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).
Conditions that can trigger sudden cardiac arrest include: â¢ Coronary artery disease. This is the most common cause of sudden cardiac arrest in people older than 35. â¢ Cardiomyopathy. When you have this condition, your heart muscle becomes enlarged or thick, so it's weakened. â¢ Long QT syndrome and Brugada syndrome. These disorders of the heartâs electrical system can cause abnormal heart rhythms.
