Ovum
01
卵子, 卵细胞
a mature, female reproductive cell or egg, typically larger than a sperm cell, capable of fusing with a sperm cell during fertilization to form a zygote

Human females typically release one ovum during each menstrual cycle.
Fertilization occurs when a sperm cell penetrates the protective layers of the ovum.
The ovum contains half of the genetic material needed to form a new individual.
