Fibroids are non-cancerous growths made from muscle and fibrous tissue in or around the uterus. Many are found during a scan and cause no difficulty with conception. Whether a fibroid matters for fertility depends particularly on its location and whether it changes the space inside the uterus.
Finding a fibroid does not prove it is the reason pregnancy has not happened. A doctor needs to consider symptoms, the scan and the rest of the fertility assessment. This helps avoid an operation for a finding that may not be affecting the chance of pregnancy.
Why location matters
Submucosal fibroids grow towards the uterine cavity and may distort its shape. Intramural fibroids are within the muscular wall, while subserosal fibroids grow towards the outside. These names describe different positions rather than different levels of danger.
Fibroids that distort the cavity are more likely to affect implantation or pregnancy than those growing mainly on the outside. For fibroids within the wall that do not alter the cavity, the effect can be less clear. Size, number and the individual treatment history help guide the discussion.
Symptoms that need attention
Fibroids can cause heavy or prolonged periods, pelvic pressure, pain or frequent urination. Heavy bleeding may lead to iron deficiency or anaemia, which deserves treatment whether or not fertility care is planned. Some people have no symptoms at all.
Tell the doctor if bleeding affects daily life or if you feel unusually tired, breathless or faint. Severe bleeding with faintness or marked weakness needs urgent assessment. A symptom should not be dismissed simply because fibroids are common or described as benign.
Understanding the scan
Ultrasound often identifies fibroids and provides their measurements and location. If it is unclear whether the uterine cavity is affected, further imaging or a hysteroscopy may be suggested. Hysteroscopy uses a small camera to examine inside the uterus and is not needed for every fibroid.
Ask the doctor to explain which finding, if any, could affect your fertility plan. A report listing several measurements can look alarming without that context. Keep earlier scans because changes over time may also be relevant to the decision.
Does a fibroid need removing?
Many fibroids can be monitored without surgery. Removal may be considered when symptoms are significant or when a fibroid affecting the cavity is likely to interfere with conception or treatment. The expected benefit should be explained before deciding on an operation.
Myomectomy removes fibroids while retaining the uterus, but it still carries risks such as bleeding and scarring. Recovery time, the effect on future pregnancy and whether a fibroid may recur also matter. Your doctor should explain how long to wait before trying after the particular procedure planned.
Choosing treatment when you want a baby
Some treatments used for heavy bleeding or fibroid symptoms are not suitable when future pregnancy is a priority. The effect of certain procedures on fertility may be uncertain, and removal of the uterus ends the possibility of carrying a pregnancy. Make your reproductive plans explicit before agreeing to treatment.
IVF does not automatically require every fibroid to be removed first. A fertility doctor and gynaecologist can consider the uterine cavity, symptoms, age and other results together. The next step should address a clear concern rather than treating the presence of any fibroid as a reason to delay trying indefinitely.
