Paternal exposure to occupational electromagnetic radiation and sex ratio of the offspring: a meta-analysis / 中华男科学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the association between paternal exposure to occupational electromagnetic radiation and the sex ratio of the offspring.</p><p><b>METHODS</b>We searched various databases, including PubMed, Embase, Cochrane Library, OVID, Bioscience Information Service (BIOSIS), China National Knowledge Infrastructure, VIP Database for Chinese Technical Periodicals and Wanfang Database, for the literature relevant to the association of paternal exposure to occupational electromagnetic radiation with the sex ratio of the offspring. We conducted a meta-analysis on their correlation using Stata 11.0.</p><p><b>RESULTS</b>There was no statistically significant difference in the sex ratio between the offspring with paternal exposure to occupational electromagnetic radiation and those without (pooled OR = 1.00 [95% CI 0.95 -1.05], P = 0.875). Subgroup analysis of both case-control and cohort studies revealed no significant difference (pooled OR = 1.03 [95% CI 0.99 -1.08], P = 0.104 and pooled OR = 0.98 [95% CI 0.99 -1.08], P = 0.186, respectively).</p><p><b>CONCLUSION</b>Paternal exposure to occupational electromagnetic radiation is not correlated with the sex ratio of the offspring.</p>
