what causes ovulation pain
Causes of Mittelschmerz or Ovulation Pain or Midcycle Pain. Before the release of the egg with ovulation, the growth of the follicle causes the surface of the ovary to stretch resulting in pain. The ruptured follicle may cause release of blood or fluid leading to irritation of the abdominal lining (peritoneum) and causing pain.
1 doctor agreed: Mittelschmerz: ovulation pain (mittelschmerz) is cause by first the actual rupture of the cyst causing a sharp sudden pain with some residual discomfort afterwards. But many ovulated cysts will also bleed slightly and the blood irritates the perineum causing often a couple days of crampy to sharp pain.
