get many quality embryos, some of which will be transferred into the uterus, some of which will be frozen so that they can be used in later embryo transfers.
- Embryo transfer: As a very important step in the process of fertilization, the doctor will transfer the embryo when the lining of the uterus has sufficient thickness and good quality, favorable for development when the embryo is placed in the uterus.
- Perform a beta hcg test after 14 days of embryo transfer.
- Monitor the pregnancy if the fertilization process is successful.
2. hCG beta test after 14 days of embryo transfer
2.1. What is hCG hormone?
HCG hormone (Human Chorionic Gadonatropin) is a sexually directed hormone that is secreted very early in pregnancy, as soon as fertilized eggs nest in the lining of the uterus, so the hormone hCG is an important only point that helps determine pregnancy , in addition to monitoring hCG levels during pregnancy that help monitor the development of pregnancy.
The normal human hCG concentration is 25 mUI/ml, if the concentration is < 5 mUI/ml, ở phụ nữ có thai > between 6-24 mUI/ml, the pregnancy is unknown, additional tests and monitoring are required to determine. HCG levels are usually lower than normal pregnancy in cases of miscarriage, discontinued pregnancy, extrapypypies. High hCG levels in cases of multi-pregnancy, egg-incubating, extrapervical pregnancy,…
2.2. The role of hCG beta testing after 14 days of embryo transfer
Normally after 14 days of embryo transfer, the wife will go to the hospital to check the beta hCG concentration, if the hCG beta concentration is higher than 25mUI/ml is already pregnant. Because the concentration of hCG in the early stages of pregnancy increases very quickly, usually the hCG concentration will double every 48-72 hours, so if after two days of reviewing the beta hCG concentration increases by about 1.5 times or more compared to the first time, it proves that the pregnancy is developing.
If the level of beta hCG increases low accompanied by abnormal signs such as prolonged smoldering abdominal pain, vaginal bleeding,… it is possible that the embryo is regressing, the ability to hold the pregnancy is low. However, if actively handled by doctors and after 48 hours of re-testing, the hCG concentration at least doubles, there is still hope of retaining the pregnancy.
If the results of the beta hCG test after 14 days of embryo transfer are high compared to normal levels, then it is likely that the multi-pregnancy will be carried out, however during the period of pregnancy waiting for an ultrasound, if there are signs such as vaginal bleeding with abdominal pain, it is necessary to go to the hospital for a timely examination to exclude the possibility of an extrasterility pregnancy.
If hCG test results after 2 days do not increase or decrease, follow-up should be continued. If the hCG concentration decreases < 5mUI/ml thì đã bị sảy thai. In this case, the frozen embryos will be further transferred into the uterus in the next cycles.
After the embryos implanted in the uterus have developed successfully, the pregnant woman needs to spend a lot of time resting, eating enough substances, exercise gently appropriately and especially having to have an ultrasound and regular pregnancy examination according to the doctor's appointment to ensure the pregnancy process is safe.
Share99 IVF Assisted Reproduction Center was established in November 2014 with modern facilities and a team of highly-level experts including professors, doctors, doctors at home and abroad. To date, the center has assisted in reproduction for more than 1000 rare couples across Vietnam with a success rate of 45%-50%, this success rate is comparable to developed countries such as the US, UK and Australia,..
