Queens University Logo Earlier this year, we were informed that placing a laptop on the lap for long hours decreases fertility among men. And here is another investigation which highlights the probable harmful effects of technology on male fertility. A team of investigators have found that cell phone use increases the level of testosterone circulating in the body and therefore lowers sperm quality and declines fertility.

At the time of the study, it was pointed out that men using cell phone probably had higher levels of circulating testosterone. However, they allegedly had lower levels of luteinizing hormone (LH) as well. This reproductive hormone is assumed to be secreted by the pituitary gland in the brain.

Rany Shamloul, a postdoctoral fellow in the Department of Pharmacology and Toxicology and lead researcher on the project and colleagues presume that electromagnetic waves (EMW) emitted by cell phones have a dual action on male hormone levels and fertility. The study believes that EMW elevates the number of cells in the testes that produce testosterone and also blocks the conversion of this basic circulating type of testosterone to the more active, potent form of testosterone associated with sperm production and fertility.

Further investigations have to be conducted to ascertain the precise ways in which EMW affects male fertility.
