Our clinical pregnancy rate is over 50% in women below the age of 40. It drops
substantially in women above that age.
See Success Rates >> >>
Miscarriage and chromosomal anomalies increase as female age increases. In the case of oocyte donation, miscarriage and chromosomal anomalies are not affected by the recipient's age.
We recommend staying for two weeks.
Yes. Utilizing a novel laboratory technique called CGH (arrays-Comparative Genomic Hybridization) we can evaluate embryos for chromosomal abnormalities before transfer.
Most women receive donor eggs because their ovaries do not produce good quality and/or quantity of oocytes. The main reasons for this are advanced female age, diminished ovarian reserve, women who are known to be affected by or known to be carriers 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 to conceive via assisted reproductive techniques.
The clinical pregnancy rate is around 50%. Twenty five percent of these pregnancies are twin pregnancies and less than 1% are triplets.
No, it does not. Success rate depends on the age of the eggs and not on the age of the uterus. Several studies have shown that rates remain stable in recipients between 25 and 50 years old.
Recipients should not be over 50 years old.
At least 6 (six) mature oocytes are guaranteed to each recipient. If the 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.
Yes, the program is anonymous to both the recipient and the donor. No identifying information will be provided.
In our program, the donors are 21 to 30 years old. This reduces the chances of poor quality oocytes and aneuploidies (chromosomal anomalies): less chances of Down’s syndrome.
We perform split cycles. That means that donor eggs are shared among the recipients (usually two). This reduces costs and shortens the waiting time. Since our donors are young they usually provide good quality eggs; using 6 (six) mature oocytes we achieve an excellent pregnancy rate. Argentine currency is devaluated, what makes it even cheaper for foreign patients coming from the US and Europe.
Usually 7 to 10 days. During that time the recipient and her partner will be seen in consultation (first visit), a sperm sample will be obtained and frozen for later use at the time of egg retrieval, and she will undergo embryo transfer.
Two embryos will be transferred to the recipient’s uterus. The aim is to have a good chance of getting pregnant, avoiding the risk of triplets.
The obstetric risks in egg donation are related to the age of the recipient. Obstetrics risks in women over the age of forty are: hypertension, diabetes, preterm delivery, low-birth weight and second half bleeding. These complications are usually well managed with expert prenatal care.
Usually, not more than a week. The waiting time for donor assignment is around two to three months from the moment you decide to join our program.
Yes. Our sperm bank has a wide selection of European-type donors.
In patients with obstructive azoospermia, such as those men previously vasectomized or men born with congenital absence of the deferens vas (CABVD), the retrieval rate is usually 100%. Only exceptionally are we not able to retrieve sperm from these men. In patients with non-obstructive azoospermia the retrieval rate is slightly over 50%.
Yes. Our sperm bank is nationally recognized and has provided donor sperm for local physicians for over twenty-five years.
Our donors are recruited from local universities and have a European background. We do not carry ethnic donors since our population is, mainly, of European extraction. Our sperm donors undergo testing like egg donors, in order to avoid the chances of infection and in order to minimize the risk of transmitting genetic diseases to the resultant offspring.
Yes, our program is anonymous. Particular traits of the donor can be provided but no identifying information will be available. Likewise, the donor will never know whom his sperm went to.
Although we have no current legislation regarding this subject, we believe donors should remain anonymous and this is consistent with our idiosyncracy as well as in other countries in South America.
Dr. Osés is a highly trained US physician and has great experience dealing with patients with difficult fertility problems, often involving third party reproduction treatment. His Gynecological and Fertility Institute is one of the largest in the country, performing over 1,000 cycles of ART every year. He also runs the oldest and best known sperm bank in the country. He was the first physician seriously involved in donor treatments and has set the standards for donor management in the country. He has practiced in the States and his associate is also bilingual; there is obviously no need for translators. Argentina’s currency is devaluated and the exchange rate is favorable to tourists. Our donors are mostly European (background) and have no interest (they are reimbursed for their willingness to participate) other than helping others achieve their dream. No legal problems have ever occurred in this country regarding the status of the donors or patients receiving treatment with donor gametes.
