In a typical 28-day menstrual cycle, ovulation occurs on approximately which day?

1. The menstrual cycle is divided into the menses, proliferative, and secretory phases. 2. Ovulation marks the transition point between the proliferative and secretory phases. 3. This transition occurs on day 14 of a typical 28-day cycle. 4. Day 1 instead marks the start of menses, not ovulation, so that option is ruled out. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 27 "The Reproductive System", p.1303-1304 §Proliferative Phase_
