The first day of the monthly menstrual cycle is marked by the start of menstruation, which is the shedding of the lining of the uterus. Option A, memarche, refers to the onset of the first menstrual period at the onset of puberty. Option B is a duplicate option. Option C, gametogenesis, is the process of producing gametes (sperm and egg cells) and is not specifically related to the menstrual cycle. Option E, ovulation, occurs approximately halfway through the menstrual cycle and marks the release of an egg from the ovary.
