We are pleased to announce that, thanks to the financial support of our valuable
users, we are able once again, to import articles from the radio frequency range into
the EMF-Portal. Fortunately, we could close the gap in our literature inventory and
all newly published articles released up to April 30, 2018 have been included. In
order that we are able to import further publications released in the future, please
help us with your donation. Thank you very much!
To determine a possible relationship between regular cell phone use and different humansperm attributes.
A total of 371 men of reproductive age were included, who presented at the authors clinic because of infertility problems. The categories of motility were: percentage of rapid progressive motilesperm (grade A), percentage of slow progressive motilesperm (grade B), percentage of non-progressive motilesperm (grade C), and percentage of immotile sperm (grade D), according to the WHO standards.
For the study men of reproductive age were divided into the following groups: men who used cell phones for less than 15 min/day, those who used for 60 min/day, those who kept the cell phone in standby position within 50 cm for less than 1 h/day and those who kept their cell phones in the standby position within a distance of 50 cm for more than 20 h/day.
