Last updated: · · Based on data from 196+ surrogacy agency compensation packages

An embryo transfer is the medical procedure where a fertilized embryo is placed into a surrogate's uterus. It's done by a reproductive endocrinologist at a fertility clinic and is typically a quick, minimally invasive outpatient procedure.

Why Embryo Transfer Matters for Surrogates

Transfer day is one of the most significant milestones in your journey. It's when the biological process begins and when you start earning your embryo transfer fee. Understanding what to expect helps reduce anxiety and prepares you for the two-week wait that follows.

How Embryo Transfer Works in Surrogacy

The transfer itself takes about 15–30 minutes. You'll typically:

The embryo transfer fee is typically paid regardless of whether the transfer results in pregnancy.

Real-World Example

Most fertility clinics transfer one embryo at a time (single embryo transfer, or SET) to reduce multiples risk. Your contract will specify whether single or double embryo transfers are agreed upon, and intended parents may have input depending on the number and quality of available embryos.

Frequently Asked Questions

What is an embryo transfer in surrogacy?
An embryo transfer is the medical procedure where a fertilized embryo is placed into the surrogate's uterus using a thin catheter. It's a brief, usually painless procedure performed at a fertility clinic, typically taking 10–15 minutes.
How long does embryo transfer take?
The actual transfer procedure takes about 10–15 minutes. You'll need to arrive early for preparation and may rest briefly afterward. Most surrogates can resume normal activities within a day or two, though some doctors recommend a day of rest.
Does embryo transfer hurt?
Most surrogates describe embryo transfer as painless or mildly uncomfortable — similar to a Pap smear. No anesthesia is typically needed. Some women experience light cramping afterward, which is normal.
How soon after embryo transfer do you know if you're pregnant?
A blood pregnancy test (beta-hCG) is typically done 10–14 days after embryo transfer. This is more accurate than home pregnancy tests. If positive, a follow-up ultrasound at 6–7 weeks confirms a heartbeat and viable pregnancy.
