IVF Success Rate Calculator

Estimate your IVF success probability based on key factors

Important Medical Disclaimer

This calculator provides estimates based on population averages from CDC and SART data. Your actual success rate depends on many individual factors including egg quality, sperm quality, uterine environment, and clinic-specific success rates. These estimates should NOT be used as medical advice. Consult your reproductive endocrinologist for personalized success rate estimates based on your complete medical history.

• Clinic and laboratory quality

Frequently Asked Questions About IVF Success Rates

How accurate are IVF success rate calculators?

IVF success rate calculators provide estimates based on CDC and SART data from thousands of cycles. While they offer useful predictions based on key factors like age and diagnosis, individual results can vary significantly. For the most accurate prediction, consult your fertility clinic which can provide success rates based on their specific laboratory and your complete medical profile.

What AMH level is good for IVF success?

AMH levels between 1.0-4.0 ng/mL are generally considered good for IVF success, indicating adequate ovarian reserve. AMH above 4.0 suggests high reserve but may increase OHSS risk, while levels below 1.0 indicate diminished reserve and typically lower egg retrieval numbers. However, egg quality matters more than quantity, and IVF can succeed even with low AMH levels.

How does age affect IVF success rates?

Age is the single most important factor in IVF success. Women under 35 have 40-55% success rates per transfer, while those 35-37 see 33-40%, ages 38-40 have 23-27%, ages 41-42 see 12-15%, and over 42 have 3-7% success rates. This decline reflects decreasing egg quality and quantity with age, making early intervention important for fertility preservation.

Does PGT testing improve IVF success rates?

PGT-A genetic testing improves IVF success rates by identifying chromosomally normal embryos before transfer. For women over 37, PGT can increase success rates by 40% or more per embryo transferred. While PGT adds cost and may reduce the number of available embryos, it significantly improves implantation rates and reduces miscarriage risk by ensuring only healthy embryos are selected.

What is a good IVF success rate?

A good IVF success rate depends heavily on age. For women under 35, success rates of 40-55% per transfer are considered good, while 30-40% is good for ages 35-37, and 20-30% for ages 38-40. Clinic success rates above these benchmarks indicate strong laboratory practices and protocols. Remember that cumulative success rates over multiple cycles are often more relevant than single-cycle statistics.

How do I calculate my IVF success rate?

To calculate your IVF success rate, enter your age, diagnosis, AMH level, and other factors into an IVF calculator. The tool analyzes these variables against CDC and SART data to estimate your probability of live birth per embryo transfer. For personalized calculations, your fertility clinic can provide success rates specific to their laboratory and your complete medical history.

Is frozen embryo transfer more successful than fresh?

Frozen embryo transfers (FET) often have slightly higher success rates than fresh transfers, typically 5-10% better. This advantage comes from allowing the body to recover from stimulation medications and achieving optimal uterine lining conditions. FET also enables PGT testing and better timing, though fresh transfers remain successful and may be preferred in certain circumstances.

What factors affect IVF success rates the most?

The factors affecting IVF success rates most significantly are maternal age (most important), ovarian reserve (AMH and AFC), embryo quality, uterine receptivity, male factor issues, and lifestyle factors like BMI and smoking. Clinic-specific factors including laboratory quality, protocols, and embryologist expertise also play crucial roles. Combining multiple positive factors significantly improves overall success probability.
