What are the main indications for receiving donated oocytes?
Most women receive donated eggs because their ovaries do not produce good quality and/or quantity of oocytes. The main reasons are advanced female age, diminished ovarian reserve, women who are known to be affected by or known to be the carrier of a significant genetic defect or who have a family history of a condition for which carrier status cannot be determined, and women with poor oocyte and/or embryo quality or multiple failures during prior attempts to conceive via assisted reproductive technologies.

- Required age: up to 50 years inclusive.
- An up-to-date clinical, gynecological and infectious evaluation:
- An up-to-date gynecological evaluation that should include: Pap smear, breast examination, transvaginal ultrasonography and a hysterosalpingography.
- HIV (AIDS), hepatitis B and C, RPR (syphilis) (both the recipient woman and her spouse/partner)
- Blood type and Rh factor (both the recipient woman and her spouse/partner)
- Rubella serology (IgG)
- Cervical culture (Chlamydia and Mycoplasm)
- If the patient is more than 40 years old: hemogram, hepatogram, lipidogram, glycemia, EKG (electrocardiogram) and surgical risk, and mammography.
- Psychological evaluation by CEGyR professionals both individually and together with the patient's spouse/partner.
- The male factor is tested with a complete semen analysis.
What are the success rates in egg donation?
The clinical pregnancy rate is about 50%. Twenty five percent are twins and less than 1% are triplets.

In egg donation, does the pregnancy rate decrease in women over the age of 40?
No it does not. Success rate depends on the age of the eggs and not on the age of the uterus. Several studies have showed that rates are stable in recipients between 25 and 50 years old.
What is the top age to be a recipient in CEGyR?
Recipients should not be over 50 years old.
What happens if the donor cycle is cancelled or if no oocytes are retrieved?
At least 4 (four) mature oocytes are guaranteed to each recipient. If donor cycle is cancelled or less than four oocytes are retrieved, the recipient will be matched with another donor. No extras will be charged in these cases.
Is it an anonymous program?
Yes, it is. No identifying information about the donor will be given to the recipient and vice versa.
What is the age of donors?
In our program, they are between 21 and 34 years old. This policy reduces chances of bad quality oocytes and aneuploidies (less chances of miscarriage and chromosomal abnormalities like Down Syndrome).
Why is it a more affordable program than most in the USA and Europe with equally high success rates?
We do split cycles. Sharing the donor oocytes among several recipients reduces costs and shortens the waiting time. As young women donate eggs, most times they are good quality, so that with only 4 (four) mature oocytes the pregnancy rate is good. Besides this, Argentine currency is devalued. This is a high price in terms of local costs but is a low price in comparison to those from the USA and Europe.
How long should a recipient stay in Argentina before coming back home?
We recommend staying for 7 (seven) days. During the staying, the recipient couple will have an appointment with the psychologist, they will have a semen sample frozen and used for fertilization, and they will undergo the embryo transfer.
How many embryos are to be transferred to the recipient?
Two embryos will be transferred to the recipient uterus. The aim is to sustain a good pregnancy rate avoiding having triplets.
What are the obstetric risks in egg donation?
Some papers showed that risks in egg donation are related to the fact that average maternal age is higher than average age in women who get pregnant with their own eggs. This means that risks are not related to the fact that eggs are donated but to the age of recipients. Obstetrics risks in women over 40 years old are hypertension, diabetes, preterm delivery, low-birth weight and second half hemorrhage. These complications are usually well managed in expert prenatal care.
How long will I wait until the transfer is done? How long is the waiting list?
Average time from the day you decide to receive donated eggs to the day the embryos are transferred to your uterus is about 2-3 months.
Is it usual to have foreign recipients in your egg donor program?
More than 10% of all recipients are from abroad. Most of them come from USA and Chile, but it is also common to have recipients coming form Netherlands, Peru, Sweden and Uruguay.
Can we use donated sperm to fertilize donated eggs?
Yes, you can. In Buenos Aires, there are sperm banks were patients can get donated sperm.
