For centuries, women have so many responsibilities in the house and if she is married they triple. Despite huge strides in the feminist movements, women are still expected to cook, clean, take care of the kids, and still look fabulous and perform in the bedroom. AND we have been expected to supply birth control, especially if we decided not to use condoms with our partner: we HAVE to be the one to be on birth control.
Well modern science isn't letting us down and continue to try to develop a male contraceptive; at least one that exists beyond condoms or a vasectomy. Reversible Inhibition of Sperm Under Guidance or RISUG. I am all for men taking more responsibility in preventing pregnant, now if scientist can figure out to impregnate men, then I believe society will change and men will start to help around the house more.
RISUG is an injectable compound that partially blocks the vasa deferentia (tubes that carry sperm), providing effective contraception for up to 10 years per dose. It is effective immediately, has few side effects, and has proven to be reversible in primate studies. This contraceptive has completed Phase I and II clinical trials in India (Guha 1997).
How does it work?
Healthy sperm have membranes that carry molecular keys needed to attach to an egg. Without these keys, sperm are infertile. RISUG raptures the membranes of the sperm giving them membranes unable to attach to an egg.
Preclincial trials in the US are expected to be completed by the end of 2011 with clinical trials in men starting in the next 5 years. Which means, don't look for RISUG at your doctors office anytime soon. Until it's approved men still need to rely on condoms or the big "V".
