Fibroids and your fertility


Uterine fibroids are non-cancerous growths that develop in the uterus and are made up of muscle and fibrous tissue. They are the commonest benign pelvic tumour in women affecting 20% to 50% of women of reproductive age.

It is not known what causes fibroids, but there is evidence that genetics and prolonged exposure to oestrogen may increase your risk of developing fibroids. Fibroids regress after the menopause secondary to the loss of hormone stimulation. Fibroids are more commonly seen with increasing age and occur with increased frequency in black and Asian ethnicities.

Fibroids vary in size and can occur as single fibroids or multiple ones.

Common symptoms of fibroids.

Uterine fibroids often cause no symptoms. They can be discovered by chance during a pelvic examination, although only around one-third of fibroids are large enough to be detected.

For those who experience symptoms, these depend on the size, location and number of fibroids. The most common symptoms are:

  • Painful, heavy or prolonged menstrual periods
  • Pelvic pressure or pain
  • Pressure on the bladder causing frequent urination or difficulty emptying the bladder
  • Pressure on the rectum causing constipation
  • Back or leg pain

It is essential to get medical help if you experience severe menstrual bleeding or sharp, sudden pelvic pain.

Types of fibroids.

Fibroids are classified by their location. These are:

  • Intramural fibroids – within the uterine wall
    Submucosal fibroids – project into the uterine cavity
    Subserosal fibroids – expand outside of the uterine wall

Diagnosing fibroids.

It is essential to seek a confirmed diagnosis by an expert if you are experiencing any symptoms of growing or large uterine fibroids. Consultant gynaecologist Miss Amanda Tozer at Aria Fertility is an expert in women’s health and has a vast knowledge of menstrual disorders, including fibroids. She will carry out a physical pelvic exam and will carry out a complete medical history check. A confirmed diagnosis may require imaging (MRI or ultrasound) or a hysteroscopy.

Treating fibroids.

If your fibroids are causing significant symptoms, Miss Amanda Tozer can advise women on a range of tailored treatment options, including lifestyle changes, medications, hormone treatments and, if required, minimally invasive gynaecological surgery.

Can fibroids affect pregnancy?

Fibroids should not interfere with getting pregnant. However, certain fibroids, particularly Submucosal fibroids, which invade the cavity of the uterus, can cause pregnancy complications. Adverse effects that fibroids can have on pregnancy include:

  • Increased risk of miscarriage
  • Abnormal attachment of the placenta
  • Increased likelihood of caesarean section
  • Postpartum haemorrhage
