2. The Menstrual Cycle
The menstrual cycle is the cyclical change occurring in the female reproductive tract that allows pregnancy to be possible. This cycle is necessary for the production of the oocyte (egg) and to prepare the body for pregnancy. The length of the menstrual cycle varies for each woman.
Those with less than 8 days difference between their longest and shortest cycle are considered to have a regular cycle. A difference of 8 to 20 days is considered to be moderately irregular while a variation of more than 21 days is considered to be very irregular. An average menstrual cycle lasts 28 days. The menstrual cycle can be described by the ovarian cycle and uterine cycle.
