In vitro fertilization and the risk of birth and developmental defects - facts and fictions Poland is being swept by a wave of discussions on various aspects of IVF application. Scientists of various disciplines are getting involved in these discussions as opponents to this form of procreation.

According to the psychological literature, men commonly use the information on the resemblance of offspring to self as an indicator of genetic relatedness. It seems, however, that in the absence of such a resemblance, similarity between a mother and a child might be important, (...) because a man has additional reason to doubt his own biological paternity when the child is dissimilar to his partner. This assumption has been verified in two empirical studies. (shrink)
