Sexuality is one of the most important aspects of human life, and it is a condition which defies death and inc-reases the quality of life. The child may be the object of the sexual activity or an unwanted side-ellectin this connection, contraception may offer a more qualified possibility of sexual life. Although there are some convictions that schizophrenics are hyposexual, it can not be overloaked that psychotic patients do have sexual lives. A primary structural disturbance specific to schizophrenia has not been established, although the studies carried out show that these patients have mostly chaotic sexual lives. In these studies the following are seen frequently: jemale patients not having efficient contraception, disturbance of judgment, disturbance of behaviour, to be the subject of forceful sexual intercourse, rape,sexual activity in return for something. As a consequence, there have been abortions, venereal diseases, and unplanned and unwanted pregnancies. Pregnancy affects the patient and the course of the disease unfavourably. It is obvious that the unborn child will be affected by the disease of his or her parents. A variety of factors play a role in this condition. When all these are considered, the role and importance of contraception, sterilization, and ethics become obvious. There is no worldwide consensus regarding the ethics on the subjects of sexuality, contraception, parenthood, and sterilization, for the schizophrenics, and the complaints of patients that there are so few psychiatnists to inform them on these subjects have caused this study to be carried out to remind this problem to these interested and to realize the pnactical aspects of the subject.
