What is the medical term for a woman who has given birth to one or more viable offspring?

The term 'Para' refers to a woman who has given birth to one or more viable offspring, regardless of whether those offspring are alive or stillborn. This classification is part of the obstetrical history of a woman and is used to describe her reproductive history in a concise manner.

For clarity, 'Nullipara' refers to a woman who has never given birth, which does not relate to the question about someone who has delivered viable offspring. 'Primipara' is used to describe a woman who has given birth for the first time, and 'Multipara' refers to a woman who has given birth multiple times. While both 'Primipara' and 'Multipara' describe specific groups of women based on their childbirth experiences, 'Para' serves as the general term encompassing all women who have delivered at least one viable baby. This makes 'Para' the correct answer in the context of the question.
