**Core Concept**
Recurrent miscarriage, also known as recurrent pregnancy loss, is a condition where a woman experiences repeated miscarriages. This condition is often defined based on the number of consecutive miscarriages. The underlying principle being tested is the definition of recurrent miscarriage in the context of **obstetrics** and **gynecology**.

**Why the Correct Answer is Right**
The correct answer is based on the definition provided by the American Society for Reproductive Medicine (ASRM), which states that recurrent miscarriage is defined as the loss of three or more consecutive pregnancies. This definition is used to distinguish recurrent miscarriage from sporadic miscarriage and to guide further evaluation and treatment. The **hormonal**, **genetic**, and **anatomical** factors contributing to recurrent miscarriage are complex and multifactorial.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not align with the ASRM definition.
**Option B:** This option is also incorrect as it underestimates the number of consecutive miscarriages required for the definition.
**Option C:** This option is incorrect because it overestimates the required number of miscarriages.

**Clinical Pearl / High-Yield Fact**
Recurrent miscarriage is a significant concern for women of reproductive age, and its definition is crucial for guiding further evaluation and treatment. It is essential to remember that the definition of recurrent miscarriage is three or more consecutive miscarriages, which helps to identify women who require closer monitoring and intervention.

**Correct Answer:** D. Three or more consecutive miscarriages.
