Egg donors are people with full lives, and sometimes life changes after a donor has been matched. When a donor withdraws before retrieval, intended parents who have planned their calendars, finances and hopes around that cycle can feel as if the ground has shifted.
If this has happened to you, or you want to plan for the possibility, this guide explains what happens next, why donors back out, and the options and protections that help you keep moving toward your family.
The short answer
If an egg donor backs out, the cycle stops before egg retrieval, and most intended parents rematch with another donor or move to frozen donor eggs.
Donors have the right to withdraw at any point before retrieval, so your protection comes from clear agreements, your agency's rematch policy and a backup plan.
What happens if an egg donor backs out?
When an egg donor backs out, the planned cycle is cancelled, and your agency and fertility clinic walk you through what comes next. Any medications that have not started are stopped or never begun, the clinic adjusts your own schedule, and your agency reviews your options and your agreement with you.
What it means for you depends largely on timing:
| When the donor withdraws | What it usually means for intended parents |
|---|---|
| Before medical screening | Least disruption, since you can choose another donor quickly |
| During screening | You have spent some time, and some screening costs may already be paid |
| After legal agreements, before medications | Your clinic calendar resets, and escrow and agency policies decide what is refunded |
| During ovarian stimulation | The cycle is cancelled, and your agreement sets any partial payment to the donor |
| After egg retrieval | Donors no longer control retrieved eggs unless the contract provides otherwise |
Can an egg donor change her mind?
Yes, an egg donor can change her mind. The American Society for Reproductive Medicine (ASRM) states that donors "may withdraw from the donation process at any point," and that once eggs are retrieved they "no longer have dispositional control" over them unless a valid contract provides otherwise.1
ASRM also acknowledges that "occasionally egg donors will discontinue participation for personal or medical reasons." For that reason, it recommends a written advance directive covering partial payment to donors when a donor or doctor halts treatment before retrieval.1 Ask your agency how its agreements handle this before you sign.
Why do egg donors back out of a cycle?
Egg donors usually back out because of a major life change or a medical reason, and it is rarely a sign that a donor took the commitment lightly.
Personal reasons
Common personal reasons include a family emergency, a sudden move, a new job or a change in a relationship. One proven donor, who had already completed several cycles, withdrew just days before she was due to start medications. She had recently divorced and learned that her employer was relocating her out of state within two weeks. As a single parent, she needed to find housing and daycare in a new city, and she knew she could not give the cycle the attention it required without putting her health at risk.
The intended parents were disappointed, but they respected her decision. They also recognized that going ahead under that much stress was not good for the donor or the cycle.
Medical reasons
Sometimes the decision is made by a doctor. Screening can reveal a genetic or infectious disease result that rules a donor out, and during stimulation a clinic may stop a cycle if the ovaries respond poorly. One NHS fertility service describes this as a difficult decision about stopping the treatment cycle when the ovaries respond very poorly or not at all.2 A doctor may also adjust or pause a cycle if there is a safety concern such as a high risk of ovarian hyperstimulation syndrome (OHSS), which affects about 1 to 6% of egg donation cycles.
What are your options if your donor backs out?
Your main options are to rematch with another fresh donor, switch to frozen donor eggs, or wait for the same donor if she can reschedule. Each has different timing and trade-offs.
| Option | How it works | Timing |
|---|---|---|
| Rematch with a new fresh donor | Choose another available donor, who then completes screening and a legal agreement | Several months or longer, depending on screening and scheduling |
| Frozen donor eggs | Choose a cohort of eggs already retrieved, screened and frozen | Eggs can ship to your clinic without waiting for a donor cycle |
| Wait for the same donor | Possible when her situation is temporary and she wants to continue | Uncertain, since it depends on her circumstances |
Frozen donor eggs are often the fastest way to keep a planned timeline. The Donor Nexus Frozen Egg Bank offers cohorts of 6 frozen eggs, shipped worldwide through Cryoport, with an egg survival rate of 90.7% after warming. Our comparison of fresh vs. frozen donor eggs explains how the two paths differ.
“It's not only that you did a great job helping us find a match meeting our unique criteria, but you were able to support us when something went wrong. When our first cycle got cancelled, Miranda quickly provided additional [egg donors] that might work for us, and Lucy worked out an alternative plan with all parties.”

How can intended parents protect themselves?
Intended parents protect themselves by understanding their agreements, choosing a program with clear rematch policies, and keeping a backup plan in mind from the start. A few steps help:
- Read the rematch and refund policy. Ask what happens if a donor withdraws, fails screening or has a cancelled cycle, and what fees are refundable.
- Understand escrow and payment schedules. Donor compensation is typically held in escrow and paid according to the agreement.
- Consider a proven donor. A donor who has completed a cycle before knows what the process asks of her. Our guide to first-time vs. proven egg donors covers the trade-offs.
- Plan a backup. Knowing whether you would rematch or move to frozen eggs makes a hard moment easier. See why having a backup plan matters.
- Ask about guarantees. Some programs offer outcome-based protections, which our article on fertility guarantees explains.
In the Donor Nexus Fresh Matching Program, if a donor does not pass medical screening, intended parents can choose a new donor at no additional agency cost or request a refund minus an administration fee and any fees already paid on the donor's behalf. Since 2012, Donor Nexus has completed more than 1,000 egg retrievals, and about 70% of cycles come from repeat donors and referrals, which gives our team experience helping families through the unexpected.

Frequently asked questions
What happens if an egg donor backs out?
The cycle stops before egg retrieval, and your agency and clinic help you decide on next steps. Most intended parents rematch with another fresh donor, choose frozen donor eggs, or wait if the same donor can reschedule.
Can an egg donor change her mind after signing the contract?
Yes, ASRM guidance says donors may withdraw from the donation process at any point, although once eggs are retrieved the donor no longer controls what happens to them unless the contract says otherwise.
Do intended parents lose money if a donor backs out?
It depends on when she withdraws and what your agreements say. ASRM recommends a written plan for partial donor payment when treatment stops before retrieval, and agencies set their own rematch and refund policies, so review them before you sign.
Are proven egg donors less likely to back out?
A proven donor has already completed at least one cycle, so she knows what the process involves. Life changes can still happen to anyone, which is why a backup plan matters.
Can a cycle be cancelled even if the donor does not back out?
Yes, a doctor may stop a cycle for medical reasons, such as a very low response to stimulation medications or a safety concern, before retrieval takes place.
