Explain the role of Fillicle Stimulating Hormone (FSH), Lutenising Hormone, Oestrogen and Progesterone in the menstural cycle - Essay Example The reproductive system of females is quite different from males. In females the egg production is a periodic or cyclic activity (menstrual cycle) while in males the production of sperms is a continuous process and never stops after they hit puberty till the time they die. In human females the periodic reproductive menstrual cycle is controlled by certain hormones and is completed in approximately twenty eight days causing changes in structure as well as the function of the entire reproductive system. The menstrual cycle in total comprises of the ovarian cycle linked with ovaries and the uterine cycle linked with uterus. We can divide the menstrual cycle into four main phases which are: The pituitary gland naturally produces the follicle stimulating hormone which is secreted in blood. By the name we can very well guess that this follicle stimulating hormone is linked with the follicle phase. The hormone is mainly responsible for the growth of the ovarian follicle or for stimulating the development of several primary follicles and also for stimulating the ovary to produce its own hormone which is called the oestrogen from the ovarian follicles which degenerate during the initial process of follicle phase (follicle atresia) and the oestrogen then is responsible for the thickening and vascularizing of the endometrium (uterus wall) before the process of ovulation actually starts and at the same time inhibits the pituitary to stop the production of follicle stimulating hormone. In males, the follicle stimulating hormone is also plays an important role in the production of sperm by supporting steroli cells in their function.(the menstrual cycle1993; Mayo Clinic 2011; R. Bowen 2004) When the level of the follicle stimulating hormone becomes less while the level of estrogen increases the pituitary gland secretes another hormone which is
