Materna Medical Launches Groundbreaking Virtual Clinical Trial Evaluating Treatment of Vaginismus Symptoms Using the Milli™ Vaginal Dilator

Seeking Participants to Advance Research on Vaginismus and Related Painful Sex

June 06, 2024 [Mountain View, Calif.] — Materna Medical, Inc., a leading innovator in women’s
pelvic health solutions, is proud to announce the launch of a new clinical study, Prospective On
Market Patient-reported Outcomes for Milli™ Vaginal Dilator (POMPOM). This groundbreaking
clinical investigation aims to gather valuable data on the effectiveness of the Milli Vaginal Dilator to
help relieve the symptoms of vaginismus and related painful intercourse.

Millions of People Are Affected by Vaginismus

Vaginismus is a common yet underreported condition affecting between 5-17% of people assigned
female at birth. The condition is characterized by involuntary muscle contractions of the vaginal
wall, making sexual penetration difficult or impossible. Many suffer in silence because they are not
aware that vaginismus is a treatable medical condition and don’t realize that help is available.
“Treatments for male sexual dysfunction are well-funded and well-researched, but there is a critical
lack of research on medical interventions for vaginismus and related painful sex,” says Tracy
MacNeal, CEO of Materna Medical. “The POMPOM study will generate essential data on the Milli
Vaginal Dilator, a discrete, convenient, at-home solution for managing this common condition.”

Materna’s Solution for Vaginismus

The Milli Vaginal Dilator, our first product, addresses this condition to support patients suffering
from vaginismus and related painful sex. In 2019, the Milli device launched as a wellness trainer
and, in 2023, received FDA clearance* to sell over the counter, enabling streamlined access to
people suffering from vaginismus.

Seeking Participants to Drive Research Forward

Materna Medical invites people experiencing vaginismus symptoms to participate in the POMPOM
study (ClinicalTrials.gov NCT06397885). The virtual, secure, confidential format allows convenient
participation and makes research accessible to a broader population.

“By participating in this study, Milli users will help clinicians learn more about how to help women
with vaginismus and associated painful intercourse,” said Sheryl Kingsberg, Ph.D., Professor,
Departments of Reproductive Biology, Psychiatry, and Urology, Case Western Reserve University
School of Medicine and POMPOM’s Principal Investigator. “Treatment for this debilitating problem
remains underutilized though technological advances in pharmacology and devices, like the Milli
Vaginal Dilator, may help in alleviating the painful symptoms associated with vaginismus.”

The POMPOM study builds on the initial Milli Vaginal Dilator data previously published in the April
2021 issue of Sexual Medicine Reviews, Vaginal Dilators: Issues and Answers.¹
