No, in Portugal, as in the rest of Europe, free sex selection is not permitted by law; although it is true that there are techniques such as PGD (Preimplantation Genetic Testing) that allow us to know whether embryos in culture are male or female. However, although choice is not allowed, there are some exceptions, in those cases where the sole aim is to avoid the transmission of genetic diseases associated with the sex chromosomes. These exceptions are regulated in the Medically Assisted Procreation Law 32/2006, which also establishes that sex selection or genetic manipulation for non-therapeutic or unauthorised purposes is a very serious offence.
