The rate expressed as the number of clinical pregnancies per 100 initiated cycles is known as what?

• A. Clinical fertility
• B. Corona Radiata cells
• C. Cryopreservation
• D. Clinical pregnancy rate

Answer: (D)

In fertility statistics, the clinical pregnancy rate is the measure that expresses how often a cycle started results in a clinically confirmed pregnancy, per 100 initiated cycles. A clinical pregnancy is confirmed by ultrasound evidence such as a gestational sac or fetal heartbeat, not just a positive pregnancy test. This metric helps gauge success on a per-cycle basis in ART, distinguishing it from other rates like per embryo transfer or live birth. The other terms don’t describe this per-initiated-cycle pregnancy rate: clinical fertility isn’t a standard metric, Corona Radiata cells refer to the surrounding ovarian cells, and cryopreservation is the process of freezing embryos or gametes.
