Human Ovulation

Laparoscopic observation of spontaneous human ovulation. A remarkably prominent vascular pattern was observed on the mature follicle (F, white arrows).

A small follicular area called the stigma (S) was seen protruding like a reddish bleb from the follicular surface, with viscous yellow fluid (black arrows) evaginating outward into the peritoneal cavity.

The viscous fluid probably carried with it the cumulus–oocyte complex, surrounded by several thousand small granulosa cells known as corona radiata.
