The vas deferens is the small tubes that transport the sperm cells from the testes. As stated by ScienceDaily, “it is composed of high molecular weight polymer powder dissolved in dimethyl Sulfoxide (DMSO), a biocompatible solvent.” (ScienceDaily) The resulting vasalgel implant remains in a soft gel-like state that allows water-soluble molecules to pass but not larger structures, such as spermatozoa. This quality is thought to be beneficial for preventing back-pressure on sperm storage areas.The contraceptive effect lasts for years, and, more importantly, is developed to be reversible by a second injection to dissolve the Vasalgel.
