Ovulation pain; Midcycle pain
Mittelschmerz is one-sided, lower abdominal pain that occurs in women at or around the time of an egg is released from the ovaries (ovulation).
About 1 in 5 women have mittelschmerz, or pain associated with ovulation. The pain may occur just before, during, or after ovulation.
There are several explanations for the cause of this pain. Just prior to ovulation, follicle growth may stretch the surface of the ovary, causing pain. At the time of ovulation, fluid or blood is released from the ruptured egg follicle and may cause irritation of the abdominal lining.
