Menopause
Description of Menopause:
The Menopause is the permanent cessation of menstruation which occurs a
considerable length of time before the end of the lifespan.
The word was first applied to humans, and because of this it literally means
the cessation of monthly cycles or menstrual cycles, from the Greek roots meno (meaning
month, referring to monthly menstruation) and pausis (a halt). However,
currently the word is used in a broader sense, and menopause is the permanent
stopping of female reproductive cycles of various lengths and kinds; menopause
is indeed present in a number of vertebrate species other than humans.
In adult human females who still have a uterus, and who are not pregnant or
lactating, postmenopause is identified by a permanent (at least one year's)
absence of monthly periods or menstruation. In women without a uterus, menopause
or postmenopause is identified by a very high FSH level.
In human females, menopause usually happens more or less in midlife,
signaling the end of the fertile phase of a woman's life. Menopause is perhaps
most easily understood as the opposite process to menarche, the start of the
monthly periods. However, menopause in women cannot satisfactorily be defined
simply as the permanent "stopping of the monthly periods", because in reality
what is happening to the uterus is quite secondary to the process; it is what is
happening to the ovaries that is the crucial factor.
For medical reasons, the uterus must sometimes be surgically removed (hysterectomy)
in a younger woman; her periods will cease permanently, and the woman will
technically be infertile, but as long as at least one of her ovaries is still
functioning, the woman will not have reached menopause; even without the uterus,
ovulation and the release of the sequence of reproductive hormones will continue
to cycle on until menopause is reached. But in circumstances when a woman's
ovaries are removed (oophorectomy), even if the uterus were to be left intact,
the woman will immediately be in "surgical menopause".
Thus menopause is based on the natural or surgical cessation of hormone
production by the ovaries, which are a part of the body's endocrine system of
hormone production, in this case the hormones which make reproduction possible
and may influence sexual behavior. The resultant decreased levels of circulating
estrogen impacts the entire cascade of a woman's reproductive functioning, from
brain to skin.
The menopause transition, and post-menopause itself, is a natural life change,
not a disease state or a disorder. The transition itself can be challenging for
a number of women, but for others it is not difficult.
