The irregular menstruation or ovulation disorder is characterized by menstrual cycles that do not follow a similar pace each month, making the detection of fertile period and design.
In general menstrual cycles vary between 21-40 days and more regular cycle would be one of just 28 days. But it is natural that the intervals between menstrual periods are longer in the years immediately following the first period, as in previous years close to menopause.
Menopause is the term used to designate the time of the last menstruation, when the ovaries are not releasing more eggs for and ultimately the production of the estrogen, which is the hormone most active in the reproductive life of women.
The date of menopause is determined by genes that each woman brings heritage. But just as menarche is genetically determined and some girls come to her with 10 years and others at 16, the age of the first signs approximation of the last menstruation varies between 45 and 47 years and the end of the entry process or the menopause itself, occurs between 48 and 51 years.
The early onset of puberty and first menstruation does not influence the age of the last menstruation. This approach, considered true until recently is proved unfounded today. Theses such as this, that the period fertility the woman does not ever exceed 30 years after the first period, or menarche, also fell to the ground because they have no scientific evidence. Today, medical science knows that the age of first menstruation has nothing to do with the arrival menopause.
The number of pregnancies, the fact of having breastfed or not last pregnancy and the age of either influence the age of menopause. The only association, confirmed in scientific studies, is that obese women may have their last period slightly later. Women smokers, or who never had children or who has a history of depression would be subject to entering menopause two to three years earlier, according to polls.
The mother's age at menopause may be a reference to evaluate the time the child reaches menopause. But it can not be taken as a rule. Just as studies of families who have menopause Premature not necessarily indicate that future generations enter menopause early. Eating habits and style of life are other factors that interact with genetic inheritance to determine the age of menopause.
Only You can be sure of the arrival of twelve months after menopause the last period, the absence of menstruation over a year definitively closes the female reproductive phase.
Keep using a contraceptive method during the transition for menopause, ie, throughout perimenopause and keep it up one year after the last menstrual period is crucial for those who do not want any surprises at this age. There are cases of women who became pregnant during this period of twelve months, although not menstruate more. They are rare, but they are there to prove that all be too careful when it comes to the functioning of the ovaries.
