**Question:** Definition of recurrent pregnancy loss classically is

A. Pregnancy loss thrice or more
B. Pregnancy loss more than twice
C. Pregnancy loss twice or more
D. Pregnancy loss once or twice

**Correct Answer:** B. Pregnancy loss more than twice

**Core Concept:** Recurrent pregnancy loss (RPL) refers to a condition characterized by the loss of two or more consecutive pregnancies before the fetus reaches 20 weeks of gestation or is born alive. This definition is commonly used to differentiate RPL from spontaneous miscarriages, which are typically single occurrences.

**Why the Correct Answer is Right:** The correct answer is B, "Pregnancy loss more than twice." This is because the definition of RPL focuses on the frequency of pregnancy losses, specifically mentioning that it involves two or more consecutive pregnancies. The other options are incorrect for the following reasons:

A. Pregnancy loss thrice or more: This option is too broad, as a single pregnancy loss can be considered RPL if it occurs consecutively.
C. Pregnancy loss twice or more: This option is too narrow as it only accounts for two consecutive losses, which may not accurately represent RPL cases.
D. Pregnancy loss once or twice: This option is too specific, as it only considers single or double losses, which do not meet the criteria for RPL.

**Why Each Wrong Option is Incorrect:**

A. Pregnancy loss thrice or more: This option is too broad as a single pregnancy loss can be considered RPL if it occurs consecutively. For example, a woman experiencing a single loss is not considered to have RPL unless she has subsequent losses.
C. Pregnancy loss twice or more: This option is too narrow as it only accounts for two consecutive losses, which may not accurately represent RPL cases. Some women might experience three or more consecutive losses, but not yet reach the classification of RPL.
D. Pregnancy loss once or twice: This option is too specific, as it only considers single or double losses, which do not meet the criteria for RPL.

**Clinical Pearl:** Recurrent pregnancy loss is a complex issue that often requires thorough investigation to determine potential causes and manage them appropriately. These causes can include immunological, endocrinological, chromosomal, genetic, or anatomical factors. Identifying and addressing these underlying issues can improve future pregnancy outcomes and prevent further losses.
