Ovulation: Generally speaking of follicle is able to rupture and emit the eighth at approximately 18 mm or greater. Nature is funny and full of variability and some sure there are follicles that rupture at an even smaller size and sometimes we see follicles as big as 30 mm that then ovulate spontaneously. I hope this helps.
