Buy NowFrom The Biology of Prenatal Development.

Script: A woman's reproductive cell is commonly called an "egg" but the correct term is oocyte.

Likewise, a man's reproductive cell is widely known as a "sperm" but the preferred term is spermatozoon.

Following the release of an oocyte from a woman's ovary in a process called ovulation, the oocyte and spermatozoon join within one of the uterine tubes, which are often referred to as Fallopian tubes.

The uterine tubes link a woman's ovaries to her uterus or womb.

The resulting single-celled embryo is called a zygote, meaning "yoked or joined together."

All ages referenced to fertilization, not last menstrual period.
