What Is Fetal Heartbeat in Surrogacy?

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

Detection of a fetal heartbeat on ultrasound — typically around 6–7 weeks of pregnancy — is one of the most significant medical and financial milestones in a surrogacy journey. It's when base compensation usually begins.

Why Fetal Heartbeat Matters for Surrogates

The heartbeat confirmation is the trigger for base compensation in most surrogacy contracts. Once the heartbeat is seen, your monthly base payments begin from the escrow account. It's also the moment many intended parents allow themselves to truly celebrate — making it emotionally significant for everyone involved.

How Fetal Heartbeat Works in Surrogacy

At around 6–7 weeks of pregnancy (about 3–4 weeks after a positive beta), you'll have a transvaginal or abdominal ultrasound at the fertility clinic. The intended parents may be present (in person or via video). The fetal heartbeat is detected as a flickering movement on the ultrasound screen — usually at a rate of 100–170 beats per minute.

Real-World Example

Most contracts specify something like: "Base compensation payments of $X per month shall begin upon confirmed fetal heartbeat on ultrasound, payable monthly from the escrow account." After heartbeat confirmation, your first monthly payment typically arrives within 7–14 days.

Frequently Asked Questions

When is the fetal heartbeat detected in surrogacy?
A fetal heartbeat is typically detected on ultrasound around 6–7 weeks of pregnancy (about 4–5 weeks after embryo transfer). This is a major milestone in surrogacy — it triggers the start of monthly base compensation payments from escrow.
Why does fetal heartbeat matter for surrogate pay?
In most surrogacy contracts, monthly base compensation begins after a confirmed fetal heartbeat. This milestone proves the pregnancy is viable and triggers the main payment schedule. Before heartbeat, surrogates receive transfer fees and early milestone payments.
What happens if no heartbeat is detected?
If no heartbeat is detected at the expected time, the clinic may schedule a follow-up ultrasound a week later. If confirmed non-viable, the surrogate keeps all compensation earned to that point. Your contract should specify financial provisions for this scenario.
