During which phase of the ovarian cycle is an egg typically released?

The release of an egg occurs during the ovulation phase of the ovarian cycle. This phase marks a critical event in the cycle where a mature egg is expelled from the ovary, typically around the middle of the menstrual cycle, usually occurring about 14 days before the next menstruation starts. Ovulation is triggered by a surge in luteinizing hormone (LH) levels, which is preceded by an increase in follicle-stimulating hormone (FSH) that stimulates the growth of ovarian follicles. During this phase, one dominant follicle matures, leading to the release of the egg, and is a key moment for potential fertilization should sperm be present. This understanding is crucial for comprehending reproductive health and fertility.
