Abstract

Günümüzde teknolojik gelişmelerin geldiği bu noktada, iletişim araçları çeşitli ve yaygın kullanım alanlarına sahip olarak günlük yaşantımıza çeşitli kolaylıklar getirmiştir. Son yıllarda iletişim çağının inanılmaz bir hızla gelişimine paralel olarak yaşamımıza giren elektronik cihazlar; telsiz, cep telefonu, internet ağları gibi teknoloji ürünleridir. Yaşantımıza kolaylıklar sağlarken birtakım olumsuzlukları da beraberinde getirmişlerdir. Bu etkiler, çoğu kişi tarafından önemsenmeyen ve etkisini uzun zaman sonunda gösteren elektromanyetik alanın (EMA) zararlarıdır. Kablosuz yerel alan ağları (WLAN, Wireless Local Area Networks), iki yönlü geniş bant veri iletişimi sağlayan, iletim ortamı olarak fiber optik veya bakır kablo yerine telsiz frekansı (RF, Radio Frequency) veya kızılötesi ışınları kullanan ve salon bina veya kampüs gibi sınırlı bir alanda çalışan iletişim ağlarıdır. Kablosuz ağların testis dokusu ile ilişkisini incelememizde; testis dokusunun sperm üretiminin gerçekleştiği doku olması ve bu dokuda oluşabilecek olası tahribatın üreme sistemini etkileyeceği, testis dokusunun gerek iyonize gerekse noniyonize radyasyona duyarlı organ olması ve kullanıcıların dizüstü bilgisayarlarda kablosuz ağlar aracılığı ile internet bağlantısını kullanması büyük bir rol oynamıştır. Manyetik alanın etkilerinden biri olan ısı artışının testis dokusunda histopatolojik değişiklikler meydana getirmesidir.
