How many days after blastocyst transfer can it be detected?

Update Date: 2024-06-26 Source: Network

It takes 12 to 14 days after blastocyst transfer to detect pregnancy. The blastocyst begins to implant 1 to 2 days after transfer, and then starts to secrete trace amounts of HCG in the body. About ten days after implantation, HCG can be detected in the mother's blood, so a pregnancy test strip can detect a faint double line on the 10th day after blastocyst transfer. However, some people may have a delayed implantation, so it is recommended to take a blood test for HCG to determine pregnancy 12 to 14 days after blastocyst transfer.

Blastocyst transfer technology is now relatively mature, with a success rate of about 50%, which is relatively high. It is a commonly used embryo transfer method in clinical practice, and the implantation rate of the embryo in the uterine cavity is also relatively high. It can effectively help infertile families, reduce multiple pregnancies, and normal pregnancy ectopic pregnancies. The success of blastocyst transfer is closely related to the quality of the blastocyst, the age of the woman, and the environment of the uterine cavity.

Firstly, most women will not have obvious symptoms during the process of implantation. Secondly, some women may experience implantation bleeding due to a transient decrease in estrogen levels, manifesting as light pink or brown bloody secretions lasting for 3-5 days. Thirdly, some women may be sensitive to chorionic gonadotropin and experience early pregnancy symptoms such as nausea, vomiting, loss of appetite, dizziness, fatigue, and weakness.
