Summary Introduction

To determine: The effect of administration of aromatase inhibitor on the ovarian cycle of women.

Introduction: Menstrual cycle is a series of events in which hormonal changes take place in females’ ovary and uterine wall. The menstrual cycle is formed from the combination of two different cycles, ovarian cycle, and uterine cycle. The uterine cycle is divided into three different phases, which are menstruation, proliferative, and secretory phase. Estrogen is important for the proliferative phase because it induces mitosis in the basal layer as well as it allows the re-growth of blood vessels.
