WeFIV, located in the Belgrano neighbourhood of Buenos Aires, Argentina, has been providing expert fertility care since 2006. WeFIV team of specialists with nearly 30 years of experience provides high-quality treatments like egg donation, IVF, and egg freezing.
Equipped with state-of-the-art facilities and a focus on patient comfort, WeFIV completed 1,443 IVF cycles in 2023, with 30% involving egg donation cycles.
WeFIV provides options for you to become a mother, whether you’re starting a single-parent family, are part of a heterosexual couple, or are part of a same-sex couple.
IVF and Egg Donation at WeFIV
WeFIV offers three tailored Egg Donation Programs, guaranteeing 6, 9, or 12 oocytes from a donor, ensuring flexibility to meet diverse patient needs. The clinic prioritizes patient safety and success by adhering to a single embryo transfer (SET) policy, which minimizes the risks of multiple pregnancies while optimizing treatment outcomes.
Healthy Embryo Program
To improve pregnancy success rates and streamline the journey to parenthood, WeFIV provides genetic testing as part of its Healthy Embryo Program. The OVODON NEST Plan combines Egg Donation treatment with PGT-A (Preimplantation Genetic Testing for Aneuploidies) to ensure at least one healthy embryo is available for transfer, increasing the likelihood of a successful pregnancy and a genetically healthy child. Also, whenever possible, specialists at WeFIV practice long culture (till the blastocyst stage) to increase the probability of your success.
Egg Donors at WeFIV
WeFIV’s success is supported not only by advanced technology and a skilled medical team but also by the generosity of egg donors. These donors, provided by WeBank, are healthy women aged 18 to 30 who reside in Buenos Aires, Argentina. Their altruistic contributions make parenthood a reality for many patients.
Convenient Travel Support
To ensure a smooth experience for international patients, WeFIV offers an airport pickup service for $100 and collaborates with local hotels to provide special accommodations near the clinic, making travel and lodging arrangements stress-free.

Clinic has provided the Statement of Truth
We really care about the quality of the information presented on our website.
To make sure that all data provided by clinics is correct - we ask clinics to confirm all data by
"Statement of Truth". The document is signed off by clinic's representatives, scanned and
attached below.
Fresh donor oocytes were used for fertilization with donor or partner's sperm.
Frozen donor eggs Donor oocytes from egg bank were thawed before fertilization with donor or partner's sperm.
Note: As statistics shown in various sources (ESHRE, SART) on average the value of success rate when using frozen eggs may be 10% lower than with fresh eggs.
Embryo transfer day and number of embryos
Embryo transfer day Many clinics prefer to transfer embryos on day 5 at the blastocyst stage as it may lead to better outcomes of an IVF program.
Number of embryos to transfer International and national medical organizations including ASRM, SART and ESHRE discourage the transfer of a large number of embryos because of the increased likelihood of multiple-fetus pregnancies. Multiple-fetus pregnancies, in turn, increase the probability of premature births and related health problems.
Worth to know:
We encourage IVF Clinics to present success rates per cycle rather than per patient. We also ask clinics not to include any frozen embryo transfers in success rates calculation.
Please bear in mind that including frozen embryo transfers (FET) in statistics may increase the overall value of success rates - however at the same time it will increase the cost of the IVF treatment. IVF Clinics usually do not include frozen embryo transfer costs in their programs. That means that if you have any embryos left - the treatment will cost you more than advertised by the clinic.
IVF Success Rates
The way IVF success rates are calculated may vary from clinic to clinic. Calculating and presenting success rates by clinics is a common "communication" issue as clinics try to advertise the best values on their websites.
IVF success rates are usually calculated as a percentage of clinical pregnancies dividing the number of favorable results such as number clinical pregnancies by the number of procedures performed such as a number of embryo transfers, according to the following formula:
"number of pregnancies or number of live births / number of embryo transfers"
You should be aware that the success of IVF treatment is the sum of different factors and circumstances, only few of which depend on the clinic itself. The latter are surely the experience and professionalism of the medical staff as well as offered IVF treatments that allow particular types of patients (with either lower or higher chances of a successful pregnancy).
However, in majority of cases it is your individual situation, condition and medical history that influence the result of the treatment. Your age, genetic factors or various reasons for infertility play a crucial role in determining the IVF success.
Contact in person the clinics you’re interested in and discuss your own perspectives on IVF success instead of studying success rates advertised on clinic's websites.
If you'd like to now more about egg donation success rates please refer to this article:
Here you'll find basic information about the program and the sum of additional costs that are required to carry out the treatment.
The "Additional costs" mean that there are additional costs to cover on top of the advertised program price. You may find these costs in the "Included in program and additional costs" tab below.
Popup - Basic guarantees:
Guarantees refer to number of donor eggs (oocytes) included in the program, number of embryos which are guaranteed on day 3 or day 5 at the blastocyst stage.
Important:
When the clinic offers an embryo guarantee, the basic requirement is good quality partner’s sperm. Usually IVF clinics use WHO standards to assess the sperm parameters. If this is the case, make sure you ask the clinic which particular standards are being applied and what parameters are taken into account. Some fertility clinics apply their own standards. Make sure you ask what happens, if despite good sperm parameters, you will not receive the guaranteed number of embryos.
What does it mean?
Here you will find all the options that are included in the program and those that are necessary to carry out the IVF program but at an additional cost.
All procedures/services which are not included have additional costs that you will have to cover apart from the costs of the Program.
What does it mean?
Other procedures and services that are possible to perform at the Clinic at additional cost.
Remember the decision to use medical services should be made after consulting your doctor.
Refund based on outcome
IVF Refund Program is a term used for financial IVF programs. They give the patient access to two or three IVF cycles for one payment. Usually fresh embryo transfers and extra frozen embryo transfers are included in the price.
A multi-cycle IVF refund program means that the treatment continues until the desired result. It may refer to either clinical pregnancy or a live birth – or until all of the program’s cycles are completed. If the IVF program ends successfully, the clinic will not return your money. However, if you don’t achieve your goal, you can count on a partial or full refund of the costs.
