The average number of donation visits is between 4 and 8. In some situations, however, this number may increase or decrease slightly. Please note that prior to donation, a future sperm donor must be subjected to a qualification process (about 3 visits to the Clinic that involve performing a sperm examination, having a conversation with a psychologist and a conversation with a doctor). Once the qualification is successful, the donor makes several appearances at the Clinic to donate sperm. However, he can withdraw from the programme at any time. The frequency of donations is determined on an individual basis, but the donor generally attends the Clinic on a fortnightly basis, give or take.
