Primary amenorrhoea (menstrual periods fail to appear at puberty) may be caused by absence of the uterus or ovaries (e.g. Turner’s syndrome) or by a hormonal imbalance.

  • disorders of the hypothalamus
  • deficiency of ovarian, pituitary, or thyroid hormones
  • mental disturbance
  • depression
  • anorexia nervosa
  • or by a major change of surroundings or circumstances.

Effect (Symptoms)

The absence or stopping of the menstrual periods.
(It is normal for the periods to be absent before puberty, during pregnancy and milk secretion, and after the end of the reproductive period.)
