What is the rate of early pregnancy loss in clinically recognized pregnancies?

The rate of early pregnancy loss in clinically recognized pregnancies is generally understood to be around 10%. This figure accounts for the losses that occur before the end of the first trimester, typically in the first 12 weeks of gestation. Recognized pregnancies refer to those in which a clinical finding or positive pregnancy test confirms the presence of a pregnancy, meaning that the loss occurs after a viable gestation has been established.

It's important to note that rates of early pregnancy loss can be influenced by various factors, including maternal age, underlying health conditions, and chromosomal abnormalities in the embryo, but on a broad population level, the 10% figure serves as a widely accepted estimate. This knowledge helps in counseling patients regarding the likelihood of loss, allowing them to better understand the risks associated with early pregnancy.

Other figures, such as 5%, 25%, and 50%, do not accurately represent the typical statistics for early pregnancy loss in recognized pregnancies and could convey misleading information about the commonality and expectations surrounding early pregnancy and its risks.
