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.
The mechanism of death in the majority of patients dying of Sudden cardiac death is ventricular fibrillation. Structural changes in the diseased heart as a result of inherited factors (mutations in ion-channel coding genes for example) cannot explain the suddenness of SCD.
