Clinical pregnancy rate
The proportion of treatment cycles or transfers that result in a pregnancy confirmed by ultrasound, typically showing a gestational sac or heartbeat.
In plain English
It's the percentage of cycles where a scan actually shows a pregnancy, not just a positive blood test.
Why it matters
It's a more meaningful figure than a positive test alone when comparing clinic success rates, though live birth rate matters more.
