Clinical Pregnancy Rate

Meaning

The Clinical Pregnancy Rate is a definitive metric in reproductive endocrinology and assisted reproductive technology (ART), representing the percentage of initiated treatment cycles or embryo transfers that result in a pregnancy confirmed by objective clinical evidence. This evidence typically involves the visualization of at least one gestational sac, and often a fetal heartbeat, via ultrasound examination, usually performed five to six weeks after embryo transfer. It serves as a reliable, standardized measure of success that distinguishes viable pregnancies from early biochemical losses.
