RISUG stands for Reversible Inhibition of Sperm Under Guidance, and it is a technology that may fill this void.
While the amount of research and innovation that have gone into developing RISUG is substantial, the way it works is simple: a compound is injected into the two tubes through which a man’s sperm flows before it leaves his body.
This compound stays in the tube and chemically breaks apart each sperm cell as it passes by. The result is a normal ejaculation full of nonfunctional sperm.
What makes this procedure unique, however, is the R in RISUG: Reversible. The compound can be easily rinsed out by a second injection which reverses all contraceptive effects (Lohiya et al. 2010).
This means that you (or a male partner) could chose now to become sterile for several years, then have the procedure reversed at a moment’s notice and regain virility. Many college-age males find this option extremely attractive; the option to remain sexually active with yet another safeguard against unwanted pregnancy.How many more people would choose a vasectomy if it was guaranteed safe and reversible?
