Reversible inhibition of sperm under guidance
Reversible Inhibition of Sperm Under Guidance (RISUG)
Reversible Inhibition of Sperm Under Guidance (RISUG), pronounced as /ˈrɪsʌg/, is a male contraceptive method that is currently under clinical trials. The term is derived from the English words "reversible", "inhibition", "sperm", "under", and "guidance".
Definition
RISUG is a form of male contraception that is long-lasting and reversible. It involves the injection of a polymer gel into the vas deferens, the tube that carries sperm from the testicles, which blocks or breaks down sperm to prevent pregnancy.
History
RISUG was developed by Dr. Sujoy K. Guha, a biomedical engineer at the Indian Institute of Technology in the 1970s. The method has been under clinical trials in India since the 1990s.
Mechanism of Action
The RISUG method works by injecting a polymer gel into the vas deferens. This gel carries a positive charge, which neutralizes the negative charge of the sperm, rendering them unable to fertilize an egg. The procedure is reversible through another injection that dissolves the gel.
