What occurs during ovulation?

During ovulation, the primary biological event that takes place is the release of a developed egg, or oocyte, from the ovary. This process is crucial for reproduction, as it allows for the possibility of fertilization. The egg matures within the ovarian follicle, and upon reaching a certain stage of development, hormonal changes trigger ovulation, allowing it to be released into the fallopian tube. This event typically occurs midway through the menstrual cycle in mammals and is essential for the progression of potential conception. Without this release, fertilization cannot occur since there would be no egg available for sperm to fertilize.
