Objective:
To determine the effect on ovarian reserve of ultrasound-guided high-intensity focused ultrasound (HIFU) in the treatment of uterine fibroids.
Methods:
We performed a mid-study analysis of markers of ovarian reserve using data from a prospective cohort study evaluating the safety of ultrasound-guided HIFU for uterine fibroids. Blood samples obtained from 12 women with uterine fibroids less than one week before treatment were used for measurement of serum anti-Mullerian hormone (AMH), and this testing was repeated in the first, third, sixth, and 12th month after ultrasound-guided HIFU treatment.
Results:
Fourteen fibroids from 12 patients were treated using ultrasound-guided HIFU. The median baseline fibroid volume was 101.2 cm(3) (range 18.5 to 349.2 cm(3)). The median treatment time was 140.5 minutes (46 to 192 minutes), and median sonication time was 1449 seconds (range 541 to 2445 seconds). The median energy delivered was 575 521.5 joules (range 216 400 to 898 273 joules). The median AMH levels (ng/mL) before treatment and at one, three, six, and 12 months after treatment were 0.3 (range 0.01 to 1.94), 0.47 (0.01 to 1.43), 0.205 (0.01 to 1.81), 0.26 (0 to 2.37), and 0.06 (0.02 to 1.04), respectively. There was no significant difference between the AMH levels before and at any time after treatment. No patient became amenorrheic or reported symptoms suggestive of menopause after treatment.
Conclusion:
Our preliminary experience suggests that ovarian reserve does not seem to be affected by ultrasound-guided HIFU in the treatment of uterine fibroids.

Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
