The Pursuit

Not settling for anything less than revolutionary

1960 was a defining moment in history. The introduction of oral hormonal birth control gave women easy control over their reproductive decisions and ushered in historical achievements in gender equality. However, as we start documenting the side-effects that hormonal birth control methods cause, it is clear that we can do better.

Our goal is to uphold the radical ideals that fueled the initial birth control movement. No longer should we accept the side effects that have become normalized by hormonal birth control. Nor the inconvenience of existing alternatives. OUI is an attempt at embracing innovation to expand freedom for women. In this pursuit, we should not settle for anything less than revolutionary.

We are proud to announce...

Zero Compromise Contraception

OUI is a vaginal capsule that after insertion rapidly dissolves and releases the formulation. It is targeted to provide effective birth control a minute after insertion and for up to 1 day without the use of any hormones.

How does OUI work?

OUI makes cervical mucus temporarily impenetrable to sperm. The barrier is established by a molecule that strongly interacts with cervical mucus and thereby reinforce the mucus to make it impretratable for sperm cells. As the sperm cells are unable to enter the cervix they are maintained in the vaginal cavity where low pH environment of the vagina deactivates them.

The Appeal of Mucus Engineering

The path towards zero side-effects

The research that led to the concept of OUI stems from the developing research area of mucus engineering. We view the mucus gel that covers our mucosa and protects us from infections as a material that can be engineering at a molecular level. This approach has appeared in various forms over the past few years, e.g. to restore lubrication, hydration, and to modulate the microbiome. What makes the mucus engineering approach appealing in a birth control application is that the mucus is modified via topical treatment. This means that the formulation only interacts with the mucus layer on top of the mucosa and is not acting like a drug, which is ideal when the goal is to minimize side-effects.
