Chances to have a boy after gender selection by pre-implantation genetic screening are reduced in couples with only girls and without a boy sired by the male partner

ABSTRACT

Background: Gender selection and family planning have their roots in human history. Despite great interest in these fields, very few scientific propositions exist which could explain why some family do not attain the desired sex. Therefore, the aim of this study was to evaluate whether sex of previous child or children could affect the outcomes of pre-implantation genetic screening [PGS]
