Menarche is the first menstrual flow onset of puberty in girls while menopause is the time when ovaries of a woman stop releasing eggs.
Menarche refers to the beginning of a woman's reproductive ability and menopause refers to its end.
The time between menarche and menopause. Varies from about 13 to 15 and 45 to 55. (But there are exceptions)
The menarche. The last one is called the menopause.
Imagine menopause like menarche (first period) in reverse - menstruation can just stop then never start again during menopause, but in most cases women going through menopause will experience irregular periods and irregular bleeding between periods, just like pubecent girls do when they start menstruating.
For most women, "periods" are not precisely periodic... they vary slightly in length from cycle to cycle. This is especially true at the beginning and end ... at menarche and menopause.
Everything seems to have a beginning and an end so fertility in a woman has to start and end somewhere & Menarche is the word we give to the beginning & Menopause is the word we give to the end. Between the two will be most of her life and all of her reproductive, child bearing years. OK the basics; Menarche is from the Greek meaning BEGINNING & is the term commonly used for the onset of the first period for a girl. That first period indicated the onset of fertility. Getting the first period is a big deal for most girls and is a date most remember throughout their life. For many it is the symbolic "coming of age, becoming a woman, moment". The average age for Menarche in most girls will be somewhere in the 12th year. & that fertility will continue until the FERTILITY cycle of life has run its course for that woman, that end of cycles is called MENOPAUSE. Unlike the onset of fertility, Most women will be in MENOPAUSE for several years and it does not come at a precise moment. MENOPAUSE IS A PROCESS THAT USUALLY TAKES A FEW YEARS. ERRATIC MONTHLY CYCLES, MORE THAN A YEAR WITHOUT A CYCLE, THE END OF FERTILITY, LOW TESTOSTERONE & ESTROGEN, HOT FLASHES, JOINT PAIN, VAGINAL DRYNESS & A LOSS OF SEX DRIVE ARE ALL INDICATORS OF MENOPAUSE. ...
Because those words are what we call the beginning and ending of the reproductive phase of a woman. You might as well say "Why does life begin at conception and end at death?"
Menarche is the term used to describe a woman's first period.
Menstruation is a monthly event of the uterus shedding it's lining. It begins at menarche (first period, usually about age 13) and continues until the onset of menopause (usually mid to late 40's). Menopause begins a change in the body where periods become at first, erratic, then infrequent, and finally stop all together. Past this point, the woman is considered no longer able to bear children.
