Uterine fibroids and fertility
Common, usually harmless to fertility — except when location says otherwise.

What it is
Fibroids are benign muscular growths in the uterus and they are very common. Most do not affect fertility. What matters is location rather than presence or size alone: fibroids that distort the uterine cavity, particularly submucosal ones, are associated with reduced implantation and higher miscarriage rates, while fibroids on the outer surface generally are not. This is why a careful assessment of the cavity, rather than a count of fibroids, drives the decision to operate.

Signs people notice
Having one of these does not mean you have this condition, and having none does not rule it out.
- Often none
- Heavy or prolonged menstrual bleeding
- Pelvic pressure, bloating, or urinary frequency
- Pain during sex
- Difficulty conceiving or recurrent miscarriage, where the cavity is affected
How it is diagnosed
Pelvic ultrasound, with saline sonohysterogram or hysteroscopy to define the relationship to the cavity, and MRI for surgical planning in complex cases.
Treatment paths that usually follow
- Observation, which is appropriate for most fibroids that do not distort the cavity
- Hysteroscopic removal of submucosal fibroids, usually a day procedure with a good fertility outlook
- Myomectomy for larger intramural fibroids distorting the cavity, weighed against recovery time and uterine scarring
- Proceeding directly to IVF where fibroids are not the limiting factor
- Avoiding procedures such as uterine artery embolization when future pregnancy is intended
Each of these is explained in the treatment library. Which one is right depends on your age, your history, and your own priorities.
What to ask your clinician
- Does any fibroid distort my uterine cavity?
- Would removing it measurably improve my chance, or just delay treatment?
- How long would I need to wait after surgery before trying or transferring?
- Would surgery affect how I could deliver?
