Helen Elizabeth O'Connell AO (born 3 April 1962)[1] is an Australian professor of urology and a pioneer in the anatomical study of the clitoris.

O'Connell's aim was to improve knowledge of female pelvic anatomy, including the genitourinary tract with the reproductive organs, through insights from surgery.

[citation needed] Her clinical and research focus is on the surgical treatment of lower urinary tract problems, particularly incontinence and bladder sphincter obstruction.

Multiplanar imaging of clitoral anatomy using magnetic resonance imaging in the living state supplemented the dissection material and showed that the erectile vestibular bulbs are a part of the clitoris, and that the female urethra and vagina, although not erectile in character, are closely related structures that form a tissue cluster with the clitoris that is the site of female sexual function and orgasm.

[6] In 2010, O'Connell succeeded for the first time in depicting a stimulated clitoris in a 3D image and showing its more than 15,000 nerve endings in the pelvic area.
