Menarche
Explanation:
Between the age of 11 to 15 years, females experience the onset of menstruation. The reproductive system starts producing the egg or ovum. Onset of menstruation is called Menarche. Once a female attains puberty, she menstruates every month. An egg or ovum is produced by the ovary every month. If this egg is not fertilized by a sperm, then the unfertilized egg and endometrium is removed as waste through menstruation. This cycle continues until the female gets pregnant. When a female is pregnant, she does not menstruate. Menstruation resumes after delivery and continues every month, absent a pregnancy, until the female attains menopause. Each menstrual cycle is about 28 to 35 days. The day of menstrual flow marks the first day of the cycle and the flow could last 3 to 5 days.
