CHAPTER ONE INTRODUCTION 1.0 BACKGROUND OF THE STUDY Menstrual cycle is a process experienced by every female at one point in their life cycle.

The age at menarche (the first time a girl or a young woman menstruates) is widely considered as an important landmark in sexual maturity. However it varies widely between

The menstrual cycle is a cyclic process in females that‚ on average‚ occurs every 28 days. The purpose of the menstrual cycle is to help prepare the body for potential fertilization‚ implantation‚ and‚ consequently‚ pregnancy. The happenings of the menstrual cycle are consequences of the simultaneously occurring ovarian cycle and uterine cycle. The ovarian cycle occurs in the ovaries and carries out the follicular phase‚ which spans the first 14 days of a new menstrual cycle. The result is ovulation

4Action of hormones in the Menstrual Cycle The Ovarian Cycle The cycle begins with the release from the hypothalamus of gonadotrophin – releasing hormone (GnRH)‚ which stimulates the pituitary to secrete small amounts of Follicle Stimulating Hormone (FSH) and Luteinising Hormone (LH). The FSH stimulates follicle growth‚ aided by LH and the cells of the growing follicles start to make estrogen. Notice in figure(d) that there is a slow rise in the amount of estrogen

of hormones. Hormones are chemicals that are in the body‚ that are released when the brain tells them that it is time for the body to change‚ and grow. Hormones will play a big role in the way your body functions for the rest of you life. But now we will focus on how certain hormones work together to make us all beautiful women. Since you were born‚ you have had two little sacs in side of you‚ near your stomach called ovaries. These ovaries have several roles to play. They produce hormones‚ which

In endometriosis‚ displaced endometrial tissue continues to act as it normally would: It thickens‚ breaks down and bleeds with each menstrual cycle. And because this displaced tissue has no way to exit your body‚ it becomes trapped. Surrounding tissue can become irritated‚ eventually developing scar tissue and adhesions‚ which is the abnormal tissue that binds organs together (Staff‚ 2010)
