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.
In young adults and in individuals above the age of 35 the most important cause of sudden cardiac death is a heart attack (myocardial infarction) caused by a blood clot that obstructs the blood and oxygen flowing to a part of the heart. The damage this causes can induce potentially fatal cardiac arrhythmias.
