Shortcut Methods
Menstrual Cycle:
-
Menstrual Phase (Days 1-5): Menstruation begins with the shedding of the uterine lining. It lasts 3 to 7 days.
-
Follicular Phase (Days 1-13): Follicle-stimulating hormone (FSH) stimulates ovarian follicles to develop. Usually, one dominant follicle matures.
-
Ovulatory Phase (Day 14): Luteinizing hormone (LH) surge triggers ovulation, the release of a mature egg from the dominant follicle.
-
Luteal Phase (Days 15-28): The ruptured follicle becomes the corpus luteum, producing progesterone. This phase prepares the uterus for potential pregnancy.
-
Hormonal Regulation: Hormones, including FSH, LH, estrogen, and progesterone, tightly regulate the cycle.
-
Cycle Length: The average menstrual cycle is around 28 days, with variations considered normal (21-35 days).
-
Menstruation and Fertility: Menstruation indicates a healthy reproductive system. Conception is possible during the fertile window around ovulation.
