THE MENSTRUAL CYCLE
Each menstrual cycle represents a complex interaction between the hypothalamus, pituitary gland, ovaries, and endometrium. Cyclic changes in gonadotropin and steroid hormones induce functional as well as morphologic changes in the ovary, resulting in follicular maturation, ovulation, and corpus luteum formation. Similar changes at the level of the endometrium allow for successful implantation of the developing embryo.
The reproductive cycle can be viewed from the perspective of each of the aforementioned organ systems. The cyclic changes within the hypothalamic-pituitary axis, ovary, and endometrium are approached separately in this chapter, but these endocrinologic events occur in concert in a uniquely integrated fashion. In addition, fertilization, implantation, and placentation are discussed.
