Typical lubricants have higher particle concentrations then sperm can tolerate which can cause them to stop moving and render them unable to fertilize an egg. In contrast, Preseedâs osmolality matches that of semen and thus does not harm or damage sperm.
Most sudden cardiac deaths are caused by abnormal heart rhythms called arrhythmias. The most common life-threatening arrhythmia is ventricular fibrillation, which is an erratic, disorganized firing of impulses from the ventricles (the heart's lower chambers).
In young adults and in individuals above the age of 35 the most important cause of sudden cardiac death is a heart attack (myocardial infarction) caused by a blood clot that obstructs the blood and oxygen flowing to a part of the heart. The damage this causes can induce potentially fatal cardiac arrhythmias.
