Reproductive Effects

Exposure to RF fields of sufficient intensity to cause thermal effects can cause reproductive effects (ICNIRP, 1998; UK Independent Expert Group, 2000). The power produced from mobile phones or their base stations, however, is far too low to cause such whole body heating. Studies demonstrate that there is no scientific evidence to suggest that exposure to radiofrequencies from mobile phones and base station antennae cause miscarriages or birth defects (Jensh 1997; Bornhausen 2000; Dasdag, 2000). In a comprehensive review, O'Connor (1999) stated:

" All studies in which effects have been observed have been above recommended maximum permissible exposure levels. Even at high levels, consistent morphological or organ abnormalities have not been reported".

In another review, Heynick and Merritt (2003) stated:

"In conclusion regarding experimental studies with nonhuman species, teratogenic effects can occur in both nonmammalian and mammalian subjects from RF EMF exposure, but only at levels that produce significant internal temperature rises. Such positive findings were consonant with those of experiments with various nonRFEMF heating modes."
Dasdag et al. (1999) found some changes in testicular function in rats exposed to 915 MHz at a SAR of 0.141 W/kg, although the rectal temperature of the affected rats was elevated. Another study by the same group, however, found no changes in testicular function in rats exposed to 900 MHz RF radiation for 20 minutes per day for one month (Dasdag, 2003). Yan (2007) reported that exposure of rats to RFR from a cell phone for 6 hours a day was associated with a higher incidence of sperm death and abnormal clumping of sperm cells.

Tofani et al. (1986) reported an increased miscarriage rate and reduced body weight in pregnant rats exposed to 27.12 MHz continuously during pregnancy.

Panagopoulos (2004) reported that exposure to a field from a GSM 900 MHz phone for 6 minutes daily for 5 days could decrease the reproductive capacity of the insect Drosophilia melanogaster.
