ovum

Unfertilized reproductive cell

An ovum is a female reproductive cell—an egg.

In humans and other mammals, ova develop in the ovaries; fertilization by a sperm cell produces an embryo.

The term appears mainly in scientific and medical contexts: The ovum travels down the fallopian tube.

Plural: ova.
