HRC success rates and data

HRC’s success-rate page links to sources such as SART and notes that patient characteristics and treatments affect comparisons. Confirm the institution, report year, and treatment type rather than using one overall figure for every site or service.

Clinical pregnancy, live birth, rates per transfer, rates per cycle, and cumulative results are different measures. Denominators and observation periods can substantially change numbers. Identify which people and stages are counted.

Age, gamete source, treatment type, history, and patient selection can affect reports. Do not directly apply another group’s results to yourself or simply rank figures with different years or definitions.

A medical cycle outcome and completion of a surrogacy project cover different things. Matching, agreements, pregnancy, delivery, and subsequent procedures cannot be summarized by one medical success rate.

HRC can explain the relevance to your circumstances. Record the institution, year, treatment population, and outcome definition before discussing what it tells you.

• Which clinic and year?
• Per transfer or cycle, and pregnancy or live birth?
• A comparable patient group?
• Can it inform my situation and what are the limitations?

Published statistics cannot be directly converted into an individual result. Doctors assess personal outcomes and risks.
