More About Menarche

In some cultures, menarche and the transition to womanhood that it signifies are celebrated with specific rituals, parties, and even foods. Because menarche is sometimes thought of as a "coming of age," it is also the point after which young women of some cultures are paired off with their prospective mates. For some cultures, the topic of menstruation is taboo and young women may know very little about what is happening to their body during menarche and its connection to sexuality.
