Under the AHR Act, there is no maximum age limit for sperm or egg donors. Under the Processing and Distribution of Semen for Assisted Conception Regulations (Semen Regulations) of the Food and Drugs Act, third-party sperm donors over 40years of age are not accepted. However, in exceptional circumstances a clinic may accept sperm donors outside this age group. No one under the age of18 may donate sperm or eggs, except for the purpose of creating a human being that the clinic reasonably believes will be raised by the donor. An example of this is oncology patients about to receive treatment that may cause infertility.
