Menstrual Cycle Physiology Ppt File

The climax of the cycle, ovulation, deserves a dedicated slide. The key physiological concept here is the "LH surge." The presentation must explain the mechanism of the positive feedback loop: as estrogen levels from the dominant follicle exceed a specific threshold for a sustained period, it triggers a massive release of LH from the pituitary.
