History and exam
Key diagnostic factors
common
age <40 years
Beyond age 40, menopause is considered to be physiologically normal.
family history of primary ovarian failure
menstrual irregularities
May present most commonly with amenorrhoea (primary or secondary), but can occur with abnormal uterine bleeding or irregular bleeding patterns.
uncommon
toxic exposures
Mumps, chemotherapy, radiation, tobacco, and other toxins.
Other diagnostic factors
common
hot flushes
Symptom of oestrogen deficiency, although patients may be asymptomatic.
sleep disturbance
Symptom of oestrogen deficiency, although patients may be asymptomatic.
irritability
Symptom of oestrogen deficiency, although patients may be asymptomatic.
vaginal dryness
Symptom of oestrogen deficiency, although patients may be asymptomatic.
infertility
Diminished ovarian function often results in infertility; however, intermittent ovarian function, ovulation, and pregnancy can occur.
vaginal atrophy
Common with long-standing oestrogen deficiency. May be noted on physical examination.
small uterus with non-palpable ovaries
Common with long-standing oestrogen deficiency. May be noted on physical examination.
uncommon
cognitive abnormalities
Carriers of fragile X premutation may show mild cognitive or behavioural impairment.
signs of thyroid dysfunction
The possibility of a goitre, exophthalmos, lid lag, abnormal heart rate, or skin changes should be sought.
signs of adrenal dysfunction
Evidence of adrenal insufficiency (Addison's disease) including orthostatic hypotension, pigment changes, and decreased axillary or pubic hair should be sought.
signs of hyperprolactinaemia
Signs may include lactation on expression and, if there is an expanding pituitary prolactinoma, bitemporal hemianopia.
signs of genetic syndromes
Include short stature, webbed neck, cubitus valgus (increased carrying angle of arms), and lack of sexual development at puberty (Turner syndrome).
Risk factors
strong
family history of POF
In patients with premature menopause, 37.5% reported a family history of early menopause.[8]
exposure to chemotherapy or radiation
Varies based on the agent used, the dose, the duration of exposure, and the age at time of exposure. Increased risk with advancing age: for example, <20% in women age <30 years versus the majority of women age >40 years.[11] Risk for chemotherapy is highest with alkylating agents, with the risk being 9 times higher with these therapies.[12][13]
autoimmune disease
Approximately 30% to 40% of women with POF and normal karyotypes will be found to have an autoimmune disease.[14][15]
The most commonly reported autoimmune disease associated with POF is thyroid disease, and 20% will demonstrate antithyroid antibodies.[15]
Non-endocrine autoimmune diseases that have been associated with POF include idiopathic thrombocytopenic purpura, vitiligo, alopecia, autoimmune haemolytic anaemia, pernicious anaemia, systemic lupus erythematosus, rheumatoid arthritis, Crohn's disease, and Sjogren syndrome.
family history of fragile X syndrome
galactosaemia
Patients with galactosaemia have an enzyme deficiency associated with mental retardation, cataracts, and hepatorenal damage. A galactose-restricted diet can help minimise these consequences, although most affected females develop POF.[18]
weak
hysterectomy
Women who have undergone hysterectomy without removal of the ovaries undergo menopause an average of 4 years earlier than women with spontaneous menopause.[19] The presumed mechanisms for this observation are decreased blood supply to the ovary or severe inflammation affecting the ovary.
uterine artery embolisation
Uterine artery embolisation has been associated with POF by decreasing blood flow to the ovary.[20]
smoking
Women who smoke have nearly twice the risk of developing POF.[21]
lower socioeconomic status, higher education level, nulliparity
One population-based study found weak associations with these characteristics, although no mechanisms have been determined.[22]
presence of specific genetic variants
Studies have begun to identify genetic variants that can be used to determine which women may be at risk of early menopause.[23] This may allow at-risk women to plan to conceive earlier, or to cryopreserve oocytes.
ovarian surgery
Women who have undergone ovarian surgery, for example for endometriosis or other ovarian cystic disorders, are at increased risk of POF due to follicle depletion following surgical damage.
