    RESEARCH HIGHLIGHTS
    A majority of NZ adolescents carry a cellphone switched-on in a pocket > 6 hrs/day More than two in five regularly send texts from within a side pocket A fifth carry one >10 hrs/day and use it in-pocket Research suggests this may impair future fertility and/or reproductive integrity

    ABSTRACT

    We explored school cellphone rules and adolescent exposure to cellphone microwave emissions during school with a census and survey respectively. The data were used to assess health and policy implications through a review of papers assessing reproductive bio-effects after exposure to cellphone emissions, this being most relevant to students’ exposure.
    All schools banned private use of cellphones in class. However, 43% of student participants admitted breaking this rule. A high-exposure group of risk-takers was identified for whom prohibited in-school use was positively associated with high texting rates, carrying the phone switched-on >10 hours/day, and in-pocket use.
    The fertility literature is inconclusive, but increasingly points towards significant time- and dose- dependent deleterious effects from cellphone exposure on sperm. Genotoxic effects have been demonstrated from „non-thermal‟ exposures, but not consistently. There is sufficient evidence and expert opinion to warrant an enforced school policy removing cellphones from students during the day.
