Sovereign Life Sciences
Reproductive sovereignty, for men.
A non-hormonal, reversible male contraceptive in development, from a plant used for generations.
For decades, contraception has been a woman's job.
Men have two options — condoms and vasectomy — and little in between. Sovereign is developing a third: a daily, plant-based option that leaves hormones untouched and reverses when a man stops taking it.
Our work
Traditional knowledge. Modern evidence.
Justicia gendarussa
A tropical shrub used by the Nimboran people of Indonesian Papua for over seven generations, documented through decades of Indonesian research.
Where the work stands
Two exploratory studies on seminal-fluid biomarkers, results pending. Proof-of-concept testing is next, and we're seeking partnership with the original Indonesian research team.
Two markets, converging
A natural male contraceptive sits where the growing contraceptive and botanical-supplement markets cross. No approved oral male contraceptive exists anywhere. Pre-seed investment open now.
The next level of responsible development
From proof of concept to product, built on partnership with the Nimboran, respect for ecosystems and ethnomedicine, and access for as many people as possible.
Held in trust
Benefit-sharing with source communities, developed with their help — and built into our DNA from the start.
Mission & team
Who we are, what we hold to, and the people behind the work.
At a glance
Detailed methodology and study data available under NDA.
The longer arc
It starts with male contraception. But that's just the beginning.
Sovereign's longer arc is a new kind of medicine, and a new way of doing business — rooted in plants and the people who steward them, developed through partnership rather than extraction, and made accessible to as many people as possible, including those who need it most and can least afford it. Medicine that generates health at every scale: in bodies, relationships, families, communities, and the living systems we all depend on.
Join the movement
A new kind of business for a new kind of world.
Sovereign is built for scientific rigour, economic success, and the health of families, communities, cultures, and ecosystems. Whether you invest, advise, lend a skill, or simply follow along and share the work, there's a place here for you.
