1. Indications

The embryo transfer procedure is indicated for patients undergoing assisted reproductive technology, particularly those who have undergone in vitro fertilization (IVF). The following conditions may warrant the use of this procedure:

• Infertility Patients experiencing difficulties in conceiving due to various factors, including age, hormonal imbalances, or unexplained infertility.
• Previous IVF Cycles Individuals who have previously attempted IVF and are seeking to transfer viable embryos from a new cycle.
• Genetic Screening Patients who have undergone preimplantation genetic testing (PGT) to select embryos free of specific genetic disorders.

2. Procedure

The embryo transfer procedure involves several critical steps to ensure the safe and effective placement of embryos into the uterus. Each step is designed to maximize the chances of successful implantation and pregnancy.

• Step 1: Preparation of the Patient Prior to the procedure, the patient is prepared by ensuring that the bladder is full, as this can help in visualizing the uterus during the transfer. The physician may also perform a transvaginal ultrasound to assess the uterine lining and confirm the optimal timing for the transfer.
• Step 2: Embryo Aspiration The physician carefully aspirates the embryos from the culture dish using a specialized catheter. This step requires precision to ensure that the embryos are not damaged during the transfer process.
• Step 3: Catheter Insertion The catheter containing the embryos is gently inserted through the vagina and cervix into the uterine cavity. This step is performed under sterile conditions to minimize the risk of infection.
• Step 4: Embryo Transfer Once the catheter is in place, the physician carefully evacuates the embryos into the uterus. This is done slowly and methodically to ensure that the embryos are deposited in a suitable location for implantation.
• Step 5: Catheter Withdrawal After the embryos have been transferred, the catheter is withdrawn from the uterus, and the procedure is complete. The physician may perform a final ultrasound to confirm the position of the embryos.

3. Post-Procedure

Following the embryo transfer, patients are typically advised to rest for a short period before resuming normal activities. It is common for physicians to recommend avoiding strenuous activities and sexual intercourse for a specified duration to enhance the chances of successful implantation. Patients may also be prescribed progesterone supplements to support the uterine lining and facilitate embryo implantation. Follow-up appointments are usually scheduled to monitor the patient's progress and to conduct a pregnancy test approximately two weeks after the transfer.
