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).
Left ventricular hypertrophy is thought to be the leading cause of sudden cardiac death in the adult population. This is most commonly the result of longstanding high blood pressure which has caused secondary damage to the wall of the main pumping chamber of the heart, the left ventricle.
