It is the result of the eventual [[atresia]] of almost all oocytes in the ovaries.  This causes an increase in circulating [[Follicle-stimulating hormone|follicle stimulating hormone]] (FSH) and [[luteinizing hormone]] (LH) levels as there are a decreased number of [[oocyte|oocytes]] responding to these hormones and producing estrogen.  This decrease in the production of estrogen leads to the perimenopausal symptoms of hot flashes, insomnia, and mood changes, as well as post-menopausal [[osteoporosis]] and [[vaginal atrophy]].

However, menopause can be surgically induced by bilateral salpingo-oophorectomy (removal of both ovaries and both fallopian tubes), which is often, but not always, done in conjunction with [[hysterectomy]]. Cessation of menses as a result of removal of the ovaries is called "surgical menopause". The sudden and complete drop in reproductive hormone levels usually produces extreme hormone-withdrawal symptoms such as hot flashes, etc.
 
As mentioned above, removal of the uterus, hysterectomy, does not itself cause menopause, although pelvic surgery can sometimes precipitate somewhat earlier menopause, perhaps because of compromised blood supply to the ovaries. Removing the ovaries, however, causes an immediate and powerful "surgical menopause", even if the uterus is left intact.

Risk calculators and risk factors for Menopause causes

Overview

Menopause occurs naturally or can be induced, Induced menopause happens as a result of bilateral oophorectomy, hysterectomy, salpingo-oophorectomy, a complication of tubal ligation, complications of treatment, such as chemotherapy and radiotherapy, autoimmune diseases such as thyroid disease, rheumatoid arthritis, Turner’s syndrome, myalgic encephalomyelitis/chronic fatigue syndrome, polycystic ovary syndrome, premature ovarian insufficiency Several risk factors accelerate happen early menopause such as undiagnosed and untreated coeliac disease, family history and Cigarette smoking has been found to decrease the age at menopause by as much as one year and women who smoke have early menopause before non-smoking women.[1][2]

causes

  • Age:

As women age, physiological menopause happened is the result of the eventual atresia of almost all oocytes in the ovaries and deficiency of estrogen and progesterone hormone production.

  • Certain health conditions:
  1. Autoimmune diseases, such as thyroid disease and rheumatoid arthritis the body’s immune system, attack the ovaries, and keep them from making hormones.
  2. HIV and AIDS, Women with HIV whose infection is not well controlled with medicine may experience early menopause.4 Women with HIV may also have more severe hot flashes than women without HIV.
  3. Missing chromosomes, such as Turner’s syndrome, women are born without all or part of one X chromosome, so their ovaries do not form normally at birth and their menstrual cycles, including the time around menopause, may not be normal.
  4. Chronic fatigue syndrome, Women with chronic fatigue syndrome are more likely to have early or premature menopause.
  • Chemotherapy or radiotherapy:.

These cancer treatments can damage your ovaries and cause your periods to stop forever or just for a while.

  • Surgical causes:
  1. Bilateral oophorectomy and salpingo-oophorectomy, periods will stop after this surgery, and hormone levels will drop quickly with strong menopausal symptoms.
  2. Hysterectomy, removal of the uterus, hysterectomy, does not itself cause menopause, although pelvic surgery can sometimes precipitate somewhat earlier menopause, perhaps because of compromised blood supply to the ovaries.Women who have undergone hysterectomy with ovary conservation go through menopause 3.7 years earlier than average.
