"THE POLYMER"-Illustration of Procedure, RISUG Part 2.


2. The polymer= a compound of styrene+maleic anhydride (or SMA, an ingredient in floor polish, which led to a halt in Guha’s lab experiments due to the possibility of it being Toxic) and dimethyl sulfoxide (or DMSO, a common solvent) anchors itself to the tiny folds in the vas, clinging to the tissue. Sperm and other fluids can still get through, avoiding the backup pressure sometimes associated with a vasectomy.

Illustration of Procedure, RISUG Part 1.



Reversible vasectomy is synonymous to a Regular Vasectomy: 
Similarity=The surgeon makes a small puncture in the scrotum and extracts the vas deferens, a slender white tube. 
Difference=The disparity is in the fact that rather than severing the vas, the doctor would instead inject the vessel lengthwise with a nontoxic, stable polymer mixture. This process is repeatable on the other side.

Introduction/ Summary of RISUG (Reversible Inhibition of the Sperm under Guidance)

 -General Overview (The Breakthrough)
In India, maverick Indian Scientist, Sujoy Guha, has made a breakthrough in Birth Control, after endeavouring for thirty years, refining  the new idea of a new method of birth control whilst dealing with political ramifications. This new method abbreviated as RISUG, which would represent one of the biggest advancements in male birth control since the invention of the male condom. RISUG would be the equivalent of the female Birth Control Pill, though facing harder conditions ahead to be approved. RISUG  constitutes of a nontoxic polymer that forms a coating on the inside of the vas, of which chemically incapacitates the sperm, resulting in them being incapable of fertilization
 -Testing (1993 first testing) and Commercialization and Globalization
RISUG has performed well, with all subjects were azoospermic, hence explicitly showing its effectiveness. Further along, leading Canadian Vasectomy and member of WHO, Ronald Weiss attempted to commercialized the procedure in US but was unable to find a corporate partner. Prior to that Guha’s new method has been gaining attention beyond India and is flooded with email on queries. Succeeding Weiss was a woman named Elaine Lissner founded a nonprofit advocacy group, financially supporting RISUG’s developments.
