Sovereign — Plant-Based Male Contraception
Sovereign is a plant-based, non-hormonal, fully reversible contraceptive for men developed by Sovereign Life Sciences.
Meet the Founder
Chris Shewchuk has spent 15 years immersed in embodied and relational practices. Experiences with plant medicine opened an unexpected door, and when he encountered Justicia gendarussa and its traditional use as a male contraceptive, everything converged. We have co-evolved with plants and ecosystems for time unknown, and Chris believes this plant has a specific gift and intention for humanity — to support deep trust between partners, and thriving intimate relationships. Sovereign is built to bring that gift forward with integrity.
The Opportunity
The global contraceptive market sits around $30B today and is projected to roughly double by the mid-2030s. Male contraception represents less than 10% — almost entirely condoms and vasectomy. There is no approved oral male contraceptive anywhere in the world. Meanwhile, the global dietary supplement market (~$210B) is on track to more than double within the decade, with the botanicals segment growing at roughly 9% annually. A natural male contraceptive sits at the intersection of these two trends. First mover in natural male contraception — a new category. Now raising: Phase 1 bridge funding of $26.5K CAD to complete validation testing and support project operations. Convertible promissory notes at a 50% discount with a $2M valuation cap.
The Nimboran People
The contraceptive use of Justicia gendarussa originates with the Nimboran people of Indonesian Papua. Indigenous Papuans face an escalating military occupation, with over 105,000 civilians displaced as of early 2026. Sovereign intends to pursue partnership, revenue sharing, and cultural preservation with Nimboran and other indigenous communities. International visibility and partnership can also serve as a form of protection for communities under threat.
The Plant: Justicia gendarussa
Justicia gendarussa is a tropical shrub used by the Nimboran people of Indonesian Papua for generations as a natural male contraceptive. The active compounds interfere with sperm's ability to penetrate the egg — without affecting sperm count, hormones, or libido. Indonesian university studies documented 99.5% efficacy with full reversibility.
The Science
Sovereign's founder has completed two exploratory proteomics studies. Study 1 identified two proteins matching those reported absent in the Indonesian Phase 2 clinical data. Study 2, a longitudinal study with escalating doses, repeated sampling, and a washout period, is now complete. Results expected June/July 2026 will confirm or refute the Indonesian data and provide a meaningful basis to develop the first protocol for men.
The Strategy
Sovereign operates two integrated arms: Sovereign R&D drives the science, and Eros & Soul (erosandsoul.com) is an ecosystem of support for thriving intimate relationships. Phase 1: completing proteomics validation, HPLC standardisation, lab partnerships, and establishing E&S coaching services. Phase 2: men's health supplement with compliant claims, Nimboran fieldwork, and development of the E&S online platform with additional providers and resources. Phase 3: clinical trials toward a validated contraceptive claim. Long-term: phytopharmaceutical and pharmaceutical pathways explored to determine if ethical production is possible. Premium pricing funds global access.
