During which phase does ovulation occur in the menstrual cycle?

Ovulation occurs during the proliferative phase of the menstrual cycle. This phase follows the end of menstruation (the menses phase) and is characterized by the thickening of the endometrial lining in preparation for a potential pregnancy. It is during this time that the dominant follicle in the ovary matures, ultimately leading to the release of an egg—a process known as ovulation.

This release typically occurs mid-cycle, around day 14 in a standard 28-day cycle, after a surge in luteinizing hormone (LH). The proliferative phase directly supports the physiological changes that prepare the body for possible conception, making it a critical part of the menstrual cycle.

Understanding the timing of ovulation is essential for both conception efforts and overall reproductive health, as it signifies the window of highest fertility.
