Contraceptives will nonhormonal!

Polina Lishko University of California came up with the idea of ​​non-hormonal contraceptives. They can become a breakthrough in drug industry for birth control, since it does not have any side effects.

Dr. Lishko and colleagues caught signal "fertile attraction" between egg and sperm. Laboratory experiments have shown that the hormone that releases the egg is ready for fertilization, contains some sort of message to the sperm, which is less than a minute leads to a reaction.

This discovery, details of which are published in the scientific journal Nature, is the theoretical possibility of creating non-hormonal contraceptive That will work by turning off the data signals. Such drugs are, in turn, can displace from the market common birth control pills , As the new tablets will not have any side effects .

Polina Lishko conducted experiments on mice and on human sperm. She was able to measure the electrical signal that controls the movements of the sperm in their journey toward the egg. It turned out that if the sperm gets charge of progesterone (a hormone produced by cells surrounding the egg), the electric signal is amplified, and it makes the sperm move faster. Their ability to penetrate into the egg it increases.

Existing birth control pills   work due to the impact of hormones to suppress ovulation, ie developing egg. Unfortunately, these drugs have some pretty nasty side effects, increasing the risk of some types of cancer and cardiovascular disease.
