primary sex character
Definition
Noun The genetically determined physical characteristics directly involved in reproduction, specifically the reproductive organs (genitals) and associated glands.
Usage

- During embryonic development, the primary sex characters are formed.
- A medical examination confirmed the infant's primary sex characters were typically male.
Advanced Usage

- It is a more formal and precise alternative to phrases like "primary sexual characteristics" or "sex organs."
Variants and Related Words

- Secondary sex character/characteristic: Refers to traits that emerge during puberty (e.g., breast development, facial hair) but are not directly part of the reproductive system.
Synonyms

Related Concepts
