Pilot Evaluation of Patient-Assisted Motorized Transvaginal Ultrasound Acquisition During Ovarian Stimulation Monitoring

Patient-assisted motorized transvaginal ultrasound during ovarian stimulation monitoring produced evaluable datasets in 94.7% of 19 acquisitions in 10 women, with no adverse events.

• Why it matters: Standard transvaginal ultrasound requires clinic time and operator effort; a supervised approach that patients can assist with could improve feasibility while maintaining safety.
• What they did: In this prospective first-in-human pilot, participants inserted and stabilized the probe while a predefined motorized rotational sequence was run under clinical supervision, yielding 19 investigational acquisitions.
• The result: Evaluable imaging occurred in 18/19 (94.7%), bilateral ovarian visualization in 16/18 (88.9%), follicle counts ≥14 mm correlated with mature oocyte recovery (rho=0.83), and endometrial thickness agreement was 14/15 (93%).
