Posted by dkwinter

Note: menopausal transition before age 40 is premature ovarian failure

 

Early menopausal transition

  • 7 to 60 day difference consecutive cycle length
  • duration variable, usually starts about 4 years prior to FMP
  • variable increase in FSH
  • vasomotor symptoms not characteristic

 

Late menopausal transition

  • >= 60 day intervals of amenorrhea
  • duration 1-3 years
  • FSH > 25 IU/L on cycle days 2 to 5
  • Vasomotor symptoms likely

 

Postmenopause

  • amenorrhea
  • duration of remaining lifespan
  • variable increase in FSH, which then stabilizes
  • vasomotor symptoms more likely
  • late postmenopause period (6 years after FMP) characterized by increasing symptoms of urogenital atrophy
