  11. Semen
    11.1. Only semen certifiable for export to Australia was used to fertilise the oocytes. Documentation was provided to the CFIA for verification.
    11.2. Canadian origin semen comes from a semen donor who has been resident in Canada for 90 days prior to the collection of semen used to fertilise the oocytes in this consignment,
    11.3. If the semen was collected in another country, the semen importer provided a copy of certification from the country of origin to the CFIA as evidence that the semen met Australian import requirements.

    14.2. Only embryos from the same female donor were washed together, and no more than ten embryos were washed at any one time.
    14.3. The zona pellucida of each embryo, before washing, was examined over its entire surface area at not less than 50X magnification to ensure that it is intact and free of adherent material.
    14.4. The embryos were washed at least ten times with at least 100–fold dilutions between each wash, and a new sterile micropipette was used for transferring the embryos through each wash.
    14.5. The standard washing procedure includes additional washes with the enzyme trypsin.
    14.6. Eligible embryos include those subject to micromanipulation only for the purpose of collecting biopsy samples for genetic analysis. No other micromanipulations such as splitting, transgene injection, intracytoplasmic sperm injection, nuclear transfer or other interventions that breach the integrity of the zona pellucida of embryos are permitted.
