From locations in Australia (also see To send preserved samples)
Semen stored in the correct buffered formal saline solution usually gets to us in good condition whether it comes via courier or via Australia Post.
Notes for Australia Post:
We recommend padding well with bubble wrap or the use of a padded post pack. The use of paper envelopes is not recommended as vials may be shattered by sorting machines.
Other general problems
Clip top vials need to be checked to make sure they are properly closed front and back. Semen not stored in the correct buffered formal saline has arrived in poor condition and has not been able to be assessed. Some abnormalities seen in sperm have been caused by the wrong preservative being used.
