What is the Desired Level of hCG After 13 Days of Transplantation?
Some women cannot conceive naturally due to various reasons such as advanced age or reproductive system diseases. In such cases, in vitro fertilization (IVF) can be considered as a method of assisted reproduction. For couples eager to have children, IVF may be a viable option. During the treatment process, the level of hCG (human chorionic gonadotropin) is an important indicator. Let's take a look at the hCG levels that are considered satisfactory on day 13 of embryo transfer.
1. hCG Levels on Day 13 of Embryo Transfer
Around 13 days after blastocyst transfer, the hCG level should reach above 100 to indicate successful implantation. This value varies from person to person, ranging from tens to hundreds. The key factor after blastocyst transfer is whether the hCG level doubles, which often indicates good embryonic development. Additionally, a vaginal ultrasound can be performed 20 days after transfer to assess blastocyst development. Continued medication to support pregnancy is also recommended after embryo transfer.
2. When Can Embryo Implantation Be Detected?
Generally, embryos transferred into the female uterus will float freely for about 7 days to find a suitable implantation site. If the embryo fails to find a suitable site, implantation may fail. The success or failure of embryonic implantation is closely related to the quality of the embryo. If the embryo quality is good enough, it may successfully implant on the same day as the blastocyst transfer, although this scenario is relatively rare.
3. When Does Blastocyst Implantation Successfully Occur?
The earliest blastocyst implantation can be detected is around day 7, but this requires sufficiently good blastocyst quality. Typically, it takes at least 14 days after embryo transfer to detect it through blood tests. The probability of detecting it in the blood on day 7 of transfer is relatively low, but it is still possible. Therefore, the benefit of IVF is that by transferring the best-quality embryos into the female body, the success rate is significantly higher.
