| Summary: | Abstract Background Outbreaks of mosquito-borne viral illnesses commonly occur after storms. As storms are predicted to worsen in intensity and frequency, mosquito-borne viruses, including the Zika virus are expected to spread, and with devastating consequences. While the disease is self-limited, pregnant women who contract Zika can transmit the virus to their fetuses, causing neurodevelopmental abnormalities, including microcephaly. An overlooked vector of the Zika virus, however, is men whose semen can transmit the virus at the time of sexual intercourse. Current recommendations for preventing the sexual transmission of Zika are inadequate and need to emphasize male reproductive responsibility, via expanding services for men’s family planning and developing novel male contraceptives. Main body To prevent the sexual transmission of Zika, the World Health Organization recommends that couples use condoms or abstain from sexual activity for at least 6 months when traveling in Zika-infected areas. Strict adherence to these recommendations is neither practical nor adequate to address Zika’s sexual transmission. As up to 13% of couples who use condoms experience unintended pregnancy, semen and consequent viral exposure is imminent. The use of contraception beyond just barrier methods is essential. However, the burden of contraception largely falls upon women and efforts to prevent vertical transmission are often aimed at educating women, when the outcome is equally undesirable among their male partners. These short-comings highlight the lack of attention to men’s options for family planning. Educating men about the full range of contraceptive options, correcting misconceptions about the efficacy of withdrawal and barrier contraceptive methods, increasing access to vasectomy, and developing novel male contraceptive options would allow shared responsibility for the prevention of unintended pregnancy and Zika-related morbidity. Conclusion Gaps in recommendations to prevent the sexual transmission of Zika provide an opportunity to develop men’s family planning initiatives and the range of accessible contraceptives to men.
