The Technology

With the intention of empowering women to have autonomy over their bodies and have more access to reproductive care, the Center for Global Women’s Health Technologies at Duke University has developed a novel tool, the Callascope, for self-imaging of the inner vagina and the cervix. The Callascope, designed by women for women, enables for the first time, a woman to comfortably and easily explore her own inner reproductive anatomy in the privacy of her home.

The Callascope was invented by two BME students Mercy Asiedu and Julia Agudogo. Mercy is in the final year of her doctoral studies in Biomedical Engineering and Julia is a first-year medical student who received her B.S. in Biomedical Engineering at Duke.

The Callascope has been used by women in the comfort of their own homes to explore their reproductive anatomies. A video of a woman imaging her own cervix is showing below.

Testimonials from women who have used the Callascope:

It was an empowering and intimate experience with myself.

“I really liked this device. I thought it was really easy to use. I thought the instructions were really straight-forward. I think it is a really cool idea”

“I think it’s less intimidating and it’s friendlier.” “I think this is comparable to a tampon

“The new Callascope was much more comfortable and easier. It’s never enjoyable going to an OBGYN, however, this is much more welcoming than the old speculum.”

“You know, it’s just so cool that there is a camera that shows you so that you can see for yourself whatever someone else is seeing during a pelvic exam”.

“The speculum is cold and very just, mechanical. Not natural, at all. It almost looks like something you would see in a horror movie. You know when they show the torture chamber with all the weird stuff hanging. This (the speculum) could be right in there with all the rest of the torture instruments”.

Recently, the team has won the prestigious Duke’s DGHI Innovation Jam! A shark tank style fastpitch presentation to acquire long-term investment based on the quality and potential of the product. The student-led pitch team was a standout in the competition.
