When planning a pregnancy

Women with a negative blood factor may experience rhesus-conflict with the child during pregnancy. If the father's antigen is inherited, which is alien to the woman's body, it will lead to the production of antibodies and the appearance of an immune conflict. Incompatibility develops in the first group in the fairer sex who has a negative Rhesus if the man with a positive factor and gave it to the child.

If the child has a negative blood group, there will be no Rhesus-conflict. In case of incompatibility, the most complicated course of pregnancy is most often observed. A woman needs dynamic observation, intensive treatment, early delivery if necessary. Rhesus-conflict usually does not occur with the first pregnancy, but with repeated - almost always.

Sometimes in the female body, antisperm antibodies are produced that destroy the spermatozoa. Such couples often have problems with conception. That is why during the pregnancy planning period it is recommended that a woman be tested for antisperm antibodies.
