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).
Approximately 1 percent of people with the disorder die suddenly each year, usually because of a too-rapid heartbeatâand many of them are young and unaware they even have heart issues. In fact, hypertrophic cardiomyopathy is the most common cause of sudden cardiac death in people younger than 30. If you hear of an athlete falling dead on the field, this condition often takes the blame.
