Fresh Embryo Transfer

Fresh Embryo Transfer – Comprehensive Guide

What is Fresh Embryo Transfer?

Fresh embryo transfer is the process of transferring embryos obtained during IVF treatment into the uterus within the same menstrual cycle, without freezing.

When is it Performed?

It is usually performed on day 3 or 5 (blastocyst stage) after the egg retrieval (OPU) procedure.

How Does the Process Proceed?

It proceeds as follows: egg retrieval → fertilization → embryo development → transfer on the appropriate day.

Advantages

• Shorter duration
• No additional freezing-thawing process
• Provides quick results in suitable patients

Disadvantages

• Endometrium may not always be optimal
• Not recommended for patients at risk of OHSS

Who is it Suitable For?

• Patients with low OHSS risk
• Those with an endometrium of appropriate thickness
• Those with a balanced hormonal environment

Transfer Procedure

It is painless and usually does not require anesthesia. It is performed with a thin catheter under ultrasound guidance.

Luteal Phase Support

Progesterone support is given after transfer. It supports embryo implantation.

Pregnancy Test

A blood test is performed approximately 10–12 days after the transfer.

Success Rate

It varies depending on patient age, embryo quality, and endometrial status.

Fresh vs. Frozen Transfer

In some patients, frozen embryo transfer may be more advantageous. This decision is made on an individual basis.

Conclusion

Fresh embryo transfer is an effective method with appropriate patient selection, but it may not be the ideal option for every patient.
