Birth Control Pill Without Hormonal Side Effects Coming

By KJ Mullins     Oct 17, 2007 in Health
An American Society for Reproductive Medicine has been informed that a new type of oral contraceptive is in the works without the side effects that are associated with current brands.
Side effects like nausea, headaches, and low sex drive and raise slightly the risk of DVT and strokes shouldn't be a problem for the new pills are all good news. The bad news though is the newer type of pill is at least a decade away and may carry different side effects reports BBC.
The new pill will interfere with the RNA of the egg just before it is fertilised. A gene that was recently identified, ZP3 produces a protein that allows the sperm to bind to the surface of the egg. By eliminating the ZP3 then the egg can not be fertilized and a pregnancy can not occur.
Dr Zev Williams, who presented the research to the conference, said: "We simply don't have a contraceptive drug that is non-hormonal and reversible.
"What we are trying to do is to think about contraception in a new way.
"Obviously there are going to be hurdles and it is going to take a lot of time, but the need is there and we think it can be achieved."
By not using hormones as birth control then the side effects from hormonal pills will be eliminated.
While the news is great for the future it will take years of research to perfect.
Dr Martin Fabani, a researcher in the technique at Cambridge University, said that obstacles would need to be overcome, and that there was no guarantee that side-effects could be avoided completely.
He said: "RNA interference is fantastic and there was a big hype around it, but people are starting to see what we call 'off-target' effects - where the therapy has an unwanted effect elsewhere in the body.
"Every single application has some degree of off target effects."
