Purpose: Nearly half of all pregnancies worldwide are unintended. Furthermore, male contraceptives are limited to condoms and vasectomy, which do not provide adequate variety in characteristics to meet the needs of all users.
Male Contraceptive Initiative (MCI), a US-based 501(c)3 nonprofit, is a funding agency and advocate for safe, effective, and reversible contraceptive solutions for sperm-producing people.
Background: MCI's Focus Grants are designed as a strategic signal-setting mechanism to create deliberate incentives in areas where progress is unlikely without targeted support. Many of the most important advances in non-hormonal male contraception will not occur organically, particularly given the predominantly academic landscape and limited pharmaceutical engagement. Focus Grants concentrate resources where strategic investment can create disproportionate impact.
Focus Area: Targeted Protein Degradation
Proteolysis targeting chimeras (PROTACs) and related targeted protein degradation approaches (e.g, molecular glues) represent a promising but underexplored modality for male contraception. These molecules are typically bifunctional: one region binds the target protein, while a second region connected by a linker serves as an E3 ubiquitin ligase recruiting element (E3RE) that binds to an E3 ligase, thereby initiating the degradative process.
Contraceptives leveraging this mechanism of action have the potential to be both fast-acting and possess a long duration of action, addressing key unmet needs in the male contraceptive product landscape, and offering a potential solution to the problem of ‘washout’ in the female reproductive tract for inhibitors targeting mature sperm function. However, targeted degradation remains an emerging field even in common therapeutic areas. Knowledge of the distribution, localization, and functional relevance of testis- and sperm-expressed E3 ligases is limited, and there is a major unmet need for new E3RE chemotypes beyond commonly used ligands (e.g., cereblon-based systems), particularly in contraceptive applications where selectivity, safety, and tolerability are paramount.
Award Budget
$150,000 - $300,000 of total costs allowed depending on project scope.
👉 Off-topic reproductive or general fertility research → low success probability
👉 Key question:
“Will this lead to a viable male contraceptive method?”
👉 Innovation must be practical and scalable
👉 Proposals that clearly address this gap score highly
👉 Overly ambitious or vague proposals are commonly rejected
👉 Evaluation includes:
👉 Applicants engaged in the field have an advantage
👉 Broader impact strengthens applications
👉 Cross-disciplinary innovation improves competitiveness
👉 Clear next-step pathway is important
Highest impact factors:
Moderate predictors:
4. Unmet need relevance
5. Feasibility
6. Early-career development
Supporting factors:
7. Community engagement
8. Interdisciplinary approach
9. Global health relevance
Compared to NIH or general reproductive funders:
👉 Winning formula:
Non-hormonal idea + clear path to real contraceptive + feasible pilot study
✔️ What wins:
❌ What struggles:
This application is open to global academic institutions, for-profit organizations, and other entities. Any individual(s) with the skills, knowledge, and internal or external resources necessary to carry out the proposed research as a Principal Investigator (PI) is invited to submit an application through their institution.
Eligibility is explicitly limited to projects centered at the intersection of targeted protein degradation and male contraception. Applications must clearly address one or more of the three strategic areas outlined above.
Applicants may submit more than one application, provided that each application is scientifically distinct. Current MCI grantees are eligible to apply. MCI values representation and diversity in the scientific community. Applications from women, people of color, the LGBTQIA community, and other historically marginalized groups are encouraged.
Projects that are not responsive to this announcement include: General PROTAC chemistry or E3 ligase biology without clear application to male contraception. Projects focused on targets not relevant to male reproductive biology. Approaches developing contraceptives intended to be delivered to female users. Approaches that permanently inhibit fertility or cause sterility. Approaches involving administration of steroid hormones to manipulate the HPG axis. Approaches that induce active immunity. Applications focused on molecular targets for which there is no human ortholog. Projects that duplicate or highly overlap with other funded work.
Applicants should note that MCI also offers other grant programs geared towards larger development-focused projects, small exploratory projects, and fellowships for pre-doctoral and post-doctoral training. Proposals better suited to these mechanisms may be redirected during review. Applicants with questions regarding eligibility or appropriate mechanism are encouraged to contact MCI in advance of application submission.
