title: Serum anti-müllerian hormone level is not altered in women using hormonal contraceptives.
abstract: BACKGROUND
  Anti-müllerian hormone (AMH) is secreted from granulosa cells of antral follicles into the circulation of adult women and hence could serve as an ovarian function test. This would be of value to hormonal contraceptive users if its serum level is unaffected by the use of hormonal contraceptives.
  
  
  METHODS
  We prospectively recruited 95 women using combined oral contraceptive (n=23), combined injectable contraceptive (n=23), progestogen-only pills (n=9), progestogen-only injectable (n=20) and levonorgestrel intrauterine system (n=20), and measured their serum AMH concentration before and 3-4 months after treatment.
  
  
  RESULTS
  No significant difference in pre- and post-treatment serum AMH level was evident in all the treatment groups studied.
  
  
  CONCLUSIONS
  Being unaffected by hormonal contraceptives, serum AMH measurement is potentially a useful clinical test in hormonal contraceptive users for the differential diagnosis of anovulatory disorders and determination of menopause.
