Does a mock transfer affect the actual cycle?
No. It takes place in the cycle before your IVF cycle (or at the start of your FET preparation). It has no impact on ovarian stimulation or embryo development.

What is a mock embryo transfer and why is it performed?
A mock embryo transfer is a practice run before your actual transfer — mapping the path your doctor will take. This simple precaution helps improve real transfer outcomes.
What Happens During a Mock Transfer
This is exactly the same process as an actual embryo transfer with one difference, there is no embryo being transferred. This procedure is performed by your doctor inserting a catheter into the uterus through your cervix under ultrasound guidance. Your doctor will be taking notes regarding the position and orientation of the uterus, how easily the catheter can pass through, and any potential anatomical concerns regarding the upcoming transfer.
When Is a Mock Transfer Recommended?
A mock transfer is not always required for patients undergoing IVF treatment. A mock transfer can be very useful for: first-time IVF patients with no medical gynecological history; patients with a narrow cervix or unusual uterine orientation (such as anteverted or retroverted); patients who have previously had difficulties with either their mock or actual transfers; and ERA protocol patients who require endometrial biopsy on the same day.
How It Improves the Real Transfer
On transfer day, your doctor knows exactly how to position the catheter for smooth, atraumatic placement. Difficult transfers, where the catheter meets resistance or has to be repositioned multiple times are associated with lower implantation rates. A mock transfer eliminates most of this risk. Some clinics also use this visit to measure endometrial thickness and confirm readiness for frozen embryo transfer.
Frequently Asked Questions
Q: Does a mock transfer affect the actual cycle?
A: No. It takes place in the cycle before your IVF cycle (or at the start of your FET preparation). It has no impact on ovarian stimulation or embryo development.
Q: Can I go back to work after a mock transfer?
A: Yes immediately. There are no restrictions after a mock transfer other than mild paracetamol if you have cramping.
Q: Is a mock transfer done for every frozen transfer cycle too?
A: Not usually, only if there is a specific reason (first transfer, previous difficulty, change in clinician). It does not need to be repeated once your anatomy is documented.
