Release of a secondary oocyte from the ovary triggered by a surge in luteinising hormone.
The follicle ruptures, releasing the oocyte surrounded by cumulus cells, which is swept into the fallopian tube. The ruptured follicle becomes the corpus luteum. Fertile window is about 5 days.
Ovulation is triggered by the LH surge. Basal body temperature rises after ovulation. The oocyte survives about 24 hours.
Remember: ovulation is mid-cycle in a 28-day cycle.
