Dear student

Menstrual Cycle

  • Menstruation occurs in human, apes and old world monkeys.

  • Menstruation is bleeding from the uterus of adult females at intervals of one lunar month.

  • Beginning of menstruation or first menstruation is called menarche.

  • The beginning of menstruation varies. It usually occurs between 12 and 15 years.

  • The cycle of events starting from one menstruation till the next one is called Menstrual Cycle.

  • In human females, menstruation is repeated at an average interval of about 28/29 days.

  • One ovum is released (ovulation) during the middle of each menstrual cycle.

  • It is regulated by certain hormones, some of which are secreted by the pituitary gland.

  • The pituitary gland is stimulated by releasing factors produced in the hypothalamus.

  • The hormones produced by the pituitary gland influence the ovaries. The hormones secreted by the ovaries affect the walls of the uterus.
