| Definition / notes: | The approximately four-weekly oestrous cycle in human females associated with the release of an egg from the ovary (ovulation) and the preparation of the wall of the uterus in readiness for a fertilized egg. The cycle is under the control of hormones involving secretions from the pituitary gland and the ovaries themselves. The various interactions between the hormones provide a good example of feedback control. If no fertilized egg is present, the lining of the uterus breaks down and passes out through the vagina over a period of five or six days (a 'period') during menstruation. |
