Which term means infrequent or very light menses?

• A. Oligomenorrhea
• B. Polymenorrhea
• C. Metrorrhagia
• D. Menometrorrhagia

Answer: (A)

Understanding how menstrual bleeding patterns are described helps identify the term for infrequent menses. Oligomenorrhea means infrequent menses, with cycles spaced out and typically lasting more than 35 days. Sometimes it’s described as very light flow, but the main feature is the extended interval between periods. In contrast, bleeding every shorter interval describes polymenorrhea; metrorrhagia refers to bleeding at irregular times between periods; and menometrorrhagia means heavy bleeding that occurs irregularly. Therefore, the description infrequent or very light menses fits oligomenorrhea.
