An IVF clinic in NSW has launched an advertising campaign asking men to donate their sperm, due to several depleted supplies.

With taglines including ‘A donation to us won’t save a life; hopefully it will create one’ and ‘You’ve got millions to spare, we only need one’, the campaign will reportedly run primarily online.

Fertility experts indicate that there are less than 10 registered sperm donors left in NSW, likely due to tougher restrictions on imported sperm and new legislation that gives children the right to know the identity of their donor father.

“If youre in your late thirties and deciding to have children, at that point, that 12 months can mean the difference between you becoming a mother or not,” IVF Australias Professor Michael Chapman he told the ABC.
