The Menstrual Cycle And Periods Of Fecundity. From The Top To The Bottom Ovarian Cycle, Uterine Cycle And Curve Of Temperature. The Menstrual Cycle Is Divided Into Three Phases The Follicular Phase Or Proliferative, Pre Ovulatory, The Luteal Phase Or Secretory, Post Ovulatory And The Menstruation Menses. The Follicular Phase :Inside The Ovary, The Ovarian Follicles, Carrying The Ovocytes, Develop Primordial Follicle, Primary, Secondary And Tertiary. A Cavitary Follicle Carries Out Its Maturation By Cycle, It Is The Graafian Follicle. This Follicle Secrete Estrogens, Of Which The Rate Will Then Progressively Increase. On The Fourteenth Day Of The Cycle, The Mature Tertiary Follicle Or Graafian Follicle Ejects The Ovocyte Ii It Contains It Is Ovulation. At The Level Of The Uterus, The Endometrium Is Preparing To Receive A Possible Embryo It Thickens And The Uterine Glands Develop. The Corporal Temperature Is Stable Between 36. 5 And 37°C In General. The Luteal Phase :Inside The Ovary, The Graafian Follicle Emptyied Of Its Content, Or Dehiscent Follicle, Degenerates Into Corpus Luteum Follicular Atresia. It Produces Estrogens And Progesterone. The Progesterone Acts Indirectly On The Centers Of The Hypothalamus Thermic Regulation, Causing An Increase Of A Few Dozen Of Degrees Of The Body Temperature. This Elevation Pursues During 12 To 14 Days, It Is The Thermal Plate. Within The Uterus, The Endometrium Pursues Its Maturation, And The Uterine Glands Secrete Glycogen For The Possible Nutrition Of The Futur Embryo. The Menstruation :In Absence Of Fertilization, The Corpus Luteum Disappear. The Estrogen And Progesterone Assure The Maintain Of The Uterine Mucous Membrane, The Drop In Their Blood Rates Trigger Menstruation. (Photo By BSIP/UIG Via Getty Images)
