Human females typically release one ovum during each menstrual cycle.
The ovum contains half of the genetic material needed to form a new individual.

Fertilization occurs when a sperm cell penetrates the protective layers of the ovum.
During ovulation, a mature ovum is released from the ovary and travels down the fallopian tube.
