Results of the Wilcoxon-signed ranks test are illustrated in Fig. 2. There was a statistically significant (p = 0.02) reduction in zona binding in RF-EMF-exposed sperms compared with that in controls. Controls bound an average of 31.8 ± 12.8 sperms per hemizona compared with 22.8 ± 12.4 sperms per hemizona of RF-EMF-exposed spermatozoa. Sperm […]
