How to Interpret IVF Success Rates
Success rates are typically reported as clinical pregnancy rate per embryo transfer. When comparing clinics, ensure you're comparing the same metrics. The ICMR (Indian Council of Medical Research) mandates clinics to maintain treatment outcome records, but public reporting is still evolving.
- Ask for live birth rate, not just pregnancy rate
- Request age-specific success rates, not overall averages
- Check if the rate includes all cycles started or only embryo transfers
- Compare rates from the same year — success rates improve as technology advances
