The Technology

The Calla Campaign was born out of a medical device, the Callascope, which aims to increase access to reproductive healthcare. Developed by the Center for Global Women’s Health Technologies at Duke University, the Callascope employs low-light imaging technology to visualize the inner vagina and cervix. The Callascope is designed by women, and enables people with a cervix to comfortably explore their own inner reproductive anatomy in the privacy of their homes.

The Callascope is low-cost, portable, and connects to a mobile device or a tablet, replacing the traditional speculum exam that uses an expensive colposcope which acts as a barrier to healthcare in low resourced settings. Moreover, the Callascope employs a decision-making algorithm that can detect precancerous symptoms in the cervix. Through technological innovation, the Callascope disrupts barriers to healthcare and offers an alternative for people with a cervix to take charge of their own health.

Below, you will find a video of a woman imaging her own cervix.

Testimonials from individuals 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”.

We would love to hear your thoughts about the Callascope. If you are interested in participating in our next study to try out the Callascope device and/or receive updates on events please sign-up below.

The Callascope inserter tip was designed by two biomedical engineering students Mercy Asiedu and Julia Agudogo, and was developed from the Pocket Colposcope visualization technology. While the imaging technology was developed with the barriers to resources in mind, the Callascope inserter tip was designed for the comfort of the body in mind, receiving feedback from women’s groups throughout the process. In this way, the entire team at the Center for Global Women’s Health Technologies works collaboratively and with the broader community to design the best tools for healthcare.
