Understanding Menopause, Andropause

Male and female bodies undergo certain life cycle processes related to their reproductive organs. While girls and women deal with menstrual cycles throughout their reproductive years, men do not experience menstrual cycles since they lack ovaries, where fertilised eggs grow into a foetus after fusion with sperm. In various countries, girls refer to their menstrual cycle as "chums," meaning friends, as it occurs monthly, typically in a 28-day cycle.
