How long can the frozen embryo of test tube baby be implanted after transplantation

Test tube baby is an important breakthrough in modern medical technology. For some infertile couples, it is the gospel of family building. In the process of IVF, embryo transfer is an important link. However, many people have doubts about how long it will take for IVF frozen embryos to be implanted. This article will answer this question from various angles.

Time node after embryo transfer

The time nodes of IVF frozen embryo transfer can be divided into pre implantation stage, implantation stage and post implantation stage.

Preimplantation: on the first or second day after embryo transfer, the embryo enters the uterine cavity; On the 3rd and 4th days, the embryo began to become a blastocyst; On the 5th to 6th day, the blastocyst further developed into a trophoblastic blastocyst.

Embryo implantation stage: after the successful formation of the blastocyst, it enters the implantation stage. 7-8 days after embryo transfer, the embryo enters the endometrium and starts implantation.

Later stage of embryo implantation: after successful implantation, the embryo begins to secrete human chorionic gonadotropin (hCG), and produces blood circulation, which continues to develop into an embryo.

Factors affecting embryo implantation

The time of implantation after IVF frozen embryo transfer is affected by many factors.

Endometrial state: The good state of the endometrium plays a vital role in the implantation of the embryo.

Embryo quality: the quality of the embryo is also one of the key factors affecting the implantation time. Higher quality embryos are more likely to be implanted successfully in a short time.

Patient's physical condition: the patient's physical condition, age, lifestyle, etc. will also affect the time of implantation. Young and healthy women usually have a higher success rate of embryo implantation.

Actual case analysis

Taking a well-known hospital in China as an example, the hospital carries out a large number of IVF embryo transfer operations every year, and continues to track cases. In an investigation, the following situations were found:

Situation 1: On the 7th day after embryo transfer, about 50% of the patients began to show mild breast swelling, breast pain and other symptoms, which is a possible signal for embryo implantation.

Situation 2: On the 9th day after embryo implantation, about 80% of the patients had mild bleeding, which was difficult to detect in ordinary life.

Situation 3: On the 14th day after embryo transfer, about 90% of the patients showed positive urine test results, that is, signs of early pregnancy.

summary

The time of embryo implantation after IVF embryo transfer varies from individual to individual. Generally speaking, there may be some signs or test results showing signs of implantation on the 7-14 days after embryo transfer. However, delayed implantation may occur in some cases. For IVF couples, keeping an optimistic attitude, following the doctor's advice, and reasonably arranging life and rest will help improve the probability of successful implantation.
