When unprotected sexual intercourse (specifically without condom - either because it tore or because it was not used in the relationship), there is a risk of occurring:
- Unplanned pregnancy;
- Infections due to sexually transmitted diseases (STDs).
THE condom (especially the male one) is an excellent method of barrier against infectious agents of sexually transmitted diseases. Although not 100% efficient, it can reach a value very close to this for most diseases and also for the prevention of pregnancy.
After unprotected sexual practice, some preventive measures may be taken in some particular cases. This includes, in relation to HIV, the use of up to 72 hours after sexual contact. These cases should be evaluated according to certain criteria, so the person should go to Outpatient Services for HIV and AIDS (SAE) or Testing and Counseling Centers (CTA). The addresses of these services in each region can be found on the website of the Department of STD, AIDS and Viral Hepatitis of the Ministry of Health or on the services page of the AIDS News Agency.
Regarding the prevention of pregnancy after unprotected intercourse, there is the possibility of using "pill of the next day", emergency contraceptive method which acts in various ways to prevent pregnancy in emergency situations (rape, condom failure, expulsion of the IUD, displacement of the diaphragm, the previously mentioned unprotected relationship, etc.). Ideally, other safe and effective long-term contraceptive methods should be used.
