Cyprus in vitro fertilization success rates are one of the most frequently compared but easily misinterpreted information when choosing a center. Seeing a remarkable rate like 80 percent or 90 percent on a website doesn’t mean you have the same probability. Because success; It varies depending on the type of result measured, the age distribution of the patients, the egg source and from which treatment phase the calculation starts.
For a realistic evaluation, your own age, diagnosis, previous attempts and planned treatment type should be taken into account rather than a single overall percentage. This article helps you read the rates shared by clinics correctly and ask more useful questions during the first meeting. The aim is not to give hope with a low or high number, but to support your decision with properly defined data.
What does success mean in in vitro fertilization?
Positive pregnancy test
The increase in beta hCG hormone in the blood after embryo transfer is called biochemical pregnancy. This early result is a positive sign; However, not every positive test progresses to a gestational sac or live birth on ultrasound. A center that only shares its positive test rate may show a higher percentage.
clinical pregnancy
Observation of the gestational sac in the uterus and heartbeat at the appropriate time on ultrasound are among the clinical pregnancy criteria. Clinical pregnancy is a more advanced outcome than a positive test; However, the possibility of pregnancy loss is not completely eliminated.
live birth
The most meaningful outcome for the patient is often a live birth. However, collecting live birth data requires longer follow-up. It should be clarified whether the rates published by the centers for the same year track patients whose treatment started, those who were transferred, or only pregnancies.
On which denominator is the ratio calculated?
A center can calculate success per embryo transfer. The rate appears higher when patients whose embryos were not formed despite egg collection or whose transfer was canceled are not included in this calculation. The calculation per cycle started includes everyone who starts treatment and gives a different result.
Cumulative success per patient can capture the results of all fresh and frozen embryos from an egg retrieval over a period of time. This approach is more comprehensive than a single transfer rate. When comparing, make sure that two centers use the same definition.
How does age affect in vitro fertilization success?
A woman’s age is one of the most important variables in IVF with her own eggs. As age progresses, the number of eggs and the possibility of obtaining chromosomally healthy embryos may decrease. Egg quality and embryo development of two women of different ages with the same AMH value may not be the same. AMH gives more information about egg reserve; It does not alone indicate egg quality or pregnancy outcome.
Young age is no guarantee of success either. Tubal problems, endometriosis, intrauterine problems, sperm factor or unexplained infertility may affect the result. When age groups are kept wide, the probability of a 35-year-old patient and a 39-year-old patient can be shown in the same table. Therefore, ask for data from as narrow an age range as possible.
Why should own egg and donor egg rates be separated?
In donor egg programs, the egg comes from a young and health-screened donor. Therefore, the possibility of obtaining an embryo may be higher compared to treatment with the older recipient’s own egg. If clinics’ overall success percentage includes donation patients, the result may overestimate standard IVF success.
Even when donor eggs are used, sperm quality, laboratory conditions, uterine lining and transfer technique remain important. In addition, the age of the woman carrying the pregnancy should be evaluated in terms of blood pressure, diabetes and pregnancy complications. A single ratio not broken down by egg source is not sufficient for personal decision-making.
How can sperm factor affect success?
Sperm count, motility and morphology can influence the choice of fertilization method. Since a single sperm is injected into the egg with ICSI, fertilization can be achieved in many cases where there are low sperm numbers. However, sperm DNA integrity, serious morphology problems, or surgically obtained sperm may be related to embryo development.
A single spermiogram result may not be sufficient to make a definitive decision. Febrile illness, sample collection conditions, abstinence period and laboratory differences may change the results. When deemed necessary, the test is repeated and a urology evaluation is performed.
Embryo and laboratory factors
The maturity of the eggs, the fertilization rate and the developmental pattern of the embryos are as important as the number of eggs collected. Not every fertilized egg reaches the blastocyst stage. The laboratory’s incubator conditions, air quality, culture procedures, embryologist experience, and sample safety play a role in the outcome.
The mere appearance of embryos does not indicate definitive genetic health. Time-lapse viewing and AI-powered scores can support selection; but it does not guarantee pregnancy. The risks of multiple pregnancy should also be taken into account when determining the number of embryos to be transferred.
Uterus and transfer factors
It is important for the endometrium to have a suitable appearance at the time of transfer, to evaluate intrauterine polyps or significant myomas, and to manage conditions such as hydrosalpinx. It is not correct to think that every unsuccessful transfer originates from the uterus; However, depending on the medical history, intrauterine examination may be required.
During embryo transfer, the thin catheter must be placed into the uterus to reduce trauma and the timing must be done correctly. Lying down for a long time or stopping daily life completely after the transfer does not guarantee success. It is more important to use medications as recommended and comply with the test day.
What to examine when the first attempt fails?
Failure to become pregnant on the first try is a common occurrence and does not in itself indicate a serious problem. The number of mature eggs collected, fertilization, embryo development, transfer day, endometrium and medication protocol used are reviewed together. The previous cycle provides valuable biological information for the next plan.
It is not necessary to perform numerous additional tests or evidence-limited practice after each unsuccessful attempt. Ask what findings the additional review is based on, how it would change the outcome, and how much it costs. If there are frozen embryos, a subsequent transfer to a new egg collection site can be planned.
Information you need to know your own likelihood of success
- Woman’s age, AMH value and number of antral follicles
- Menstrual and pregnancy history
- Findings regarding the uterus and tubes
- Spermiogram and urology evaluation, if any
- Drug dose used in previous treatments
- Number of mature eggs, fertilization and blastocysts collected
- Previous transfer and pregnancy outcomes
- Chronic diseases, weight and lifestyle factors
Considering this information together is more useful than an overall web percentage. Calculation tools can provide an initial estimate; The final treatment decision should be made with a doctor’s consultation and current examinations.
What questions should you ask the center?
Ask whether the shared rate is a live birth or a clinical pregnancy, which year’s data it is from, and how many patients it is calculated on. Find out if own egg, donor egg and frozen transfer results are available separately. It is also important whether patients whose transfers were canceled are included in the account.
At Vita Altera IVF Center, your file can be evaluated together with age, egg reserve, sperm findings and previous embryology reports. In the online preliminary meeting, instead of giving you a definite pregnancy promise, the strong and weak factors affecting the possibility, appropriate treatment options and realistic expectations are explained.
What data is needed to predict personal success?
Age, egg source, AMH, antral follicle count, previous treatment response, sperm findings, uterine condition and the number of embryos formed should be evaluated together. A single clinic-wide success rate does not reflect these variables. Therefore, attend the interview with as complete a medical record as possible.
Ask the center if the estimate is per transfer, per egg retrieval, or per initiating patient. Positive test, clinical pregnancy, and live birth are different outcome measures. Clear definitions help you compare data from two clinics more fairly.
What does the success rate in in vitro fertilization mean?
Depending on the definition the center uses, a positive blood test may indicate clinical pregnancy, ongoing pregnancy, or a live birth rate. When evaluating the percentage, be sure to ask which result it is.
Is success possible in the first in vitro fertilization attempt?
Yes, it is possible; However, it depends on age, egg and sperm quality, diagnosis, embryo development and uterine factors. Failure to achieve pregnancy in the first attempt does not mean that subsequent attempts will fail.
Do donor eggs increase the success rate?
In some patients with advanced age or poor egg quality, obtaining an embryo with a young donor egg may increase the possibility. Uterine health, sperm and laboratory factors also affect the result.
Is a 90 percent guarantee of success realistic?
The guarantee of pregnancy or live birth is not realistic for every patient. It should be questioned whether the very high percentages are based on patient selection, donation program, or a different outcome measure such as a positive test.
