Our right to in vitro fertilisation--its scope and limits

There exists a derived negative right to procreative freedom, including a right to in vitro fertilisation (IVF) and to the exercise of selective techniques such as preimplantation genetic diagnosis. This is an extensive freedom, including not only the right to the exercise of a responsible parenthood, but also, in rare cases, to wrong decisions. It includes also a right for less than perfect parents to the use of IVF, and for IVF doctors to assist them, if they want and can agree about the terms.
