==Introduction==
Have you ever wondered how could your life change if you find out that you are affected by a STD? 
In fact, nobody is safe, because if you're sexually active you're potentially exposed to any STD. 
There are different kind of STDs, some are easier to live with and some other are fatal. 
More than 40 million people are living with some of these deseases and their number is rising rapidly.
The worst affected region by far is Sub-Saharan Africa with almost 30 million people concerned. 
The world's highest rates are found in Southern Africa where adult prevalence most countries exceeds 25%. 
In 2003, the number of people living with some of these deseases reached 1.8 million in Eastern Europe and Central Asian, and 9.5 million in Asia and the Pacific.The number of affected people is rising every day, at the same time are we able to do something to avoid it? contraception plays a gigantic role in the solution of this problem. However, contraception also inhibit reproduction. 
We will try to define what is a STD and how can we manage to deal between contraception and reproduction.

==What do STDs mean?==
STD is the abbrevation of ''sexually transmitted diseases''. STDs are contagious diseases which are spread by sexual contact. These diseases can be controlled by medications, but the symptoms are not always visible,and so the risk of contamination is high. In addition, since their symptoms are not rapidely apparent, people can live feeling fine. However, many STDs cause problems in long term and if they stay untreated it can be fatal. So, anyone who is sexually active has to have regular check up for STDs!!!

=How does contraception be linked to STDs?=

It is a little hard to define precisely the link between contraception and STDs. 
In one hand, contraception doesn't allow the creation of life but if two partens want to have a baby they have to stop the contraception to allow the regular cycle of reproduction. 
Although, in another hand if the partners decide to stop contracpetion they are exposed to increased risks of STD contamination. 
Despite, they have never had another sexual partner before. 

The condom is the most efficient way to avoid pregnency and STDs contamination, but it has to be used perfectly. It means that condoms have to be used at every sexual relations and with a correct way. If the condom is used with a classic way (it means irregular and incorrect way) and not with a perfect way, the risk of being pregnant is from 10 to 14 per cent. 
Therefore, it is not the condom failure. We speak about condom failure when it breaks or slides during the sexual relation.
In addition, it was proved that STDs can not pass through an undamaged latex condom.

It was also tested that if a person who is infected by the VIH virus has a sexual relation with one who is clean (using regularly a condom), the risk for the clean person to be infected is less than 1% per year. Therefore, it means that if an infected person uses with an irregular way the condom it can be as dangerous as if he doesn't use it at all.

There are several ways for contraception. Some are more adequate to men and others are more adequate for women (see previous informations concerning different ways of contraceptions).

=Conclusion=
In conclusion, the only way to inhibit STDs is the condom, there is no other way. 
The pill doesn't inhibit at all the transmission and the contamination of STDs, it just acts as a way of contraception because it inhibits the fertilization to start. Whereas, this latex barrier, the condom, acts as a way of contraception in addition of avoiding the risk of transmiting some diseases to our partner (in the case where we are infected) or get infected.
Of course, the best way to proctect itself and our partner is the combination of the condom and the pill, the protection is absolutely assured! They avoid to get infected by STDs and have undesirable babies.
