Which term denotes a pregnancy involving three or more embryos or fetuses?

• A. High-order births
• B. High-order multiple gestation
• C. Hydrosalpinx
• D. High-order multiple gestation

Answer: (D)

Three-or-more-fetus pregnancies are described as high-order multiple gestation. “Gestation” ties the term to the pregnancy period, and “high-order” signals three or more fetuses, which distinguishes these pregnancies from twins or a singleton pregnancy. The other options either refer to the delivery event (births) or describe an unrelated condition (hydrosalpinx), so they don’t label the pregnancy state. The standard term in obstetrics for a pregnancy with three or more fetuses is high-order multiple gestation.
