Need help with my writing homework on Anatomy and Physiology. Write a 2750 word paper answering; In case of fertilization, the egg is implanted in the uterine lining which consequently stops the menstruation cycle to occur again during the term of pregnancy. The ovarian cycle does not repeat if the oocyte becomes fertilized. After fertilization and conception, the process of embryo development starts which causes an end to the ovarian cycle all through the term of pregnancy. Part b On the other hand, a new oocyte matures during the next ovarian cycle if fertilization does not occur. The uterine lining also becomes thin and breaks down which causes menstruation to occur again. The egg which is released from the ovary needs approximately 12 to 48 hours to be fertilized. If fertilization does not occur, the egg disintegrates. After almost two weeks of this process, menstruation begins again upon shedding of the thick uterus lining. The lining of the uterus is there to support the pregnancy. However, when there is no fertilization, the lining breaks down and sheds in response of which the next cycle of menstruation begins. To state it all in more academic medical terms, one can say that after a couple of weeks approximately, the corpus luteum involutes if fertilization does not occur.
