What is Asherman’s syndrome?

Asherman’s syndrome is an acquired condition (one you are not born with) that refers to having scar tissue in the uterus or in the cervix (the opening to the uterus). This scar tissue makes the walls of these organs stick together and reduces the size of the uterus. Asherman’s syndrome is also known as intrauterine synechiae or uterine synechiae. Synechiae means adhesions. Asherman’s syndrome is also called intrauterine adhesions (IUA).

Asherman’s syndrome

How common is Asherman’s syndrome?

Asherman’s syndrome is considered a rare disease. It is hard to say how often it actually occurs because it is not always diagnosed. Some research estimates that IUA happen in nearly 20% of women who have had dilation and curettage (D&C) after pregnancy complications.

What are the symptoms of Asherman’s syndrome?

  • Having very light periods (hypomenorrhea)
  • Having no periods (amenorrhea)
  • Having severe cramping or pain
  • Being unable to get or stay pregnant

Some women have no symptoms, and some women have normal periods.

What causes Asherman’s syndrome?

  • Scar tissue from uterine surgery like dilation and curettage (D&C). (This is the cause of more than 90% of IUA.)
  • Scar tissue after a Cesarean section or from sutures used to stop hemorrhages
  • Endometriosis
  • Infections of the reproductive organs
  • Radiation treatment
