Which product of conception shows no evidence of life after expulsion or extraction?

The product of conception that shows no evidence of life after expulsion or extraction is fetal death. This term refers specifically to the loss of a fetus at any time during the pregnancy, recognized as occurring after 20 weeks of gestation, when the fetus has passed away before or during delivery. In these cases, despite the fetus being expelled from the womb, there are no signs of life present, such as heartbeat or respiratory function.

The other options pertain to different states of life and development. Live birth indicates that the newborn has shown vital signs, such as breathing or heartbeat, after delivery. Premature birth refers to a birth that occurs before the 37th week of pregnancy but does not by itself indicate evidence of life or lack thereof. A neonate is an infant who is less than 28 days old and is inherently associated with being alive after birth.

Fetal death, therefore, is the only option that specifically refers to a situation where no evidence of life exists immediately after the expulsion or extraction.
