Abstract

Antimicrobial peptides (AMPs) have emerged as promising candidates for dual-action contraceptive agents, offering both spermicidal and antimicrobial properties. This perspective explores the potential of AMPs in developing novel contraceptive technologies, focusing on their application in condom coatings and vaginal formulations. AMPs exert their effects through membrane disruption mechanisms, targeting both microbial pathogens and sperm cells. Their broad-spectrum activity against various microorganisms, coupled with spermicidal effects, makes them ideal for multipurpose prevention technologies. The incorporation of AMPs into condoms could enhance barrier protection, while vaginal applications offer non-hormonal, on-demand contraceptive options. However, challenges, such as potential vaginal irritation, microbiome disruption, and the need for long-term safety studies, must be addressed. Future research should focus on optimizing AMP selectivity, developing stable formulations, and conducting comprehensive efficacy and safety trials. The dual-action nature of AMPs aligns with the growing demand for integrated approaches to sexual and reproductive health, potentially revolutionizing contraception and STI prevention. By addressing current challenges and leveraging the unique properties of AMPs, researchers can develop a new generation of contraceptive products that offer improved efficacy, safety, and user acceptability.
