These changes are closely associated with the functions of the axis hypothalamus-pituitary-ovary. They start at about 6 years before menopause. Increases when the concentration of hormones secreted by the pituitary gland – follicle stimulating hormone (FSH) and luteinizing hormone (LH) that regulate ovarian function. The process of reduction in ovarian function may begin to have between 35 and 40 years of age. Occurs to reduce the sensitivity of the ovaries to the pituitary hormones mentioned above, what are the consequences of impaired development of ovarian follicles and anovulatory cycles show.

At this time there is also a reduction in the concentration of hormones secreted by the ovaries – estrogen and progesterone – a characteristic change of proportion between them. The closer to menopause, the bleeding is more scarce. The closer to menopause, the bleeding is more scarce, time between periods can extend up to several months. During this period there is a likelihood of a single ovulatory cycles, hence the necessity arises to consider an appropriate contraceptive method.
