Everything starts in the brain, from where the impulses that stimulate the ovaries to produce hormones. These hormones, in a cyclic manner, and will stimulate the endometrium flake off in the form of menstruation. The endometrium is the tissue within the uterine cavity which has the function of implanting the fertilised eggs, which dissolves in the form of menses does not occur if pregnancy.
This cyclical orchestration of monthly hormones that occurs in women is preparing for pregnancy. Previously, little woman menstruated, being pregnant or nursing most of the time. It was a time a few periods and many children.
Currently, there are new drugs and techniques which seek to control more efficiently the menstrual cycle.

From this, the human being could dissociate sex from procreation, with all the socio-economic and cultural impact of this change, and passed the time of many periods with few children with more advanced age pregnancies. But that may predispose to some diseases such as endometriosis and fibroid.
Most women menstruate without major difficulties. Some diseases such as endometriosis, fibroid, bleeding disorders and women with greater sensitivity to hormonal fluctuations can present numerous problems from behavioural (TPM) to undertake normal activities caused by pain and / or intensity of bleeding.

However, the use of contraceptive implant and no use menopause, once the will mature in the same way. In general, only surgical procedures that compromise the ovary interfere with the onset of menopause, arriving early on.
