Semen samples were collected from healthy, nonsmoking donors (n=12) and examined at different times after exposure (immediately, after 2 h, and after 24 h).
Phosphatidylserine (PS) is a key phospholipid component of eucaryotic cell membrane and found almost exclusively on inner leaflet of the plasma membrane lipid bilayer in normal healthy cells. PS externalization is an important physiological signal (for example, in the apoptotic process).
|Exposure duration||continuous for 60 min.|
Mobile phone exposure had no statistically significant effect on any of the parameters studied. The data suggest that the impairment of male fertility reported in some previous studies (see "related articles") was not caused by the induction of apoptosis in spermatozoa.
