Shortcut Methods

Menstrual Cycle:

1. Menstrual Phase (Days 1-5): Menstruation begins with the shedding of the uterine lining. It lasts 3 to 7 days.

2. Follicular Phase (Days 1-13): Follicle-stimulating hormone (FSH) stimulates ovarian follicles to develop. Usually, one dominant follicle matures.

3. Ovulatory Phase (Day 14): Luteinizing hormone (LH) surge triggers ovulation, the release of a mature egg from the dominant follicle.

4. Luteal Phase (Days 15-28): The ruptured follicle becomes the corpus luteum, producing progesterone. This phase prepares the uterus for potential pregnancy.

5. Hormonal Regulation: Hormones, including FSH, LH, estrogen, and progesterone, tightly regulate the cycle.

6. Cycle Length: The average menstrual cycle is around 28 days, with variations considered normal (21-35 days).

7. Menstruation and Fertility: Menstruation indicates a healthy reproductive system. Conception is possible during the fertile window around ovulation.
