Blastocyst Transfer Procedure in Artificial Cycle

Artificial cycle embryo transfer refers to the process of using medication to prepare the endometrium, allowing it to reach an adequate thickness before transferring laboratory-cultured embryos into the uterine cavity. The specific steps are as follows:

1. Days 2–13 of the menstrual cycle: Based on individual conditions, local medications are administered to supplement estrogen and progesterone.

2. Days 14–15 of the menstrual cycle: Evaluate endometrial thickness and hormone levels to confirm they meet the criteria for embryo transfer.

3. Day 17 of the menstrual cycle: The doctor thaws 1–3 embryos and transfers them into the patient's uterus.

4. Approximately ten days after transfer, a pregnancy test is performed to determine whether the transfer was successful.

5. After confirming pregnancy, regular blood tests are conducted to monitor human chorionic gonadotropin (hCG), estrogen, and other hormone levels. A follow-up ultrasound is performed three weeks later to confirm normal fetal development.

After the transfer, patients should rest adequately, maintain a balanced diet, and avoid raw, cold, spicy, or irritating foods. Artificial cycle embryo transfer should be performed at a reputable medical facility under the care of qualified specialists.
