What term describes painful menstruation?

The term that describes painful menstruation is dysmenorrhea. However, among the provided options, menorrhagia, which refers to excessively heavy or prolonged menstruation, might seem like a close option, but it is not synonymous with painful menstruation.

Understanding this, dysmenorrhea occurs when women experience cramping pain during their menstrual period due to various causes, such as hormonal imbalances, uterine conditions like endometriosis, or other underlying health issues. Menorrhagia focuses specifically on the volume and duration of menstrual flow rather than the pain involved. Metrorrhagia refers to bleeding between menstrual periods, and orchitis relates to inflammation of the testes. A pessary is a device used to support pelvic organs, so it also does not pertain to menstrual pain.

Therefore, in your understanding of menstrual disorders, it is crucial to differentiate between terms based on their specific implications regarding menstruation.
