Egg Donation

Egg donation is indicated for patients with diminished ovarian reserve, premature ovarian insufficiency, or poor ovarian response in previous IVF cycles. It’s also the appropriate path after multiple failed IVF attempts with own eggs, for patients of advanced maternal age (typically over 40–42), or when known genetic conditions make using one’s own eggs inadvisable.

Unlike the one-donor-to-one-recipient model common in the United States, CEGYR operates a shared donor program: multiple recipients benefit from a single donor’s egg cohort. This approach reduces costs and wait times while maintaining high success rates — because donor cycles at CEGYR typically yield enough mature eggs for several recipients.

All donors are between 21–32 years old and undergo comprehensive screening including genetic assessment, infectious disease testing, psychological evaluation, and a full reproductive workup before any donation cycle.

• Minimum 8 or 10 mature eggs per recipient (depending on whether you decide to do PGT-A)
• Blastocyst (day 5–6) transfer — the stage associated with the highest implantation rates
• Approximately 85% of patients have multiple blastocysts available for future frozen transfers
• ISO 9001 certified laboratory
• Recipients up to age 53 are evaluated individually on a case-by-case basis

Most international patients complete the entire process in a single short trip to Buenos Aires — just 1–2 days, for the embryo transfer itself.

The initial consultation is by video call. Once you decide to proceed, egg retrieval from the donor, fertilization, blastocyst development, and PGT-A (if selected) all happen while you remain at home. Our team keeps you informed throughout.

Once viable embryos are confirmed, we coordinate your travel. Endometrial preparation is managed locally with your own doctor, following our precise protocol. You travel to Buenos Aires only for the transfer — and return home the following day.

Any remaining blastocysts are vitrified and stored at CEGYR for future frozen embryo transfer cycles, which can be coordinated remotely.
