menstrual cycle

what is the menstural cycle?

The menstural cycle is when a hormone that is created. For example each month a woman releases and egg from the ovaries. If this egg is not fertilised then it sticks to the side of the uterus wall and sticks to the lining of blood. Each month when the egg is not fertilised the woman then has a period. However a man creates a hormone called testosterome.
