‘Reproductive parameters reported to be altered by EMF exposure include male germ cell death, the estrous cycle, reproductive endocrine hormones, reproductive organ weights, sperm motility, early embryonic development, and pregnancy success’

Reduced male fertility may be making it even harder for couples to conceive and has possibly been contributing to low birth rates in some countries (Source). A meta-analysis looking at sperm count for the past 38 years across 50 countries has confirmed that the average male sperm count has dropped over 50 percent.
A 2008 study of 360 men discovered that frequent use of cell phones may actually decrease the semen quality in men. This study found that men who used their cell phones more frequently and had higher exposure to cell phone emitted EMF also had a decrease in their sperm count, motility, viability, or normal morphology.

In 2011, Researchers from the Medical University of Gaz, Austria and Department of Pharmacology and Toxicology at Queen's University in Canada have also found that while cell phone use appears to increase the level of testosterone circulating in the body, it may also lead to low sperm quality and a decrease in fertility.

Multiple other studies have followed suit and found supporting evidence that men using mobile phones have decreased sperm concentration, decreased motility, normal morphology, and decreased viability. (Source)
