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).
What are sudden cardiac arrest and sudden cardiac death? Sudden cardiac death (SCD) is a sudden, unexpected death caused by loss of heart function (sudden cardiac arrest). Sudden cardiac death is the largest cause of natural death in the United States, causing about 325,000 adult deaths in the United States each year. Sudden cardiac death is responsible for half of all heart disease deaths.
