Gender selection is a fertility procedure used to choose the gender of a baby prior to conception.
Gender selection can be elective or for medical reasons. Elective gender selection is made when the parents have a preference in their child’s sex. Medical gender selection is used in the cases of sex-linked diseases. For example, muscular dystrophy and hemophilia are inherited from the mother but only affect male offspring. Certain other conditions impact one sex more than the other (Fragile X syndrome, autism, etc.)
Gender selection can be accomplished using Preimplantation Genetic Diagnosis (PGD) or Preimplantation Genetic Screening (PGS) in conjunction with in vitro fertilization (IVF). In addition to selecting chromosomally normal embryos, parents can choose to transfer embryos of the desired gender to the uterus.
