Introduction
The embryo typically implants 3 to 5 days after blastocyst transfer. Implantation can be confirmed by testing for urinary or blood human chorionic gonadotropin (hCG) levels 10 days after transfer. Patients should maintain a positive mindset, abstain from sexual intercourse, ensure adequate sleep, and avoid strenuous exercise or heavy physical labor.
Generally speaking, embryo implantation occurs 3 to 5 days after blastocyst transfer. The detailed analysis is as follows:
Blastocyst transfer typically involves patients undergoing the procedure under a doctor's guidance, in which fertilized eggs from in vitro fertilization are cultured outside the body for a certain period until the cells have divided and proliferated to a sufficient number, after which they are re-implanted into the patient's uterine cavity. Once the blastocyst enters the uterine cavity, it begins to implant at a suitable location within 3 to 5 days. Ten days after transfer, implantation can be confirmed by testing urine or blood levels of human chorionic gonadotropin (hCG). During the implantation process, patients should monitor the color of vaginal discharge and their own physical condition; if severe discomfort occurs, medical attention should be sought promptly.
During this period, patients should maintain a positive mindset and avoid anxiety. Sexual intercourse should be avoided, and adequate sleep must be ensured. Strenuous exercise and heavy physical labor should also be minimized. Additionally, a light diet is recommended, with increased intake of fresh vegetables and fruits, while spicy and irritating foods should be avoided.
