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.
Sudden cardiac death (SCD) is a sudden, unexpected death caused by loss of heart function (sudden cardiac arrest). It is the largest cause of natural death in the U.S., causing about 325,000 adult deaths in the U.S. each year. SCD is responsible for half of all heart disease deaths.
Sudden cardiac arrest (SCA) is also called sudden cardiac death. Sudden cardiac arrest occurs when the heart suddenly stops beating, which stops oxygen-rich blood from reaching the brain and other organs. A person can die from SCA in minutes if it is not treated right away. Sudden cardiac arrest is not a heart attack, even though you may hear the terms âheart attackâ or âmassive heart attackâ used to describe it. A heart attack happens when blood flow to a part of the heart is slowed or stopped, usually because of plaque rupture in one of the coronary arteries.
