Section 15 of the Human Reproductive Technology Ordinance sets out prohibitions in connection with embryos, against sex selection and against the provision of reproductive technology to unmarried couples:

         1. bring about the creation of an embryo; or
         2. combine human and non-human gametes or embryos or any part thereof such as to give rise to a two-cell zygote;
      2. keep or use an embryo after the appearance of the primitive streak;
      3. place any non-human gametes or embryo or any part thereof in any human;
      4. place any human gametes or embryo or any part thereof in any animal;
      5. replace the nucleus of a cell of an embryo with a nucleus taken from any other cell; or

   3. No person shall, by means of a reproductive technology procedure, cause the sex of an embryo to be selected, whether directly or indirectly (including by the implantation of an embryo of a particular sex in the body of a woman), except where-–
      1. the purpose of such selection is to avoid a sex-linked genetic disease specified in Schedule 2 which may prejudice the health of the embryo (including any foetus, child or adult which may arise from the embryo); and
      2. not less than two registered medical practitioners each state in writing that such selection is for that purpose and such disease would be sufficiently severe to a person suffering it to justify such selection.
   4. For the purposes of subsection (1)(b), the primitive streak shall be taken to have appeared in an embryo not later than the end of the period of 14 days beginning with the day when the gametes are mixed, not counting any time during which the embryo is stored.

   6. Without prejudice to the operation of section 14 , subsection (5) shall not apply in the case of a reproductive technology procedure provided to a person who is to be a surrogate mother where the procedure is provided pursuant to the surrogacy arrangement under which she is to be the surrogate mother.
   7. It is hereby declared that-
      1. subject to paragraph (b), subsection (5) shall not operate to prohibit the continuation of a reproductive technology procedure provided to persons who were the parties to a marriage when gametes were, or an embryo was, placed in the body of a woman pursuant to the procedure;
      2. paragraph (a) shall not operate to permit any further gametes or further embryo to be placed in the body of that woman pursuant to that procedure.
