Is pregnancy possible after HIFU?
Yes — pregnancies and healthy births after HIFU are reported in the literature, and the method aims to preserve the uterus and its tissue integrity. The honest answer, though, is this: "the uterus is preserved" and "your chance of pregnancy is assured" are not the same statement, and comparative data on pregnancy after HIFU are conflicting. If you plan a pregnancy, method choice should be made with that uncertainty discussed openly.
What "uterus-preserving" means — and does not mean
With HIFU the uterus stays in place and no surgical incision is made in its wall — a real and important feature. Fertility, however, depends on many components: the health of the uterine lining, the structure of the wall, and the effect of the fibroid itself. That is why we use the phrase "uterus-preserving method" and deliberately avoid claiming assured fertility.
The evidence: two meta-analyses, two directions
A 2024 meta-analysis found lower pregnancy and live-birth rates after HIFU compared with myomectomy.

A 2023 meta-analysis, by contrast, reported similar live-birth rates in pregnancies after embolisation, HIFU and transcervical ablation, with only small differences in some endpoints.
Read together, the meaning is that the evidence has not matured. Study populations, devices and selection criteria differ — a definitive sentence cannot honestly be written.

Guideline positions support this cautious frame: NICE describes the effect of focused ultrasound on subsequent pregnancy as uncertain, and guidelines maintain surgery’s established position when fertility is the priority.

How to think about it if you plan a pregnancy
- First clarify whether your fibroid actually affects fertility (location is decisive).
- Compare the established option — myomectomy — with HIFU over your own case.
- If HIFU is chosen, protection of the uterine lining in the ablation plan deserves its own discussion.
- Decide together with your gynaecologist and, where needed, reproductive medicine input.
The purpose of this page is not to steer you toward a method; it is to make the uncertainty itself an informed part of your decision.
