Infectious diseases
Some patients suffer from chronic infectious diseases. In particular, an infection with Hepatitis B, Hepatitis C and HIV puts into question the ability to have a child without putting into danger one's partner or the child. The approach adopted differs depending upon which partner is infected and the chronic form of the disease. If the man is infected the seminal fluid must be specially prepared. This is to ensure that the virus will not be transmitted to the egg cell or the mother.
There is some possibility to check whether the seminal fluid is free from viruses after the preparation. If the woman is infected, medical therapy prior to, and during, pregnancy, immunization of the child, and a caesarean section birth will be employed to prevent infection of the child. While these methods have led to much progress in this area, it must be said that a residual risk remains. There is no 100% certainty that the infection will not be transmitted to the partner or child.
