To be informative, this graph must accurately represent the temporal relationship between events. For example, the peak of LH must align with day 14, and the rise in basal body temperature should correspond with the post-ovulatory rise in progesterone. Color-coding the hormone lines helps the audience track the distinct rise and fall of each chemical messenger.
The physiology of the corpus luteum is critical; it produces progesterone to maintain the endometrium for potential implantation. The presentation should explain the lifespan of the corpus luteum (approximately 14 days) and the event of luteolysis (degeneration) if pregnancy does not occur. The decline in progesterone and estrogen removes the negative feedback on the HPO axis, leading to a rise in FSH and the initiation of a new cycle. menstrual cycle physiology ppt
The remains of the ruptured follicle transform into the . To be informative, this graph must accurately represent
A strong presentation often includes common disorders related to cycle physiology: Absence of menstruation. Dysmenorrhea: Painful menstruation. PCOS: Hormonal imbalance causing irregular cycles. Conclusion The physiology of the corpus luteum is critical;
Finally, the presentation must address menstruation itself (the menses). The slide should explain that the withdrawal of progesterone causes vasoconstriction of the spiral arteries, leading to ischemia and shedding of the functional layer of the endometrium.
If pregnancy doesn't occur, the corpus luteum withers, hormone levels drop, and the cycle restarts. 4. The Uterine (Endometrial) Cycle
: This rising estrogen triggers the Proliferative Phase in the uterus, where the lining begins to thicken and regrow in anticipation of an egg. Phase 2: Ovulation (Day 14)
