Abstract
The effects electromagnetic wave (EMW) (900 MHz) emitted by mobile phones, for 60 days, upon the testis weight and epididymal sperm quality in male guinea pigs were investigated. Twelve healthy male guinea pigs were assigned randomly as the treatment (n=6) and control (n=6) groups. Treatment group (group EMW) was exposed to electromagnetic field of 900 MHz (217 Hz pulse rate, 2 W maximum peak power, SAR 0.95 w/kg) emitted by a mobile phone (used daily as; 20 min calling, then kept in ‘standby’ position for 23 h 40 min/day) for 20 min per day for 60 days. Control group (Group C) was maintained under similar conditions, with no radiation. Unlike the males in Group C kept in a separate room, those in exposed-group were subjected to electromagnetic radiation being operated at 900 MHz EMW field. There were not significant (P>0.05) differences between the groups based on the testicle weight (3.6 g vs. 4.4 g), sperm motility (61.7% vs. 70.0%), and abnormal sperm rate (5.8% vs. 3.7%) in treated and control males, respectively. However, there was a significantly (P
Özet
Bu çalışmada, rutin kullanımdaki mobil telefondan yayılan 900 MHz’lik elektromanyetik alana (EMA) 60 gün süreyle maruz kalan erkek Gine domuzlarında testis ağırlığı ve epididimal sperm kalitesi araştırıldı. Oniki adet sağlıklı erkek kobay rastgele uygulama, EMA (n=6) ve kontrol, K (n=6) grubu olarak iki gruba ayrıldı. Uygulama grubu (Grup EMA), 60 gün süre ile her gün mobil bir telefonla yayılan (telefonu 20 dk çaldırma/konuşma modu, 23 saat 40 dk uyku/standby modu) 900 MHz’lik EMA’a (217 Hz pulse rate, 2 W maximum peak power, SAR 0.95 w/kg) maruz bırakıldı. Kontrol grubu (Grup K) benzer şartlar altında tutuldu, ancak radyasyona maruz bırakılmadı. Grup EMA ve K arasında, sırasıyla, testis ağırlığı (3.6 g ve 4.4 g), epididimal sperm motilitesi (%61.7 ve %70.0) ve anormal sperm oranı (%5.8 ve %3.7) bakımından anlamlı farklılıklar gözlenmedi (P>0.05). Bununla birlikte, Grup EMA’deki sperm sayısı (549.6 x 106 sperm/ml) Grup K’dekilerden (799.17 x 106 sperm/ml) önemli düzeyde (P
