Fresh vs. Frozen Donor Eggs in Mexico

At Instituto Mexicano de Infertilidad (IMI), we believe informed choices lead to the best outcomes. When it comes to egg donation in Mexico, one of the most common questions patients ask is whether to use fresh donor eggs or frozen donor eggs.

Both approaches can lead to healthy pregnancies and beautiful families—but each has unique benefits, timelines, and costs. This guide compares both options so you can make a confident decision based on your personal, medical, and emotional needs.

Which Option Is Right for Your IVF Journey?

Fresh Donor Eggs

Fresh donor eggs come from a synchronized cycle between the donor and the intended recipient. The donor undergoes stimulation, her eggs are retrieved, and they are immediately fertilized with the partner’s or donor’s sperm to create embryos. What are the advantages of fresh eggs?

Higher number of eggs retrieved (10–20 per donor).
Greater total embryos for future use.
Option to perform advanced genetic testing (PGT-A) on embryos.
Feels more “organic” for patients who want live, synchronized creation.

Frozen Donor Eggs

Frozen donor eggs are retrieved, vitrified (flash-frozen), and stored for future use. When you’re ready, the eggs are thawed, fertilized, and transferred in your own cycle—no synchronization with the donor is required.

At IMI, both options are available, and our fertility specialists will guide you in choosing the right one for your situation. What are the advantages of frozen eggs?

Immediate availability—no need to wait for donor synchronization.
Lower total cost (up to 30 % savings).
Ideal for international patients with limited travel time.
Reduced scheduling complexity and medication load.

The Fresh Donor Egg Process

Donor Matching & Screening

Choose your donor from IMI’s database of pre-screened, healthy candidates.

Cycle Synchronization

Hormonal therapy aligns your uterine cycle with the donor’s egg retrieval schedule.

Egg Retrieval & Fertilization

Eggs are collected and fertilized with your partner’s or donor’s sperm the same day.

Embryo Transfer

A high-quality embryo is transferred into your uterus after 3–5 days of development.

The Frozen Donor Egg Process

Select Eggs from IMI’s Cryobank

Choose from a wide inventory of frozen eggs available immediately.

Endometrial Preparation

Your uterus is prepared for transfer with estrogen and progesterone.

Egg Thawing & Fertilization

Our embryologists carefully thaw eggs and fertilize them using ICSI or PICSI.

Embryo Transfer

Healthy embryos are transferred or frozen for future cycles.

Cost Comparison

Item	Fresh Donor Eggs	Frozen Donor Eggs
Donor Compensation	Included	Included
Synchronization Medications	Required	Not Required
Egg Retrieval	Yes	Already Completed
Average Cost (USD)	$8 000 – $10 000	$6 000 – $8 000
Travel Time	10–14 days	7–10 days

Both are substantially more affordable than donor-egg IVF in the U.S., where costs range from $25 000 – $35 000 per cycle.

Success Rates: Fresh vs Frozen

Both methods deliver excellent results at IMI, but subtle differences exist:

Method	Success Rate per Transfer	Typical Use Case
Fresh Donor Eggs	75–80 %	For patients seeking maximum embryo yield and real-time fertilization
Frozen Donor Eggs	65–75 %	For patients prioritizing convenience, travel flexibility, and lower cost

Our advanced vitrification and thawing techniques maintain >95 % egg survival, ensuring frozen eggs remain a strong option for most patients.

International Patients

For international patients, convenience is key. That’s why many traveling from the U.S. and Canada choose frozen donor eggs, which require shorter stays in Mexico.

However, patients seeking to create multiple embryos or use partner sperm in real time often prefer fresh donor eggs for the best yield.

IMI provides complete travel coordination, including airport pickup, hotel arrangements, and bilingual support throughout your stay in Guadalajara.

Q1. Are fresh donor eggs better than frozen?

Fresh eggs typically yield more embryos and slightly higher success rates, but frozen eggs offer faster, more flexible scheduling.

Q2. How many frozen eggs are included in a package?

IMI frozen donor egg sets typically include 6–8 mature eggs per batch.

Q3. Can I choose the same donor for future siblings?

With fresh cycles, yes. With frozen eggs, it depends on donor availability at the time.

Q4. Are frozen eggs as healthy as fresh eggs?

Yes. Thanks to vitrification, frozen eggs maintain excellent survival and fertilization rates (>95 %).

Q5. How long do I need to stay in Mexico for each option?

Fresh cycles require about 10–14 days; frozen cycles can be completed in 7–10 days.
