Which term refers to ovulation-related pelvic pain?

• A. Pelvic Inflammatory Disease (PID)
• B. Placenta Previa
• C. Dysmenorrhea
• D. Mittelschmerz

Answer: (D)

Ovulation-related pelvic pain is described by the term Mittelschmerz, which literally means “middle pain.” It happens around the middle of the menstrual cycle when the follicle ruptures and releases an egg, causing a brief, usually unilateral lower abdominal ache that may last from a few hours to a couple of days. The discomfort comes from the follicle rupture and peritoneal irritation from released fluid, not from infection or tissue sloughing. This distinguishes it from other conditions: dysmenorrhea is menstrual cramps that occur with the start of menses, pelvic inflammatory disease involves infection with symptoms like fever and cervical motion tenderness, and placenta previa refers to a pregnancy complication with painless vaginal bleeding. Mittelschmerz is typically benign and self-limited, with treatment focusing on comfort (NSAIDs or heat) if needed.
