Why does a Graafian follicle, dominant prior to ovulation, sometimes fail to release the oocyte even when LH surges?

💡 Explanation

Ovulation requires proteolytic enzymes to weaken the follicle wall. Without adequate production, the oocyte can't be released, even with an LH surge, because the follicle doesn't rupture; therefore, the oocyte remains trapped within the follicle rather than being expelled into the fallopian tube.
