Cyprus IVF Success Rates
We transparently review cumulative positive pregnancy and live birth outcomes from Ventus IVF clinical records by treatment, age and treatment journey.

Cumulative assessment differs from the first transfer. Positive pregnancy and live birth are also separate clinical outcomes. The groups on this page should be read using the same metric definitions.
By treatment type
Cumulative Success Outcomes by Treatment
We present IVF, egg donation, sperm donation and embryo donation outcomes separately, using positive pregnancy and live birth metrics.
Egg Donation

First attempt ≠ entire treatment journey
First Attempt and Cumulative Outcome
The difference between the first transfer result and cumulative success shows why a treatment journey should not be evaluated from a single attempt.

Special success data
Oocyte and Embryo Donation Age 45+
In this special group, we show first-attempt, cumulative positive pregnancy and cumulative live birth outcomes separately.
● Average female age: 48
72.5%Positive pregnancy on first attempt
84.5%Cumulative positive pregnancy
64%Cumulative live birth
These values are recorded clinical outcomes for a defined oocyte and embryo donation patient group; they do not represent an individual probability of success for every 48-year-old patient.
A system that does not leave success to chance
Science, Technology and a Controlled Laboratory Process
We do not present success as the result of a single device. Clinical planning, embryology expertise, laboratory standardisation and technology-assisted assessment work together.
AI-Assisted Assessment
Provides the specialist team with additional data and decision support in egg, sperm and embryo assessment.
View details →Continuous Monitoring with EmbryoScope+
Embryo development can be monitored through time-lapse imaging while maintaining incubator conditions.
View details →VOC-Controlled Laboratory
Control of volatile organic compounds and environmental variables is part of laboratory standardisation.
View details →CAP-Accredited Laboratory
Quality, traceability, staff competence and laboratory processes are managed according to defined standards.
View details →Chip ID and Identity Security
Adds an identity verification and traceability layer to gamete and embryo processes.
View details →Vitrification
A rapid cryopreservation approach is used in embryo and oocyte freezing and storage processes.

Data methodology
How should you read success rates?
As well as the percentage itself, it is important to understand which outcome and time period it represents.
01Real records
Clinical outcomes found in patient records are used.
02Outcome definition
Positive pregnancy and live birth are separate metrics.
03Cumulative scope
The overall defined treatment journey is considered rather than only the first transfer.
04Personal interpretation
A clinical average is not a guarantee of individual success.
Cyprus IVF success rates
We do not explain success with a single percentage
When evaluating Cyprus IVF success rates, looking only at the highest number is not enough. Treatment type, female age, gamete source, first-transfer outcome and cumulative live birth are different parts of the same clinical picture.
For this reason, in the Ventus IVF success data centre we present IVF, egg donation, sperm donation and embryo donation outcomes separately, while IVF and donor groups are compared according to the way they are structured in our records.
What is behind success?
Personalised treatment planning, embryology expertise, a controlled laboratory environment, AI-assisted assessment, EmbryoScope+ monitoring, VOC control, the CAP quality framework, Chip ID and vitrification form a complementary system.
Frequently asked questions
Questions about success rates
Cumulative success looks beyond the result of the first embryo transfer and considers the combined outcome of transfers within the defined treatment journey. In this dataset, cumulative positive pregnancy is assessed after a maximum of 3 embryo transfers.
No. Positive pregnancy records a pregnancy as positive after transfer, while live birth records a pregnancy that results in a live birth. They are therefore presented together, but as separate clinical outcomes.
There are different biological and clinical stages between a positive pregnancy and live birth. Early pregnancy loss, chromosomal and embryological factors, maternal age and other medical factors during pregnancy can result in a lower live birth rate.
The main clinical rates shown on these pages are derived from treatment outcomes in Ventus IVF patient records. Positive pregnancy, live birth, first transfer and cumulative outcome are defined separately; the public presentation shows percentages rather than patient or ET counts.
In the source dataset, embryo transfer outcomes for the relevant treatment group are followed and the cumulative outcome is assessed after a maximum of 3 ETs. The first-transfer rate and cumulative rate are therefore not the same.
When a sample in an age group is small, all observed outcomes may be positive, producing a raw rate of 100%. This does not mean every new patient in that age group has a 100% chance of success.
To reduce small-sample effects within age bands, the observed age-group rate is drawn toward the overall cumulative rate of the relevant group according to sample size. The balancing formula used for the web presentation is (n × raw rate + 20 × overall group rate) / (n + 20). The main cumulative group rates are not altered by this process.
No. Clinical rates summarise the historical outcomes of a patient group. Age, ovarian reserve, oocyte and sperm source, embryo development, genetics and clinical history can affect an individual's outcome.
No. These systems support assessment, monitoring, environmental control, quality and traceability. No technology on its own guarantees a particular pregnancy or live birth outcome.
