Micropenis is defined as which of the following?

• A. Abnormally wide penis
• B. Short scrotum
• C. Abnormally short or thin penis
• D. Normal length but small glans

Answer: (C)

Micropenis is defined by an abnormally small penis, typically identified by a stretched penile length that is significantly below the normal range for age or development. This size deficit can manifest as an abnormally short penis, and in some cases (though not routinely required for the definition) may relate to reduced girth as well, hence the wording “short or thin.” It is not about width, scrotal size, or a normal-length penis with a small glans, which describe different issues.
