Future Dads: Keep Your Cell Phone Out of Your Front Pocket

If you plan to father a child, don’t keep it in your pocket – your cell phone, that is.

The reason: the number of hours you use your cell phone each day may affect your sperm profile and future fertility.

A new study by a team of international researchers led by those at Queen’s University in Kingston, Ontario, adds to the evidence that men who have been diagnosed with poor sperm quality and who are trying to have children should limit their cell phone use.

The researchers found puzzling results.

While cell phone use led to an increase in the level of testosterone circulating in the body, it also led to lower levels of luteinizing hormone, which is a key reproductive hormone secreted by the pituitary.

Previously, Cleveland Clinic researchers have noted an association between cell phone use and sperm quality.

The more hours men from an infertility clinic spent on their cell phones each day, the lower their sperm count and the greater their percentage of abnormal sperm.

Men who used their cell phone for more than four hours a day had the lowest average sperm counts and the greatest percentage of abnormal sperm.

The effect of cell phones on sperm parameters may be due to the electromagnetic radiation the devices emit or to the heat they generate.

The Canadian researchers believe electromagnetic radiation may block the conversion of circulating testosterone to the more active, potent form of testosterone associated with sperm production and fertility.

While there is a strong association of cell phone use with decreased semen quality, this does not prove a direct cause-and-effect relationship.

Further studies will be necessary to identify the mechanism involved in the reduction of sperm quality due to cell phones.

The Cleveland Clinic researchers are doing a follow-up study in a large group of men that also takes into account other lifestyle habits and occupational exposures that might affect sperm quality.

In the meantime, Marc Goldstein, MD, Director of the Center for Male Reproductive Medicine and Microsurgery at Weill Cornell Medical College says, “there may not be conclusive evidence but I recommend that a man not keep a live cell phone in his front pants pocket.”
