IVF Success Rate Predictor
Estimate your probability of a live birth per embryo transfer based on clinical data.
How IVF Success Rates are Calculated
The success of In Vitro Fertilization (IVF) is not a single number. It is a complex probability influenced by biological, clinical, and lifestyle variables. Our IVF success rate calculator uses weighted statistical modeling based on thousands of reported cycles to provide a realistic expectation for your journey.
Key Factors Influencing Your Results
1. Maternal Age and Egg Quality
Age remains the most significant predictor of success when using own eggs. As women age, both the quantity and the chromosomal quality (euploidy) of eggs decrease. For women over 40, the use of PGT-A (Preimplantation Genetic Testing for Aneuploidies) or donor eggs often becomes a primary recommendation to improve success rates.
2. Egg Source: Own vs. Donor
When using donor eggs, the age of the recipient does not significantly impact the success rate. Donor eggs typically come from young, healthy donors (usually aged 21-30), which resets the success probability to a much higher baseline, often exceeding 50% regardless of the mother's age.
| Age Group | Average Live Birth Rate (Own Eggs) |
|---|---|
| Under 35 | 51.0% – 54.5% |
| 35 – 37 | 38.3% – 42.0% |
| 38 – 40 | 25.1% – 30.5% |
| 41 – 42 | 12.7% – 15.0% |
| Over 42 | 3.5% – 5.0% |
Understanding the Diagnosis Impact
Certain diagnoses, such as PCOS, often result in a higher number of eggs retrieved, which can lead to more chances for a successful transfer. Conversely, Endometriosis or Diminished Ovarian Reserve may require customized stimulation protocols to achieve optimal results. Male factor infertility is often effectively mitigated through ICSI (Intracytoplasmic Sperm Injection).
Steps to Improve Your Chances
- Lifestyle Adjustments: Maintaining a healthy BMI, quitting smoking, and reducing alcohol intake are shown to improve cycle outcomes.
- Supplementation: Many specialists recommend CoQ10, Folic Acid, and Vitamin D to support egg and sperm health.
- Clinic Selection: Review SART data for specific clinics to ensure they have high success rates for your specific age bracket.
