Amenorrhoea (Absent Periods)
Fertility General Gynaecology 

Amenorrhea refers to the absence of menstrual periods in females. Amenorrhea is an abnormal event in a female’s life except during childhood, pregnancy, breastfeeding and menopause.

Amenorrhea can either be primary or secondary.

Primary Amenorrhea

Primary amenorrhoea is said to occur when periods have not started by the age of 15 or within three to five years of attaining puberty (development of secondary sexual characteristics such as developing breast and pubic hair) or, the failure of onset of puberty (no signs of secondary sexual characteristics such as developing breasts and pubic hair) by the age of 13. 

Secondary Amenorrhea

One is said to have secondary amenorrhoea when periods have stopped for about three months or more after normal puberty and menstruation.

Causes of Amenorrhea

Depending on the type of amenorrhea, the causes of amenorrhea are divided into two.

Causes of primary amenorrhoea

Causes of primary amenorrhea include:

  • Turner’s syndrome is the most common cause of primary amenorrhea.
  • Genetic or chromosomal abnormality with the ovaries.
  • Pituitary gland disorders
  • Problems with the hypothalamus 
  • Structural abnormalities with the reproductive organs such as the ovaries, uterus, cervix, and vagina.
