When to avoid creating surplus human embryos.

The advice that should be given to a couple considering assisted reproductive technologies for the treatment of their infertility, when they are completely opposed to the destruction of surplus embryos, is discussed. It is urged that they do not use treatments that generate surplus embryos. They should be given the options of declining IVF and considering adoption, or less efficient treatments, namely limited ovarian stimulation, limited insemination of available ova or natural cycle IVF where no surplus embryos are generated.
