Men who have been diagnosed to have poor sperm quality and were trying to have children should limit their cellphone use. Researchers have found that while the use of mobile phones increase in circulating testosterone in the body, it also can cause low sperm quality and fertility decline.
"Our findings are a bit confusing," said Rany Shamloul, principal investigator who is a postdoctoral fellow at the Department of Pharmacology and Toxicology.
"We're hoping to find different results, but we found the results confirmed that there may be some mechanism that mengadung intrigue in the process," he added, as quoted Health24, Monday (23/05/2011).
Affect hormone levels
The research team found that men who reported high levels of use of their phones have the levels of circulating testosterone are also high. But it turns out, the level of luteinizing hormone (LH)-an important reproductive hormone released by the pituitary gland in the brain-becomes lower.
The researchers hypothesize that the electromagnetic waves (EMW) emitted by mobile phones have dual action on hormone levels and male fertility.
EMW can increase the number of cells in the testes which produce testosterone by lowering levels of LH released by the gland in the brain. EMW also hinder circulation changes testosterone into a form that is more active and powerful that is associated with sperm production and fertility.
Researchers hope, in-depth and sustained research is needed to determine appropriate ways how EMW affect male fertility.
