When you've decided to use donor eggs for IVF, the next decision is whether to use fresh or frozen (vitrified) eggs. Both are clinically proven pathways with good success rates, but they differ in important ways — timing, cost, how many eggs you get, and how much control you have over the process. Understanding the trade-offs helps you choose the approach that best fits your situation and priorities.
How Each Works
Fresh donor-egg cycle: A donor is selected and matched to you. She undergoes ovarian stimulation (just like a standard IVF cycle), and her eggs are retrieved. Those eggs are fertilized with your partner's (or donor) sperm on the day of retrieval, cultured to blastocyst, and either transferred fresh or frozen for later use. Your cycle is synchronized with the donor's — you prepare your endometrium with estrogen and progesterone while she's being stimulated, so your uterus is ready for transfer when her eggs are fertilized and cultured.
Frozen donor-egg bank: Eggs have already been retrieved from donors, vitrified (flash-frozen), and stored in an egg bank. You select from available inventory — choosing based on donor profiles and the number of eggs in a cohort. When you're ready, the eggs are shipped to your clinic, thawed, fertilized via ICSI, and cultured for transfer. No synchronization with a donor is needed — you control the timing entirely.
Success Rates
With modern vitrification technology, frozen donor-egg success rates have approached — though not quite matched — fresh donor-egg rates:
| Metric | Fresh Donor Eggs | Frozen Donor Eggs |
|---|---|---|
| Eggs available per cycle | 10–20+ (full retrieval) | 6–8 (typical bank cohort) |
| Egg survival after thaw | N/A (never frozen) | 85–95% |
| Fertilization rate | 70–80% | 65–75% |
| Clinical pregnancy rate per transfer | 55–65% | 45–55% |
| Cumulative live birth rate (all embryos) | Higher (more eggs = more embryos) | Lower per cohort (fewer starting eggs) |
The per-transfer pregnancy rate difference has narrowed significantly as vitrification technology has improved. The bigger practical difference is in the number of eggs — a fresh cycle gives you the donor's full retrieval (often 10–20+ eggs), while a bank cohort typically provides 6–8 eggs. More eggs means more embryos, more chances for PGT-A testing, and potentially more frozen embryos for future siblings.
Advantages of Each
Fresh advantages: More eggs per cycle (higher cumulative pregnancy rates and sibling potential), the ability to choose your donor specifically and ask detailed questions, PGT-A testing of all resulting embryos, no egg-thaw attrition, and a slightly higher per-transfer pregnancy rate.
Frozen advantages: No waiting for donor matching and synchronization (you choose from available inventory), lower cost (no donor stimulation medications or compensation), schedule flexibility (you set the timeline), no risk of donor-cycle cancellation, and faster treatment start — you can proceed in weeks rather than months.
Cost Comparison
| Component | Fresh (Colombia, typical 2026) | Frozen Bank (Colombia, typical 2026) |
|---|---|---|
| Donor compensation | $1,500–$2,500 | Included in cohort price |
| Donor medications | $1,500–$2,500 | Included |
| Egg cohort (frozen) | N/A | $3,000–$5,000 (6–8 eggs) |
| Recipient IVF cycle | $3,500–$5,000 | $3,500–$5,000 |
| ICSI + culture | Often included | Often included |
| Total estimate | $6,500–$9,500 | $5,500–$8,000 |
Fresh cycles cost more but deliver more eggs and embryos per dollar spent. Frozen cohorts cost less per cycle but may produce fewer embryos, potentially requiring a second purchase for additional attempts.
Which Is Right for You?
Fresh is typically better if: you want maximum eggs and embryo potential, you plan to do PGT-A on all embryos, you want the option of future siblings from the same donor, you're flexible on timing and can accommodate the donor's stimulation schedule, and budget accommodates the higher upfront cost.
Frozen is typically better if: you want to start quickly without waiting for donor matching, you're budget-constrained and want a lower entry point, you're flexible about the number of embryos (you're focused on one child), you want full control over your treatment timeline, or you're considering a trial cycle before committing to a fresh donor's full cohort.
Donor Eggs in Colombia
Colombian fertility clinics offer both fresh and frozen donor-egg programs. Fresh donor cycles benefit from Colombia's robust donor recruitment — young, diverse donors with Latin American phenotypes, often matched within 2–4 weeks. Some clinics also maintain in-house frozen egg banks, and international frozen egg banks can ship to Colombian clinics.
The total cost advantage of either pathway in Colombia is substantial compared to the US, where fresh donor-egg cycles typically run $25,000–$40,000 and frozen cohorts $15,000–$22,000. Colombia's pricing makes it feasible to pursue multiple attempts or to start with a frozen cohort as a trial before committing to a full fresh cycle.
