Definition and Pronunciation
Egg (also called an ovum, plural ova) is the femalereproductive cell (female gamete) in humans and many other animals. It is produced in the ovaries and can be fertilized by a sperm cell to begin the development of a new individual.
Pronunciation: EG
Easy Explanation
An egg is the female reproductive cell involved in humanreproduction. Normally, one mature egg is released from an ovary during ovulation as part of the menstrual cycle. If a sperm fertilizes the egg, a zygote is formed, which may develop into an embryo and, if pregnancy continues, into a fetus.
If the egg is not fertilized, it breaks down and is shed from the body during menstruation.
Grammatical Formation
- Part of speech: Noun
- Plural form: Eggs

Word Comparisons
Egg vs. Ovum
These terms refer to the same reproductive cell. Egg is the common everyday term, while ovum is the scientific and medical term.
Egg vs. Sperm
An egg is the female reproductive cell produced by the ovaries. A sperm is the male reproductive cell produced by the testes. During fertilization, a sperm joins with an egg.
Egg vs. Embryo
An egg is an unfertilized reproductive cell. After fertilization, the resulting cell divides and develops into an embryo.
Egg vs. Ovary
An egg is a reproductive cell, whereas an ovary is the organ that produces and stores eggs.
Connotations
The word egg has both everyday and scientific meanings. In reproductive biology and medicine, it refers specifically to the female reproductive cell. In everyday English, it more commonly refers to the edible egg produced by birds.
The intended meaning is usually clear from the context.
Meaning with Prepositions
Egg in
Example: A mature egg develops in one of the ovaries.
Egg from
Example: The egg is released from the ovary during ovulation.
Egg by
Example: The egg may be fertilized by a sperm.
Egg during
Example: An egg is usually released during each menstrual cycle.
Real-Life Examples
Healthcare providers may monitor egg development during fertility treatments. Scientists study egg cells to understand fertilization, genetics, and early embryonic development. In in vitro fertilization (IVF), eggs are collected from the ovaries and fertilized with sperm in a laboratory before an embryo is transferred to the uterus.

Connection to Sexuality
The egg plays a central role in human reproduction. During the menstrual cycle, a mature egg is released from an ovary and may be fertilized by a sperm following sexual intercourse or assisted reproductive techniques. If fertilization occurs, the resulting zygote begins the earliest stage of human development.
Learning about the egg helps people understand ovulation, fertility, conception, pregnancy, reproductive health, and the biological processes underlying human sexuality. While the egg is essential for reproduction, sexuality also includes emotional, social, and personal aspects that extend beyond reproduction alone.
