The problem is a little complicated. First of all, we need to know about the onset of psoriasis although genetic factors are important, may occupy a little proportion in the on the pathogenesis of psoriasis, that is to say, may the child born in psoriasis psoriasis patients than on the risk of psoriasis patients born child is high, but the child that is not to say that in patients with psoriasis psoriasis will occur. At present, although many achievements have been made in the research on genetic factors of psoriasis, the specific contribution of genetic factors in the pathogenesis of psoriasis has not been fully explained, and scientists from all over the world are making intensive studies. China has been in the forefront of psoriasis genetics research in the world, but there is still a long way to go to fully reveal the genetic mechanism of psoriasis.

        In theory, if both parents have psoriasis, then their children have at least a higher chance of developing psoriasis than children born to normal couples. A few studies have found that single parent suffering from psoriasis, its children is about 16% more at risk, and parents suffer from psoriasis, its children is about 50% more at risk, however, this study has many critics, because in the incidence of psoriasis, environmental factors also play an important role, the couple both sides in the same or similar environment may also affect their children psoriasis pathogenesis, even their children and their parents in the same or similar environment, these factors for the occurrence of psoriasis may produce certain contribution.

        So, the couple are both psoriasis patients, can pregnant? This issue should be decided by the couple, there is no provision in the law of our country, psoriasis itself is not the legal provisions of pregnancy disease category. Although both couples have psoriasis and the likelihood of psoriasis in their children is theoretically high, pregnancy is not prohibited.
