In a normal human female, why does menstruation only occurs if the released ovum is not fertilised? Explain.<\/h2>\n

Ans.<\/h3>\n

Menstruation occurs if the released ovum is not fertilized because:<\/h3>\n

When the released ovum is not fertilized:<\/h3>\n
    \n
  1. \n

    The corpus luteum, formed from the ruptured follicle after ovulation, regresses.<\/h3>\n<\/li>\n
  2. \n

    Regression of the corpus luteum leads to a decrease in progesterone and estrogen levels.<\/h3>\n<\/li>\n
  3. \n

    Decreased hormone levels cause vasoconstriction of the spiral arteries in the endometrium.<\/h3>\n<\/li>\n
  4. \n

    Reduced blood flow to the endometrium results in ischemia and tissue necrosis.<\/h3>\n<\/li>\n
  5. \n

    The necrotic endometrial tissue sheds, leading to menstrual bleeding.<\/h3>\n<\/li>\n<\/ol>\n

    In summary, menstruation occurs due to the withdrawal of hormonal support and subsequent shedding of the uterine lining when the released ovum is not fertilized.<\/h3>\n","protected":false},"excerpt":{"rendered":"
