The donor's identity is not shared with the recipient or the child. Non-identifying information (medical history, physical traits) is typically still available.
In South Africa, donor sperm is available through private fertility clinics, either from locally recruited donors or imported from international sperm banks. Donors are screened, matched to you by the clinic, and can be anonymous or identity-release depending on your clinic and preferences. More structured than a known-donor journey, which for many people is exactly the point.
Even with clinic-led IUI, knowing your own cycle data shortens timelines.
Choosing a South African fertility clinic that fits, different clinics specialise differently.
Some people land on sperm bank by default. Worth seeing the alternative properly.
